Wanapum

[3] Captain Clark’s journals provide descriptions of their dwellings, clothing, and physical characteristics.

Whether due to this religion or for other reasons, the tribe never fought white settlers, did not sign a treaty with them, and as a result retained no federally recognized land rights.

In 1942 Franklin Matthias allowed about 30 Wanapum to remain in their winter camp, with access to their customary fishing ground in the middle of the federal reservation for the Hanford Engineer Works (part of the Manhattan Project), and provided daily trucks to transport them from their winter camp on the Columbia River.

About 60 Wanapum petroglyphs were blasted from the rock before being flooded; they may be viewed at Ginkgo Petrified Forest State Park.

The indigenist Washat Dreamers Religion that founded by Wanapum Smohalla in 1850 is still practiced by some members of other tribes.
