Fremont County was created in 1884. It is the historical home of the Wind River Indian Reservation, home of the Shoshone and Arapaho tribes of Native Americans. It included Park, Big Horn, and Hot Springs counties until 1890 when they split. It was named for General John Charles Fremont, who was a surveyor and explorer searching for a route to the Pacific ocean in 1842. His group of 20 men were guided by Kit Carson and Enos, a Shoshone Indian.
South Pass, a break in the continental divide, is also located in Fremont county. Indians had been using the pass for centuries before Robert Stuart and his group were the first whites to cross the pass October 12, 1812. The first horse drawn wagons to cross the pass were lead by Captain Benjamin Bonneville in 1832. Gold was discovered here in 1842. The big boom came in 1867 when the Carissa mine (Named for Clarissa Whitney who is thought to be the first white child born in Wyoming), Miner Delight, and Burr mines were discovered, producing millions of dollars in gold.
