Bighorn Basin

The largest cities in the basin include the Wyoming towns of Cody, Thermopolis, Worland, and Powell. Sugar beets, pinto beans, sunflowers, barley, oats, corn and alfalfa hay are grown on irrigated farms in the region. It is also used by elk, pronghorn and mule deer as a migration corridor.

History

The basin was explored by John Colter in 1807. Just west of Cody, he discovered geothermal features that were later popularly called "Colter's Hell". The region was later transversed by the Bridger Trail, which was blazed in 1864 by Jim Bridger to connect the Oregon Trail to the south with Montana. The route was an important alternative to the Bozeman Trail, which had crossed the Powder River Country, but had been closed to white settlers following Red Cloud's War. Around the turn of the 20th century the Bighorn Basin was settled by ranchers such as William "Buffalo Bill" Cody who founded the town of Cody and owned a great deal of land surrounding the Shoshone River. The Chicago, Burlington and Quincy Railroad extended a branch line to Cody in 1901 and ultimately built through the entire basin. In 1904, Cody helped to form the Shoshone project, the nation's first federal water development project to help irrigate the western portion of the basin. The project culminated in the construction of the Buffalo Bill Dam and reservoir. The wealth in the region also attracted outlaws. Butch Cassidy lived near Meeteetse for a while and was arrested at the insistence of local cattle baron Otto Franc and sent to the Wyoming State Penitentiary for horse theft. Following his release, he formed the Wild Bunch gang which operated from the Hole-in-the-Wall area southeast of the Bighorn Basin.

In 1942 one of the nation's ten Japanese American internment camps was located in Park County in the western part of the basin. The camp was named Heart Mountain Relocation Center, after nearby Heart Mountain. The camp operated until 1945, and at its peak detained over 10,000 internees.
