Fort Bridger

Fort Bridger was originally a 19th-century fur trading outpost established in 1842, on Blacks Fork of the Green River, in what is now Uinta County, Wyoming, United States. It became a vital resupply point for wagon trains on the Oregon Trail, California Trail, and Mormon Trail. The Army established a military post here in 1858 during the Utah War, until it was finally closed in 1890. A small town, Fort Bridger, Wyoming, remains near the fort and takes its name from it.
