We have photographed this Running Crab Spider, Thanatus sp., on Blue Mountain and at Obstruction Point in the Olympic Mountains. There are no state records of this genus in the Olympics, according to Rod Crawford, an arachnologist at the Burke Museum, University of Washington. The genus name is wonderful, evoking the almost-scary environment: dry, rocky, steep; frozen for nine months of the year and desert-like for the other three.
