The Nez Perce, Umatilla, Warm Springs and Yakima Indian tribes signed treaties with Congress in 1855. In the year 2000 the Cowlitz Indian tribe was acknowledged as a tribe by the federal government. These treaties ceded to the United States legal title to millions of acres of land. They also reserved and guaranteed certain aboriginal rights exercised by Native American people since time immemorial. These legally protected rights belong to each Indian tribe and are regulated and enforced by the respective Native American tribal governments. The Native American tribal governments exercise inherent sovereign powers, as limited by treaty or act of congress. Skamania County must observe Native American treaty rights and recognize that these tribes have many archaeological and cultural resources within the county.
