It is steep as hell. Straight up the mountain, no foolin around. I hiked it a few years ago with a full pack, it nearly kilt me. But it gets you up the mountain in a hurry. Seemed pretty easy to follow.
I got in from the Elk Lake Creek trailhead.
Rob,
It's probably a good thing that you didn't try that loop, because that 14 miles is really more like 22 (if I understand your route correctly).
