John Charles Frémont (1813–90) has been celebrated by historians as one of the most noted nineteenth-century explorers of the American West (figure 1). During a period of twelve years (1842–54), he personally led and directed five western expeditions to (1) South Pass and the Wind River Range in Wyoming in 1842; (2) the interior of the Rockies and the Pacific Coast in 1843–44; (3) California through Colorado, northern Utah, and central Nevada in 1845; (4) southern California through southern Colorado, New Mexico, and southern Arizona in 1848–49; and (5) northern California through southern Colorado, southern Utah, southern Nevada, and central California in 1853–54. Significantly, during his second expedition (1843–44), he traversed the interior of the Rockies (including northern, southern, central, and eastern Utah) and the Pacific coast. Following Fremont’s second expedition (1843–44), Frémont went to Washington, DC, where in collaboration with his wife, Jessie, he completed writing a report and producing detailed maps of both the 1842 and 1843–44 western expeditions. In 1845, Congress approved the printing of ten thousand copies of Frémont’s Report of the Exploring Expedition to the Rocky Mountains in the Year 1842, and to Oregon and North California in the Years 1843–44.
Editors around the country peaked the public interest even further by including excerpts from the volume in their newspapers, which resulted in an even larger nationwide readership. Ultimately, the publication of the Report and the publicity that surrounded it, generated a growing national interest in the West, and fanned the flames of Oregon fever and U.S. expansionism among politicians, capitalists, adventurists, and unsettled Americans who believed that the remote regions of the west offered new possibilities of unlimited prosperity.

Among those significantly impacted by Frémont’s early western explorations were the Mormons residing in western Illinois. The explorer’s favorable descriptions of the Bear River region, the Salt Lake Valley, and the Great Basin (the name Frémont gave to the territory) had a profound influence on Brigham Young and the Church’s leadership in their decision to select the Wasatch region of northern Utah as the main place of Mormon settlement.
Frémont’s 1843–44 Expedition in the Utah Region
On March 10, 1843, Lieutenant Frémont received official notice from Colonel J. J. Abert, chief of the Army Topographical Engineers, to head a second expedition to the Far West. Abert’s instructions were for Frémont to map and survey the headwaters of the Arkansas River on the boundary between the Mexican and American borders in Colorado, then to do the same for the territory lying west of the Wind Rivers in Wyoming to the Columbia River on the Pacific. It was anticipated that the fulfillment of these objectives would provide the government a more accurate definition of the boundary between the United States and Mexico. Furthermore, when combined with Frémont’s 1842 survey of the area between the Kansas River and the Wind River Mountains, it was anticipated that the two reports would provide a detailed description (along with maps) of the entire route from the Missouri River to the Pacific.
Frémont’s 1843–44 expedition party, consisting of thirty-nine men, left Westport Landing (Kansas City, Missouri) on May 29, 1843. The party traveled west through Kansas to Pueblo, Colorado, then north through the Medicine Bow Range in southern Wyoming, where they eventually reached the North Platte River, the Sweetwater River, and South Pass on the Oregon Trail. The expedition subsequently followed the Big Sandy River downstream, crossed the Green River, Blacks Fork, and Hams Fork, and then proceeded upstream on the Muddy River, where they reached the banks of the Bear River on August 21. Upon the expedition’s arrival at the Bear River in western Wyoming, the lieutenant recognized that he was on the main tributary of the Great Salt Lake, which had been the subject of mystery and folklore among western travelers. Frémont recorded:
We are now entering a region which for us possessed a strange and extraordinary interest. We were upon the waters of the famous lake which forms a salient point among the remarkable geographic features of the country, and around which the vague and superstitious obscurity which we anticipated pleasure in dispelling, but which, in the meantime, left a crowded field for the exercise of our imagination. . . .
Hitherto this lake had been seen only by trappers who were wandering through the country in search of new beaver streams, caring very little for the geography; its islands had never been visited; and none were to be found who had entirely made a circuit of it shores; and no instrumental observation or geographical survey, of any description had ever been made anywhere in the neighboring region. It was generally supposed that it had no visible outlet; but among trappers, including those in my own camp, were many who believed that somewhere on its surface was a terrible whirlpool, through which its waters found their way to the ocean by some subterranean communication. All these things had made a frequent subject of discussion in our desultory conversations around the fires at night; and my own mind had become tolerably well filled with their indefinite pictures, and insensibly colored with their romantic descriptions, which, in the pleasure of excitement, I was well disposed to believe. And half expected to realize.
Frémont considered the exploration of the Great Salt Lake so important to the success of the entire expedition that upon the party’s arrival at the big bend of the Bear River, for a period of twenty-six days (from August 25 to September 19), he left the main course of the Oregon Trail so that he might explore the lake.
The expedition continued to follow the course of the Bear River northward until they reached what is today Soda Springs, Idaho. Near this location, on August 25, instead of proceeding on towards Fort Hall (near Pocatello, Idaho), Frémont handpicked seven men and left the Oregon Trail to explore the inland sea. The rest of the company went on to Fort Hall to await their commander’s return.
Following the Bear River southward, Frémont’s party camped just west of where Preston, Idaho, is today, then proceeded west until coming to the Malad River, which he called the Roseaux, or Reed River. Following the Malad southward, the expedition crossed the forty-second parallel into Utah and on September 1 camped three hundred yards above where the Malad flows into the Bear. Two days later they reached the Bear River delta (what is today the Bear River Migratory Bird Refuge). The company then proceeded on a southward course east of the Great Salt Lake, somewhat parallel to the Wasatch Mountain range, before reaching the Weber River on September 5. Although they had been on the perimeter of the Great Salt Lake for several days, the men still had not seen the lake because they had traveled in the low-lying areas, where much of the view had been obscured by plant life. Leaving their camp on the Weber River on the morning of September 6, Frémont directed his men to a butte (now called Little Mountain), where for the first time the company experienced their first full view of the great inland sea.
On September 9, using an eighteen-foot inflatable rubber boat loaded with provisions, fresh water, blankets, and scientific equipment and instruments, Lieutenant Frémont, Charles Preuss, Kit Carson, Baptiste Bernier, and Basil Lajunesse paddled out onto the lake and steered a course to a large island some five miles distant. Reaching the desolate island, they spent the better part of two days exploring and making scientific measurements and calculations. Frémont named the land mass “Disappointment Island,” because he had expected to find game and thick vegetation there but did not. The island has since been renamed Fremont Island in honor of the explorer (figure 1). 
Figure 1. Frémont and Preuss, map of the Great Salt Lake.
On September 10, Frémont and his men left the island and paddled back to the mainland to begin the return trip to Fort Hall, where the main body of men in the expedition had been waiting. Frémont recorded that the party returned “by nearly the same route which we had traveled in coming to the lake.” On September 15, four days after having departed from the lake’s shores, the expedition crossed the current northern Utah border into Idaho and arrived at Fort Hall on September 19. All total, Frémont spent approximately two weeks (September 1–15) within the present confines of northern Utah (figure 2).

The expedition departed Fort Hall on September 22 and followed the Snake River until reaching Fort Boise, situated on the junction of the Snake and Boise Rivers (the present border of Idaho and Oregon). About two weeks later, after proceeding on an overland journey through the Blue Mountains of Oregon, the government expedition arrived at Marcus Whitman’s mission near Walla Walla, Washington. After Frémont reached the Columbia River, his next destination was The Dalles, where his expedition arrived on November 5. From here, the lieutenant and a handful of men canoed down the Columbia to Fort Vancouver, where they arrived on November 8. With his arrival at Fort Vancouver, Frémont essentially fulfilled or completed the mission of the expedition, and from here he could have simply retraced his steps and returned to the east. However, having no intention to retrace his steps, he set out to conduct further explorations to the south.
At The Dalles, Frémont traveled due south along the eastern slope of the Cascade Mountains. Near Klamath Lake, the expedition headed south-southeast into northwestern Nevada. After making almost a complete circle along the eastern slope of the Sierra Nevada in central Nevada and California, Frémont finally chose to cross the formidable mountains slightly south of Lake Tahoe. It took the expedition from the middle of January to the first part of the month of March to travel through the Sierra Nevada to Sutter’s Fort. Leaving the fort during the latter part of March, Frémont journeyed through the Sacramento and San Joaquin Valleys. Upon striking the Mojave River, the explorer struck the Old Spanish Trail, then turned east en route to the Utah region once again.
On approximately May 10, 1844, while following the Virgin River upstream in the extreme southwest portion of present-day Utah, Frémont’s company entered the state’s confines a second time. Near what is today St. George, Frémont recorded that his men immediately began to display a more lively spirit because of the noticeable change of the country’s surroundings. The greener terrain of southern Utah was a welcome sight after their having traveled for several weeks through the dry territory of southeastern California and southern Nevada. “We seem to have entered a different climate,” the commander wrote. “The country is no longer so distressingly desolate.”
By May 12, the company had advanced northward up the Santa Clara River into a pastoral area in low-lying mountains, which, in 1857, became the scene of the bloody massacre of emigrants passing through Utah on their way to California. Commonly known as Mountain Meadows, the area was the last resting spot for travelers on the Old Spanish Trail before proceeding across what is now the southern Nevada desert region. Although Frémont was traveling in the opposite direction, the meadows also served his expedition’s needs as a place for rest and recuperation. He wrote:
We found here an extensive meadow, rich in bunch grass, and fresh with numerous springs of clear water, all refreshing and delightful to look upon. It was, in fact, las Vegas de Santa Clara, which had been so long present to us as the terminating point of the desert, and where the annual caravan from California to New Mexico halted and recruited for some weeks. It was a very suitable place to recover from the fatigue and exhaustion of a month’s suffering in the hot and sterile desert. The meadow was about a mile wide, and some ten miles long, bordered by grassy hills and mountains.
Leaving the meadows, Frémont descended into the broad Escalante Valley. Viewing the vast expanse to the west, the explorer realized that the chain of mountains to the east—the western rim of the southern Colorado Plateau (along with the Wasatch Range farther north)—formed the east rim of a large geographic basin that had no outlet to the sea. Frémont had earlier concluded that the Sierra Nevada range formed the basin’s western boundary. In his Report, Frémont appropriately designated this region the “Great Basin” (figure 3).
Figure 3. John C. Frémont and Charles Preuss, Map of Oregon and Upper California (1848), showing the Great Basin region identified by Frémont following his 1843–44 expedition. The arrows point to what Frémont incorrectly presumed were a northern and a southern mountain range that enclosed the Great Basin region.
With the arrival of the expedition at the Sevier River on May 23, Frémont’s party reached the last major river crossing before proceeding on to Utah Valley. Dominguez and Escalante had named the Sevier River and Sevier Lake on their expedition in 1776, and the explorer, being well aware of the names given to these two water sources by the Spanish Fathers, referred to them as such in his Report as well as on his 1845 map.
On the morning of May 25, two days after crossing the Sevier, the expedition arrived in Utah Valley, where they camped for two days in two separate encampments (figure 4). During their time in the valley, the company encountered numerous Ute Indians near the lake, and one group provided the company with fresh fish, which Frémont called “salmon trout.” The lieutenant was especially impressed with the area’s fertility and the numerous streams that flowed into the lake. “The lake is bordered by a plain, where the soil is generally good, and in greater part fertile; watered by a delta of prettily timbered streams,” he wrote. “This would be an excellent locality for stock farms; it is generally covered with good bunch grass, and would abundantly produce the ordinary grains.”

On May 27, Frémont’s party exited Utah Valley through Spanish Fork Canyon. One week later they arrived at Fort Uinta (also called Fort Robidoux, after Antoine Robidoux) located on the Uinta River, where they stayed for two days. Leaving the fort on June 5, the company traveled some twenty-five miles in a northeast direction and camped on Ashley Creek. Two days later, on the afternoon of June 7, the expedition crossed the Green River and arrived at Brown’s hole near the present-day Utah-Colorado border. In total, Frémont spent some forty-three days within the confines of Utah during the 1843–44 expedition—fifteen days exploring the northern portion of Utah in 1843 (September 1–15) and twenty-eight days traversing the southern, central, and eastern regions in 1844 (May 10–June 7; figure 5).

After leaving the Utah region, once again Frémont was not content to return east over familiar territory. From Brown’s Hole he traversed the central Colorado region before arriving at Pueblo on June 28 and Bent’s Fort on June 30. Leaving Bent’s Fort five days later, Frémont followed the Arkansas River eastward until reaching the northern bend of the river (near Great Bend, Kansas). There, the expedition journeyed overland to the Smoky Hill River, then followed the Smoky to the Kansas River until they reached the Santa Fe Trail. By August 6, fourteen months after the expedition officially began, the commander and his weary men arrived in St. Louis.
Frémont’s 1842 and 1843–44 Expeditions and the Mormons in Illinois
Frémont’s writings about his 1842 expedition to South Pass and the Wind River Range in Wyoming were read by Mormons in Illinois 1843, when portions of the explorer’s narrative from his first expedition were published in the Nauvoo Neighbor in October of that year. John Taylor and Wilford Woodruff, coeditors of the Neighbor, did not indicate how they obtained the extracts from the expedition, or why they printed them, but newspaper editors often copied articles from other newspapers that circulated around the country. In early 1844 Joseph Smith obtained a printed copy of Frémont’s 1842 expedition courtesy of Illinois congressman Stephen A. Douglas from Washington, DC. In April, while Orson Hyde was in Washington, engaged in petitioning the government about matters concerning the Mormons and the possibilities of securing a place for the Church in the West, Hyde wrote to Church leaders in Illinois and informed them of the following:
Judge Douglass has given me a map of Oregon, and also a Report on an exploration of the Country lying between the Missouri River and the rocky Mountains on the line of
line of <the> Kansas, and great Platte Rivers: by Lieut. J. C. Fremont of the Corps of topographical Engineers. On receiving it, I expressed a wish that Mr. Smith [Joseph Smith] could see it. Judge D. [Douglas] says it is a public document, and I will frank it to him. I accepted his offer, and the book will be forth coming to him. The people are so eager for it here that they have stole it out of the Library. The author is Mr. [Thomas Hart] Benton’s son-in-law. Judge D. [Douglas] borrowed it of Mr. B. [Benton]. I was not to tell any one in this city where I got it.
The book is a most valuable document to any one contemplating a journey to Oregon.
It is important to note that the narrative and map of Frémont’s 1842 expedition to South Pass arrived in Nauvoo before the death of Joseph Smith. Mosiah Hancock said he heard Smith speak to the Nauvoo Legion just before his death, and pointing to Frémont’s map, he said: “I will show you the travels of this people. . . . Here you will make a place for the winter; and here you will travel west until you come to the valley of the Great Salt Lake.” Even though Frémont did not come into Utah on his first expedition in 1842, it is significant that Joseph Smith and the Mormons were interested in Frémont’s western travels before they made any definitive plans for the western exodus.
Brigham Young and the Quorum of the Twelve Study Fremont’s Report
Upon completion of his 1843–44 expedition in August 1844 in St. Louis, Frémont returned to Washington, DC, to report to government leaders and to prepare for publication the account of his travels in the Rocky Mountains and the Pacific. By March 1, 1845, Frémont’s narrative of his second expedition, now ready for publication, led Congress to authorize the printing of ten thousand copies of a report detailing the 1842 and 1843–44 expeditions.
Importantly, reports about Fremont’s second expedition to the West were printed in the Nauvoo Neighbor even before the completion of the published volume in Washington, DC. In late January 1845, the Neighbor published a brief sketch of Frémont’s 1843–44 expedition, including his reaching the Great Salt Lake and Utah Lake (spelled “Euta”). In March, less than two months later, another article about the 1843–44 expedition appeared in the Neighbor with notably more space devoted to a description of the Utah region. In September 1845, three issues of the Nauvoo Neighbor (September 10, 17, and 24) included information on both the 1842 and 1843–44 expeditions. However, by this time, the publishing of the ten thousand bound copies of Frémont’s Report had been completed and released for public sale. This is significant, since all three of the September 1845 issues of the Nauvoo Neighbor included actual excerpts from the Report, not merely summarized articles, clear evidence that by this time, the editors of the Neighbor were reprinting Frémont’s narrative from the published Report. For example, the September 17 issue of the Neighbor included actual extracts from Frémont’s Report under the dates of August 21, 23, and 25, 1843—the period of time when the explorer was following the course of the Bear River into the Utah region. Perhaps more significantly, the September 24 issue of the Nauvoo Neighbor (the last issue which contained information about Frémont), included some four and a half columns filled of extracts from the Report under the dates of August 29–30, 1843, and September 6, 8–9, 1843, all dates in which Frémont was in the vicinity of Utah and the Great Salt Lake. The closing paragraphs in the September 17 issue of the Neighbor perhaps reveal the extent to which the Mormons were interested in the Great Basin region by that time:
The Great Salt Lake, one of the wonders of nature, and perhaps without rival in the world, (being a saturated solution of salt, of a hundred miles in diameter,) is for the first time revealed to our view, by one who has surveyed its shores and navigated its waters.—The Bear River Valley, with its rich bottoms, fine grass, walled up mountains, hot springs, mineral springs, soda fountains, volcanic rock, volcanic crater, and saline effervescences, and four thousand five hundred feet above the sea, is for the first time described. . . .
Of the Geographical discoveries and descriptions, the most striking is that of the Great Basin or vast interior plane [sic] which lies between the Sierra Nevada and Rocky Mountains east and west, and between the Blue mountains and the Wahsatch [sic] on the South, and embracing and area of five or six hundred miles in diameter. The elevation of the Sierra Nevada being more lofty than the Rocky Mountains accounts for the formation of the Great Basin, as Lieutenant Frémont called it, and of which he is the first to announce its existence to the world. A basin which may hold such a kingdom as France, and which has for its rim a circle of mountains, whose summits penetrate the regions of eternal snow, is certainly a new and grand object to be revealed.
By late August Mormon leaders had proposed that the main place of Mormon settlement would possibly be in the vicinity of Utah Lake in present-day Utah County. However, those plans were quickly modified. On September 9, a general council resolved to send “a company of 1500 men be selected to go to the Great Salt Lake Valley.”
Brigham Young and other Church leaders were intensely interested in Frémont’s Report and read from it frequently. For example, on December 20, 1845, members of the Quorum of the Twelve Apostles assembled in the attic room of the Nauvoo Temple, where they listened to Franklin D. Richards read from Frémont’s published narrative. Heber C. Kimball wrote a few more details concerning the reading: “Pres. Young having slept in the Temple last night was early at his post, and dictating in relation to the business of the day. And arranging the workmen in order, . . . after which he listened to a reading from Capt. Fremont’s journal by Franklin D. Richards in the east room. . . . Amasa Lyman came in during the reading, also Heber C. Kimball, at a quarter to 10. The reading was finished at 10 o’clock.” A week and a half later, on December 29, 1845, William Clayton reported that Young “spent near an hour reading Capt. Fremont’s Narrative, after which he retired for the night.”
It is interesting to note that Brigham Young was misled in one particular way by Frémont’s reporting. After reading the Report, the Mormon leader was of the opinion that the Great Salt Lake and Utah Lake were in fact one lake. When Frémont was in the vicinity of Utah Lake for two days during the latter part of the month of May 1844, he explored only the southern portion of Utah Valley before heading east through Spanish Fork Canyon. Since he did not explore the region between Utah Lake and the Great Salt Lake, the explorer-scientist made the following incorrect conclusion about the relationship of the two bodies of water:
It [Utah Lake] is a lake of note in this country, under the dominion of the Utahs, who resort to it for fish. Its greatest breadth is about 15 miles, stretching far to the north, narrowing as it goes, and connecting with the Great Salt Lake. This is the report, and which I believe to be correct; but it [Utah Lake] is fresh water, while the other [the Great Salt Lake] is not only salt; but a saturated solution of salt; and here is a problem which requires to be solved. . . . The Utah [Lake] is the southern limb of the Great Salt Lake; and this we have seen that remarkable sheet of water both at its northern and southern extremity.
Frémont’s conclusions about the two lakes were definitely inaccurate, and it is easy to see how Brigham Young was misled by the explorer’s reporting.
Some years after the Mormons settled in the Great Salt Lake Valley, Eli Perkins interviewed Brigham Young. During the course of the interview, Perkins recorded that when Brigham Young read Frémont’s Report, the Mormon leader came away with the idea that the Great Salt Lake was composed of both salt and fresh water. A portion of the Perkins-Young interview, which appeared in the New York Times, reads as follows:
“How came you to think of Utah?” I asked.
“Well, we had read an account of Gen. Fremont’s travels—how he found a large salt lake in the interior of our continent, in the middle of a fertile plain. We read the account of his rowing to an island in the centre of the lake in an India-rubber boat, and how the south end of the lake was fresh and the north salt.”
“But the south end of Salt Lake is not fresh, is it?” I asked.
“No; Fremont made a mistake. In going to the south of Salt Lake he struck Utah Lake, another lake, and thought it was a continuation of the same lake.”
Figure 6. John C. Frémont and Charles Preuss, Map of an Exploring Expedition to the Rocky Mountains in the Years 1842 and to Oregon & North California in the Years 1843–44 (1845). Upon completing his survey of the southern portion of the Utah Valley in 1844, Frémont incorrectly assumed that Utah Lake and the Great Salt Lake were one body of water connected by a narrow channel (see arrow).
When Frémont read the Perkins-Young interview in the Times, the explorer responded with his own explanation of the alleged discrepancy about the two lakes and insisted that he did not err in his reporting and that Brigham Young was in error. However, from his description given in the Report, it is clear that in 1844 Frémont did not understand the true relationship of the two lakes. Two pieces of evidence support this conclusion. First, on the map of his 1842 and 1843–44 expeditions, Frémont and cartographer Charles Preuss joined Utah Lake and the Great Salt Lake with a rather large narrow channel, essentially making them one lake (figure 6). Second, in his expedition through Utah the following year (1845), Frémont spent some two weeks in the vicinity of both Utah Lake and the Great Salt Lake. On this occasion he investigated the northern shore of Utah Lake and clearly saw what is today the Jordan River flowing some twenty-five miles northward into the Great Salt Lake. It was at this time that he clearly understood the relationship between the two bodies of water. This is evident from Frémont’s 1848 map, on which he made the necessary correction and showed the two lakes being connected by the Jordan River (figure 7).
Figure 7. John C. Frémont and Charles Preuss, Map of Oregon and Upper California (1848). While en route to California in 1845, Frémont passed through the northern Utah region, bringing him once again in the vicinity of Utah Lake and the Great Salt Lake. On this occasion, he observed firsthand that the two lakes were actually not connected by a narrow channel but that Utah Lake had an outlet—the Jordan River (titled the "Utah" River by Frémont on his map)—which flowed north and emptied into the Great Salt Lake (see arrow).
Excerpts of Fremont’s Report Published in the Millennial Star
By 1846, converts to The Church of Jesus Christ of Latter-day Saints living in the British Isles could also read about Fremont’s adventures in the American West and more specifically the Great Basin region. When Congress ordered that the Report be printed, no copyright was attached to the document, and publishers were free to reproduce the Report without restriction, resulting in numerous publishing companies reprinting the document under various titles. In 1846, for example, Wiley Putnam Publishers of London completed a printing of Frémont’s narrative. Using the Wiley Putnam edition, Orson Hyde, editor of the Millennial Star, a newspaper published in Liverpool, printed excerpts of Frémont’s 1843–44 expedition. On March 1, 1846, the first passages of Frémont’s Report appeared in the Millennial Star, and accounts continued to appear in the newspaper until October 15, 1846. Perhaps Hyde hoped that by publishing Frémont’s favorable descriptions of the newly proposed Mormon place of settlement, British Mormons would be more inclined to gather to Zion.
Mormon Leaders Acquire Frémont’s 1845 Map
Although the Mormons obtained a copy of Frémont’s narrative of the 1842 expedition by early 1844 and the explorer’s published Report of the 1842 and 1843–44 expeditions by September 1845, Church leaders apparently did not obtain Fremont’s map of the “combined” expeditions until March 27, 1847, just a few days prior to leaving Winter Quarters for the trek west. Brigham Young noted that on this date he received a copy of Fremont’s Map of an Exploring Expedition to the Rocky Mountains in the Years 1842 and to Oregon & North California in the Years 1843–44 (published 1845) from Missouri Senator David R. Atchison, and former legal counsel to the Mormons in Missouri. Upon completion of the second expedition, Frémont and his cartographer, Charles Preuss, combined to produce a large lithographed map of both the 1842 and 1843–44 expeditions. Like the Report, the map was also completed in 1845, but it was published separately. This explains how the Saints could have obtained a copy of the Report in 1845, but not the large detailed map. There can be little doubt that the map given by Atchison to Mormon leaders at Winter Quarters was Frémont’s 1845 map. On April 4, 1847, eight days after receiving it, Young recorded: “T [Thomas] Bullock made a sketch of Capt. Fremont’s topographical map of [the] road to Oregon for the use of the Pioneers.”

In an act of interest and kindness, in early 1847 Atchison sent a copy of John C. Frémont’s Map of an Exploring Expedition to the Rocky Mountains in the Years 1842 and to Oregon & North California in the Years 1843–44 to Mormon leaders at Winter Quarters to assist them in their journey west.

It appears that the main contribution Mormon leaders obtained from Frémont’s Report was not necessarily to assist them in knowing the route which they were to travel to the valley of the Great Salt Lake, although the Report and maps certainly gave them assistance. Of greater importance and concern was learning about the agricultural and geographic characteristics of the region in order to assess whether the region would meet the needs of the vast number of people they envisioned would settle in the region. Assessments by Frémont, such as the following, must have played an important part in the decision by the Church’s leadership to settle in the vicinity of the Great Salt Lake:
Taking leave at this point of the water of the Bear River, and of the geographical basin which encloses the system of rivers and creeks which belong to the Great Salt Lake, and which so richly deserves a future and detailed and ample exploration, I can say of it, in general terms, that the bottoms of this river, (Bear) and some of the creeks which I saw, form a natural resting and recruiting station for travelers, now, and in all time to come. The bottoms are extensive; water excellent; timber sufficient; the soil good, and well adapted to the grains and grasses to such an elevated region.
I can only say, in general and comparative terms, that, in that branch of agriculture which implies the cultivation of grains and staple crops, it would be inferior to the Atlantic States, though many parts are superior for wheat; while in the rearing of flocks and herd it would claim a high price. Its grazing capabilities are great; and even in the indigenous grass not there, and element of individual and national wealth may be found.
In 1848, when he presented his Geographical Memoir Upon Upper California to the United States Senate, Frémont was no doubt pleased to report to the lawmakers that the Mormon people had settled in the Great Basin, an area he promoted as being rich in natural resources. And although he reported that “the general character of the Great Basin was that of a desert,” he also added, “but with great expectations, there being many parts of it very fit for the residence of a civilized people; and of these parts, the Mormons have lately established themselves in one of the largest and the best.”
Frémont’s published narratives and maps from his first and second expeditions had a profound impact on the Mormons in Illinois. Mormon leaders were particularly interested in the information he provided about the geographical elements, and the agricultural and economic potential of the Bear River area, the Salt Lake Valley, and the Great Basin in general. The explorer’s assessment of this geographic region played a significant part in the decision by Mormon leaders in Illinois in their selection of northern Utah as the main place of Mormon settlement in the West.

Featured on the granite base and tower are a number of bronze-cast figures created by the renowned Latter-day Saint sculptor Mahonri M. Young (grandson of Brigham Young). Most notable are the large statues of Mormon leaders Brigham Young, Heber C. Kimball, and Wilford Woodruff, who stand atop the centerpiece while gazing to the west over the Salt Lake Valley. In addition, nearly twenty other figures are situated around the monument’s base, including one representing John C. Frémont. A plaque, placed in front, provides a fitting tribute highlighting the contributions of the explorer to the Utah region and his influence upon the Mormon populace:
John C. Fremont
Pathfinder, explorer, soldier, statesman. Led five significant exploring and scientific expeditions to the West, 1842–54, three of which traversed the Great Basin to California. Conducted the first scientific exploration of the Great Salt Lake in 1843 and was the first to traverse the treacherous Great Salt Lake Desert directly westward from [the] Great Salt Lake to the site of modern Elko, Nevada. His report and map published in 1845 were invaluable to the Mormon pioneers in their westward journey.

Frémont’s western expeditions is Donald Jackson and Mary Lee Spence, eds., The Expeditions of John Charles Frémont, 3 vols. (Urbana: University of Illinois Press, 1970–84).

Frémont of the Topographical Engineers, Under the Order of Col. J. J. Abert, Chief of the Topographical Bureau (Washington, DC: Gales and Seaton, 1845), 132 (hereafter cited as Frémont, Report. The Report was initially published as a Senate document (28th Congress, 2nd session, Senate executive document 174, serial 461). No copyright was issued for the Report, and numerous publishers reprinted the document under various titles. A memorial marker has been erected near Evanston, Wyoming, commemorating the site where the expedition encamped on the Bear River.

 Theodore Talbot, one of the members of the expedition who waited at Fort Hall while the smaller expeditionary force explored the lake, recorded that Frémont’s company arrived at Fort Hall on September 18. See Charles Carey, ed., The Journals of Theodore Talbot, 1843 and 1849–52, with the Frémont Expedition of 1843 and with the First Military Company in the Oregon Territory, 1849–52 (Portland: Metropolitan Press, 1931), 50. Apparently Frémont arrived back at Fort Hall late in the day of September 18, but he did not meet with the men from his company who had remained behind at the fort until the next day. See Frémont, Report, 162.

 Frémont, Report, 272. The map Frémont and his cartographer, Charles Preuss, produced following the 1842 and 1843–44 expeditions shows relatively little information about the interior of the Great Basin, but it is obvious that Frémont clearly understood the relationship of the Wasatch and southern Colorado Plateau with that of the Sierra Nevada in forming the eastern and western boundaries of the Great Basin. However, in 1848, when the two men combined to produce yet another topographical map of the western U.S. region, they inaccurately placed two mountain ranges running east and west at both the northern and southern extremities of the basin. Frémont was obviously under the assumption that since the area had no outlet to the sea, and since the basin clearly had an eastern and western boundary, it must also have been bordered by a northern and a southern mountain range. In defining the Great Basin, Frémont also dispelled a myth that had persisted for decades—that a river flowed from the Rockies to the Pacific. This river, usually referred to as Buenaventura, began to appear on maps following the 1776 Dominguez-Escalante expedition. However, following Frémont’s 1843–44 expedition, the mythical river virtually disappeared from maps.

 See “South Pass to Oregon,” Nauvoo Neighbor 1, no. 26 (October 25, 1843): 1. The account of Frémont’s 1842 expedition was first published as an independent document in 1843 under the title A Report of an Exploration of the Country Lying between the Missouri River and the Rocky Mountains, on the Line of the Kansas and Great Platte Rivers (Washington, DC: Printed by Order of the United States Senate, 1843). The document was later reprinted in 1845 along with the account of the 1843–44 expedition as part of Frémont’s Report.

B. H. Roberts, 2nd ed., rev., 7 vols. (Salt Lake City: Deseret Book, 1971), 6:375 (hereafter cited as History of the Church). Congressional members and government officials have been entitled to franking privileges or free postage service for government-related mail, which is probably why Douglas offered to cover the postage required to mail the copy of Fremont’s 1842 report to Joseph Smith. The fact that Hyde refers to Frémont as “Lieut. Fremont” supports the conclusion that the document Douglas sent to Joseph Smith at Nauvoo was the report of the 1842 Wind River expedition and not the report that included Frémont’s 1843–44 expedition, when he came into the Utah region. In the published report of the latter expedition, Frémont had acquired the title of captain.
 Mosiah Lyman Hancock, “The Life Story of Mosiah Lyman Hancock,” typescript, 28, L. Tom Perry Special Collections, Harold B. Lee Library, Brigham Young University, Provo, UT. It is important to note that Hancock would have only been ten years old at the time he said he heard Joseph Smith speak about the Latter-day Saints relocating to the Great Salt Lake Valley. In addition, Hancock’s narrative is a late reminiscence, which suggests that his information may not be entirely accurate. However, besides Hancock, a number of individuals recalled Joseph Smith stating on different occasions that the Latter-day Saints would eventually relocate to the West, and more specifically to the Rocky Mountains. Perhaps the statement most often attributed to the Mormon leader is the following, which appears in the Manuscript History of the Church under the date of August 6, 1842: “I prophecied that the Saints would continue to suffer much affliction and would be driven to the Rocky Mountains, many would apostatize, others would be put to death by our Persecutors, or lose their lives in consequence of exposure or disease, and some of you will live to go, and assist in making settlements and build cities and see the Saints become a mighty people in the midst of the Rocky Mountains.” Manuscript History of the Church, vol. D–1, 1362, CHL. The source appears to have come from a statement given by Anson Call. See History of the Church, 5:85n. For an analysis of the validity of the statement, see Davis Bitton, “Joseph Smith in the Mormon Folk Memory,” Restoration Studies I, ed. Maurice L. Draper and Clare D. Vlahos (Independence, MO: Herald Publishing, 1980), 85; and Lewis Clark Christian, “A Study of Mormon Knowledge of the American Far West Prior to the Exodus” (master’s thesis, Brigham Young University, 1972), 72–73. Historian Ronald K. Esplin gives additional evidence to show that even prior to 1842, Joseph Smith had conveyed to others the idea that the Latter-day Saints would eventually settle in Rocky Mountains. Esplin further demonstrates that beginning in early 1844, the Mormon leader began making more definitive plans to relocate the main body of the Saints in the West, which plans were eventually carried out by the Quorum of the Twelve Apostles. See Ronald K. Esplin, “A Place Prepared: Joseph, Brigham, and the Quest for Promised Refuge in the West,” Journal of Mormon History 9 (1982): 85–111; see also Christian, “A Study of Mormon Knowledge of the American Far West Prior to the Exodus,” 78–87.
 John Charles Frémont, Memoirs of My Life (Chicago and New York: Bedford, Clarke and Company, 1887), 415. Frémont intended Memoirs to be a two-volume narrative of his life; however, only volume one was published. The volume covers the history of Frémont’s life through the year 1847. His wife, Jessie, attempted to chronicle the remaining forty-three years of her husband’s life in a manuscript she titled “Great Events during the Life of Major General John C. Fremont,” but the manuscript was never published.

Nearly the entire first page (six columns) of the September 17 issue is devoted to information regarding Frémont’s 1843–44 expedition. In prefacing the article, John Taylor, editor of the Neighbor, noted that the information was originally printed in the National Intelligencer, a daily newspaper published in Washington, DC, circulated widely throughout the United States.

Beginning in September 1845, excerpts from Frémont’s Report were printed by other Illinois newspaper editors. For example, reports about Frémont’s 1843–44 western expeditions appeared in successive issues of the Sangamo Journal published in Springfield, Illinois. See “Captain Fremont’s Report,” Sangamo Journal 14, no. 52 (September 18, 1845): 4; “Captain Fremont’s Report,” Sangamo Journal 15, no. 1 (September 25, 1845): 4; “Captain Fremont’s Report,” Sangamo Journal 15, no. 2 (October 2, 1845): 4; “Captain Fremont’s Second Exploring Expedition,” Sangamo Journal 15, no. 3 (October 9, 1845): 4; and “Captain Fremont’s Second Exploration Expedition, Sangamo Journal 15, no. 4 (October 16, 1845): 4.

 See Council to Addison Pratt, August 28, 1845, Brigham Young Papers, CHL. A portion of the letter is cited in Lewis Clark Christian, “Mormon Foreknowledge of the West,” BYU Studies 21, no. 4 (Fall 1981): 411. Christian presents substantial evidence to conclude that by early September 1845, Mormon leaders had made the decision to settle in the vicinity of the Great Salt Lake. See Christian, “Mormon Foreknowledge of the West,” 411–12; Christian, “A Study of Mormon Knowledge of the American Far West Prior to the Exodus,” 111; and Christian, “A Study of the Mormon Westward Migration between February 1846 and July 1847 with Emphasis on and Evaluation of the Factors that Led to the Mormons’ Choice of Salt Lake Valley as the Site of Their Initial Colony” (PhD diss., Brigham Young University, 1976), 34.

A portion of the interview was also included by Frémont in Memoirs of My Life, 415. In speaking to a congregation of Latter-day Saints in Brigham City, Utah, in 1865, George A. Smith, a member of the Quorum of the Twelve Apostles, “alluded to the explorations of John C. Fremont, who with men furnished to him, and at the expense of some $40,000 to the government, had made a wonderful discovery that the Great Salt Lake and Utah lake were one sheet of water, propounding the startling proposition, how the north end of the same lake could be salt and the south end fresh!” E.

 Elden J. Watson, ed., Manuscript History of Brigham Young, 1846–1847 (Salt Lake City: the Compiler, 1971), 542. Atchison was a longtime friend of the Mormons. Following the expulsion of the Mormons from Jackson County, Missouri, in late 1833, Atchison was one of several attorneys hired to help the displaced Mormons. As a general in the state militia during the years 1838–39, he vigorously sought to help secure the Saints their rights as citizens. It appears he still had sympathetic feelings for the Saints in his gesture of making sure Mormon leaders had a copy of Frémont’s 1845 map to assist them on their trek west.
