John Charles Fremont had an extremely varied life. Born in 1813, he would become a leader of western mapping expeditions, a major figure in the U.S. takeover of California (and returned to Washington, D.C. for court martial), a financial speculator, U.S. senator, the Republican Party's first presidential candidate, and a Civil War general.

While called "the Pathfinder," Fremont usually surveyed established routes.  Before the age of specialists, he served as chief scientist with roles: astronomer, botanist, geologist, and meteorologist.  He saw more of the west than others of his generation, and his expedition reports, written with his wife, Jessie Benton Fremont, described the west to an expanding U.S. population. The report of his 1842 expedition caught the nation in the midst of "Oregon fever".  His report of the 1843-44 expedition contained detailed maps of the Oregon Trail.  Fremont named many locations, including the Humboldt River, and the Golden Gate, and in turn others used his name for counties, cities, mountains, and rivers.

Fremont's five major expeditions include the following:

bulletIn 1842, he led an expedition that mapped much of the Oregon Trail route to South Pass, and then proceeded on to the Wind River Range, and then returned to Westport, Missouri.
bulletIn 1843-44, he again crossed South Pass and continued on much of the Oregon Trail route to the Dalles Mission on the Columbia River. He then headed south to the eastside of the Sierra Nevada Mountains, and then made a winter crossing of Carson Pass in deep snow to reach Sutter's Fort near Sacramento, California. He went down the central valley of California, and turned east, returning through present-day Nevada, Utah, Colorado, and Kansas to Westport.
bulletIn 1845, he headed west out of Westport, and traveled down the Humboldt River, later a part of the California Trail, and crossed the Sierra Nevada at what would be later called Donner Pass.
bulletHis 1848-9 expedition sought to locate a route across the Rocky Mountains that could be used all year. They found disaster in the winter snow of the southern Rockies.
bulletIn 1853-54, he followed the route of his previous expedition, with some corrections, and was able to continue to California. Solomon Nunes Carvalho provided the first western expedition with photographic documentation.

Late in their lives Jessie Benton Fremont wrote to her husband, "All your campfires have become cities." In 1887, Collis Huntington, President of the Central and Southern Pacific railroads, told Fremont: "...our road goes over your buried campfires and climbs many a grade you jogged over on a mule..."  Fremont died in 1890.

Arctic explorer Adolphus Greely summarized Fremont's contributions in 1893:  "In few instances did it fall to Fremont's lot to first explore any section of the country, but it was his good fortune, as it was his intent, to first contribute systematic, extended, and reliable data as to climate, elevation, physical condition, and geographical positions."

Current image galleries do not yet completely cover any of his expeditions.
