It is the only Native American museum along the Oregon Trail. The institute is dedicated to the culture of the Cayuse, Umatilla, and Walla Walla tribes of Native Americans. The main permanent exhibition of the museum provides a history of the culture of three tribes, and of the reservation itself. The museum also has a second hall for temporary exhibitions of specific types of Native American art, craftwork, history, and folklore related to the tribes.
