Hell's Half Acre, Geological formation in Natrona County, Wyoming.
The formation spans 320 acres of land, featuring deep ravines, caves, and eroded earth formations shaped by natural processes over time.
Early settlers named this location after a cowhand mistook the area for another site known for its alkali deposits and bogs.
Native American tribes utilized the natural features of the area by directing bison herds through the ravines during their hunting expeditions.
Located 40 miles west of Casper on Highway 20/26, the site includes a gravel parking area and interpretive signs for visitors.
The geological formation gained international recognition when it served as the filming location for planet Klendathu in the movie Starship Troopers.
