Tamástslikt Cultural Institute
Cayuse, Umatilla, and Walla Walla people tell their own histories—from homeland and treaty pressure to persistence, adaptation, and sovereignty.

Artwork inspired by Lillian Pitt
Tamástslikt’s permanent experience is structured from the perspective of the Confederated Tribes of the Umatilla Indian Reservation. The narrative begins long before the Oregon Trail and continues past treaty making and allotment into contemporary governance, family, language, art, and economic life. Before leaving, do not stop at treaty or reservation history; follow sovereignty into the present; that deliberate comparison is more valuable than adding another room.
Follow the intended sequence rather than skipping to visually dramatic objects. Sound, first-person voice, landscape, and changing exhibitions make the institute different from a collection assembled about Native people elsewhere; the most important interpretive choice is who controls the story.
