Nation / Tribe
Cayuse
The Cayuse were a small but influential nation who inhabited the plateaus and river valleys of the Blue Mountains region in present-day northeastern Oregon and southeastern Washington. Though Sahaptian in cultural affiliation, they spoke a language isolate (Cayuse) and were renowned horsemen who had amassed large herds, making them powerful participants in regional trade and warfare. The Corps of Discovery passed through Cayuse territory in October 1805 on the outbound journey and again in the spring of 1806 on the return, though direct interactions were limited compared to their more extensive contact with neighboring Nez Perce and Walla Walla peoples.
