Mount St. Helens is now listed on the National Register of Historic Places, now registered as a “Traditional Cultural Property” for the Cowlitz Indians and the Confederated Tribes and Bands of the Yakama Nation. The designation covers more than 12,500 acres of land in the Mount St. Helens National Volcanic Monument. Forest Service officials say that Mount St. Helens is of particular importance to the Cowlitz, falling within the area that the tribe made with its original land claims in the 1850’s. Tribal Chairman William Iyall says that the listing honors the long relationship between the Cowlitz people and one of the principal features of their traditional landscape. More than 80,000 properties are now listed on the National Historic Register, but only 23 are listed as Traditional Cultural Properties.
