Confederated Tribes of the Umatilla Indian Reservation

Generous in spirit and nature, the Cayuse, Umatilla and Walla Walla tribes were documented in the Lewis and Clark journals to have greeted and assisted the travelers as they passed through on their way west. 

Some 40 years later, the Oregon Trail cut through the heart of the tribes’ homelands, which stretched from the pine- and fir- forested Blue Mountains west to the Columbia River lowlands, and north beyond Washington’s Walla Walla Valley.

The Walla Walla and Umatilla are river peoples who lived along the Yakama, Umatilla and Walla Walla rivers and their confluences with the Columbia. The Cayuse lived along upper tributary valleys and in the Blue Mountains. They were known far and wide for their equestrian skills and for selectively breeding large herds of Cayuse horses, a stout, swift and agile breed well-suited for the steep and rocky terrain. All three tribes moved in a seasonal cycle, from sheltered winter villages to fishing sites to hunting, celebration and trading camps, sustained primarily by salmon, roots, berries, deer and elk.
