This 30-square-mile area was a focal point for the discovery of gold in 1842 and the resultant 1867 gold rush that settled this part of Wyoming. By 1868, about 1,500 people lived in the District towns of South Pass and Atlantic City, but by 1872 the boom was over and the area was all but abandoned. BLM maintains 2 campgrounds and the ghost town of Miner's Delight in the area. Other attractions in the vicinity are the South Pass City State Historic site, the Wild Iris world-class rock-climbing site, remnants of five National Historic Trails (the Continental Divide, Oregon, Mormon Pioneer, California, and Pony Express Trails), and a Volksmarch Trail.
