Tamanowas Rock is owned and managed by the Jamestown S’Klallam Tribe. The area is considered sacred to the S’Klallam people and has been instrumental in defining, maintaining, and enhancing cultural practices of the S’Klallam.

The site is a traditional cultural place of the S’Klallam and other tribes in the regions. Additionally, the site contains several caves, a basalt monolith, and rock shelter. This site has been named to the National Register of Historic Places pursuant to criteria A, because the caves both offered a place of refuge for the S’Klallam people and a location of religious importance. The rock shelter demonstrates that this was an occupation site, at least seasonally. The site is located on Jamestown S’Klallam Tribal trust property within the Tribe’s Land Consolidation Area. To relocate from the intersection of Washington State Highway 20 and Anderson Lake Road, travel east on Anderson Lake Road for 2.18 miles then turn left at an unnamed two-track road and park. Walk north for .25 miles and turn left (west) onto a trail and walk approximately 300 feet and turn right. Tamanowas Rock will be approximately 200 feet at the end of the trail. The site is open to the public and a sign is in place that states that the site is a sanctuary and intended for preservation.  For more history on understanding theTamanowas Rock Sanctuary click on the link.
