Dave -
Saw a Wolvorine in the Sauk drainagge in the late 1990s and saw a wolvorine road kill from Whatcom County (near Acme) the year before. There is one seen every once in a while in the North Cascade as well as either Grizzly or their tracks (have seen their tracks but not the bear). I think the wildlife in the wilder portions of the Skagit/Sauk are as much as an attraction for me as the fish.
