Best I can figure, they call the upper reaches of this mountain home. It is the perfect environment for them. A nice balance of meadows and spruce cover. Great lookout points and escape routes. What it looks like on a topo doesn't give a good account of the challenges the avalanche chutes present for lateral movement. The climb is just part of the issue. Climbing with a full complement of hunting gear is another issue. Climbing quietly enough in loose rocky conditions to get within shooting range is yet another challenge. Then, if you kill one, the real challenge begins. Going back to the OP, making another 2000 feet in elevation isn't always as simple as an hour or two.
