Iisaxpuatahcheeaashe

Iisaxpuatahcheeaashe is the Apsaalooke name for the Bighorn River. Flowing north from the Wind River country, it passes through a deep canyon before continuing across the plains to join the Yellowstone. The name refers to bighorn sheep, and the river and its mountain tributaries form an important part of Apsaalooke country. The Little Bighorn joins it downstream of the canyon.
