Umatilla River worlds: seasonal work and Tamástslikt public history

Reviewed community and place names are preserved where supported; no otherwise unknown ancient self-designation is invented.

CTUIR's history places river foods, seasonal work and wider connections within its own account, not a uniform nomadic stereotype. Tamástslikt's exhibitions explicitly address past, present and future; this is a living institution rather than a substitute ancient settlement.

Public community-history and seasonal-landscape context Pre-1800 seasonal and river histories; later governance and heritage institutions separately dated CTUIR public history, Tamástslikt interpretation and First Foods institutional policy Pendleton, Oregon, United States (orientation only): approximate public-town or distant institutional orientation, not an excavation, burial, sacred-site, cave-entrance, private compound or vulnerable-deposit location; never a territorial, ethnic, linguistic, cultural, political, religious, sovereignty, hunting, gathering, farming, fishing, water-rights or route boundary. The orientation may be far from the archaeological context. No access, collecting, fishing or travel permission is implied.
Overview

Caves, wetlands, households, rivers, and the evidence

Basin, plateau, lake, river, and neighboring connections

Pendleton, Oregon, United States is a modern orientation, not an ancient capital or boundary. Cayuse, Umatilla and Walla Walla histories are distinct; the modern Confederated Tribes government must not be projected onto every earlier household.

Political organization and community scale

Cayuse, Umatilla and Walla Walla histories are distinct; the modern Confederated Tribes government must not be projected onto every earlier household. Tamástslikt is a living institutional reference, not an excavated ancient capital; published public history does not authorize retelling restricted stories or determine recognition and membership.

Later transformation, living heritage, and modern reception

Living communities and heritage institutions retain their own authority; this atlas cannot establish identity, ancestry, descent, recognition or membership. Cayuse, Umatilla and Walla Walla language histories are not interchangeable; only public institutional material is summarized. Events after 1800 CE and modern research, reconstruction and stewardship are dated separately from the main historical context.

Multiple livelihoods CTUIR's history places river foods, seasonal work and wider connections within its own account, not a uniform nomadic stereotype.
