Tamástslikt Cultural Institute tells the story of three American Indian Tribes, the Cayuse, Umatilla and Walla Walla, who for more than 10,000 years inhabited the Plateau region of the Pacific Northwest, U.S.A. They welcomed and assisted the Lewis and Clark Expedition in 1803-1806 and Clark documented the contacts in his journal. Some 40 years later, the Oregon Trail cut through the heart of their homelands.

Tamástslikt brings the story alive with a 14,000 square foot exhibit space that incorporates artifacts, photography, video and interactive multi-media experiences in world class exhibits. Events like gallery talks, topical speakers and a junior art competition allow visitors to immerse themselves into Tribal culture. The Museum Store sells American Indian art and crafts, as well as books, music, apparel, home decor, and Pendleton Woolen Mills exclusive blanket designs. Kinship Cafe serves Native-inspired lunch fare daily.
