ɬax̣awyam (welcome)

Since time immemorial Chinookan Peoples of the Lower Columbia River have tended to the oak woodlands, camas fields, and wapato patches of what we now call the Refuge, maintaining habitat for wildlife while supporting the lives of the people who called this place home. Based on the Chinookan village of Cathlapotle, the Plankhouse and the objects inside of it offer a tangible link to these original stewards and provides a unique site for the interpretation of our region's natural and cultural heritage.

Built in partnership with the Chinook Indian Nation, Portland State University, The U.S. Fish & Wildlife Service, and numerous other community partners and volunteers. This House serves as an education and interpretive center and is used by the Chinook Indian Nation for cultural events throughout the year. Visit the Cathlapotle Plankhouse and connect with local indigenous culture.
