Jackelope,
They are there. As I think that Huntwa and Pacyew can attest, there are a lot of goats up there. Most any place in WA (cascades and Olympics) that has subalpine areas typically will hold some goats. I've seen them on every pass and in most of the high country areas. I did some climbing in the 7devils wilderness (Idaho) last year and the three goats we passed on the way up were still there on our way down. When they are comfortable, they'll stay in one spot for quite some time. Saves energy
