In August 1841, along the Snake River near the Wyoming border, sits the site of a skirmish between trappers and hostile Natives. Twenty-three trappers with a band of Shoshones withstood charges by five-hundred Cheyenne, Arapahoe, and Sioux. Even though the trappers held their own with the help of the Shoshones, they left the area shortly after. This battle gave a new name to Bastion Mountain, now known as Battle Mountain.
