Built by more than 100 volunteers over the course of two years, this modern, full-scale Chinookan plankhouse was built based on findings from the archaeological village site of Cathlapotle. The Plankhouse and the objects inside of it offer a tangible link to those who lived there and provide a unique site for the interpretation of the natural and cultural heritage preserved on the Refuge. 

The US Fish & Wildlife Service and the Friends of the Ridgefield National Wildlife Refuge partner with the Chinook Indian Nation to offer an accurate representation of Chinookan culture both past and present inside the Plankhouse.

The Plankhouse is open for inside exploration on Saturdays and Sundays from early May until early October, typically from 12pm-4pm, depending on volunteer availability. Check with the Friends of Ridgefield National Wildlife Refuge for more information.
