Lander is a city in Wyoming, United States, and the county seat of Fremont County. Named for transcontinental explorer Frederick W. Lander, Lander is located in central Wyoming, along the Middle Fork of the Popo Agie River. A tourism center with several guest ranches nearby, Lander is located just south of the Wind River Indian Reservation. The population was 7,487 at the 2010 census.
Lander was known as Pushroot, Old Camp Brown, and Fort Augur prior to its current name. The name Lander was choosen to honor General Frederick W. Lander, a famous transcontinental explorer who surveyed the Oregon Trail's Lander Cutoff.
The land where the town is now located was part of the Wind River Indian Reservation designated by the Fort Bridger Treay in 1868. However, by the early 1870s it had become apparent to the U.S. Government that most of the mineral rich and fertile land east of the Wind River Mountains was on the reservation. There were also reports of white settlers illegally living on the reservation north of Miner's Delight. As a result, in 1872 Congress authorized a delegation to meet with the elders of the Shoshone, including Chief Washakie to neogotiate the trade or purchase of lands south of the North Fork of the Popo Agie River. After several meetings at Camp Stambaugh in the summer of 1872, on September 26 of that year, the Shoshone agreed to sell the southern part of the reservation to the U.S. for $25,000, $5,000 in stock cattle and a five-year annual salary of $500 to Chief Washakie.
