On the south side of the Kettle River, south of Vulcan Mountain, in Washington State, U.S. is the Tonota Creek drainage. A massive gneissic rock buttress stands vertical facing north to the river. Center of this cliff face is a 150' vertical crevasse indenting 100' into the rock but never more than 20 in width. Climbing buddy Lutje & I did side by side abseiling into this cave like crack. It was a delightful way to explore these cool vertical walls on a hot summer day. He took this shot of yours truly with my Nikon.
