"Blackfeet warriors find evidence of intrusion by white men: a prospector’s gold pan and other debris carelessly left behind in a shallow stream. The Blackfeet were among the most implacable in their enmity toward white trespassers, first the beaver trappers and later the prospectors. And for good reason. Blackfeet had only to look at their neighbors, the Sioux and Cheyenne, where the discovery of gold in the treaty-protected Black Hills led to the final, crushing military campaigns against them." - Howard Terpning
