Jamestown S’Klallam tribe acquires Tamanowas Rock

Thanks to alert reader Wendy B. who informs us that the Jamestown S’Klallam Tribe has obtained Tamonowas Rock, near Chimacum. The prominent rock south of Port Townsend last appeared in the pages of this website in November, 2010. According to the tribe, the public will retain access to the reserve, but absolutely no rock climbing will be tolerated on the rock, which is  a sacred place in tribal histories. A trail goes to the top.

Geologically, the rock is  adakitic dacite, a type of rock generated when the  descending oceanic plate melts. Rocks of this type are uncommon in the area. Read the full report in the Olympic Peninsula News. There is some accurate discussion about the geology, and also the role the 150-foot-tall rock has played in history. According to one story, the rock served as a refuge ‘from a flood’. The only logical flood that could impact this area is a tsunami. The most recent geologic evidence for a tsunami in the vicinity is 3000 years old.

I have updated the Tamanowas Rock page to include directions for getting there.

  1. Hi Dave, Happy New Year! Wouldn’t the 1700 Cascadia Tsunami have impacted this area?? Also I have not been able to talk to the woman who had mentioned the warming shack but will stay on it. Take care, Roger
