Cathlapotle, settled approximately 450 years ago, was one of the largest Chinookan villages encountered by Lewis and Clark.
In October 1792, William Broughton produced the first European documentation of what is now believed to be Cathlapotle.
Lewis and Clark recorded visiting the “Quathlapotle Nation” on November 5, 1805. Seven canoes from the village accompanied them a few miles down the river. On March 29, 1806, Lewis and Clark visited Cathlapotle and traded with the Cathlapotle people for several hours. They camped nearby at a place now called Wapato Portage, near present day Carty Lake.
“…I observed on the Chanel which passes on the Stard Side of this Island a Short distance above its lower point is Situated a large village, the front of which occupies nearly ¼ of a mile fronting the Chanel, and closely Connected, I counted 14 houses in front here the river widens to about 1 ½ miles…” (Clark, November 5, 1805).

Fort Vancouver, the first Euro-American trading settlement in the Northwest, was established by the Hudson Bay Company in 1825 and served as a center for fur trade and other commerce. The Cathlapotle people and other native people of the Columbia River were frequent visitors to the fort.
The Carty Family claimed the land upon which Cathlapotle and the Wapato Portage site are situated in 1839 or 1840. The family used the land for farming, cattle grazing, hunting, fishing, and logging. They also built a homestead in the vicinity of the present day Plankhouse. The Cathlapotle archaeological site was left untouched until the early 1990’s.
Today, Cathlapotle is one of the few archaeological sites on the Lower Columbia River that has withstood the ravages of flooding, looting, and development. A decade of archaeological research — the result of a partnership between the U.S. Fish and Wildlife Service, the Chinook Tribe, and Portland State University — has produced a wealth of information about the Chinookan people who lived on the river long before Lewis and Clark first observed Cathlapotle in 1805. This replica plankhouse was built based on findings from the archaeological site as well as additional sources of information. Built by more than 100 volunteers over the course of two years, the 37′ x 78′ cedar plankhouse is constructed largely from timber donated by local landowners and national forests. Grant funding, private donations and diverse community partnerships have built a feature for the past on the Ridgefield National Wildlife Refuge. This full-scale Chinookan-style cedar plankhouse on the Refuge serves as an outdoor classroom for interpreting the rich natural and cultural heritage preserved on Ridgefield National Wildlife Refuge. See Support & Sponsors for a list of the organizations that contributed to the building of the Plankhouse and the continued support of our grant funded education programs.
