Beauty - I drove right past that area 2 years ago on vacation.

But at the time I didn't know much about geocaching or have a gpsr.
I didn't see a listing for it on GC so it may have been archived. Two nearby caches by Waterboss seem to have plenty of activity.
What struck me about the region was that it went from mountain rain-forest to semi-arid in the space of an hour or two drive (Rainier to Yakima).
