ion of the river Des Moines, then on the
Western frontier. In 1841 he projected his first trans-continental
expedition, and left Washington May 2, 1842, and accomplished the object
of his trip, examined the South Pass, explored the Wind River mountains,
ascended in August, the highest peak of that range, now known as
Fremont's Peak, and returned, after an absence of four months. His
report of the expedition attracted great attention in the United States
and abroad. Fremont began to plan another and a second expedition. He
determined to extend his explorations across the continent; and in May,
1843, commenced his journey with thirty-nine men, and September 6, after
traveling over 1,700 miles, arrived at the Great Salt Lake; there made
some important discoveries, and then pushed on to the upper Columbia,
down whose valley he proceeded to Fort Vancouver, near its mouth. On
Nov. 10, he set out to return East, selecting a southeasterly course,
leading from the lower part of the Columbia to the upper Colorado,
through an almost unknown region, crossed by high and rugged mountains.
He and his party suffered incredible hardships in crossing from the
Great Basin to Sutter's Fort on the Sacramento; started from there March
24, proceeded southward, skirted the western base of the Sierra Nevada,
crossed that range through a gap, entered the Great Basin; again visited
the Great Salt Lake, from which they returned through the South Pass to
Kansas, in July, 1844, after an absence of fourteen months. In the
spring of 1845 Fremont set out on a third expedition to explore the
Great Basin and the maritime region of Oregon and California; spent the
summer examining the headwaters of the rivers whose springs are in the
grand divide of the continent; in October camped on the shores of the
Great Salt Lake: proceeded to explore the Sierra Nevada, which he again
crossed in the dead of winter; made his way into the Valley of the San
Joaquin; obtained permission, at Monterey, from the Mexican authorities
there, to proceed with his expedition, which permission was almost
immediately revoked, and Fremont peremptorily ordered to leave the
country without delay, but he refused, and a collision was imminent, but
was averted, and Fremont proceeded toward San Joaquin. Near Tlamath
Lake, Fremont met, May 9, 1846, a party in search of him, with
dispatches from Washington, ordering him to watch over the interests of
the United States in California, as there
