There are three summits, with airy class four climbing required to get to the higher north summit. It took about 20 minutes to find my way to the north summit, sign the register, send a Spot message, and return to where I had left my boots. That was 20 minutes of really paying attention to every move I made. After stashing my rock shoes, I headed back down the route that I should have climbed in the first place. By the time I got back to camp, I had been hiking eleven hours.
And here's a picture of some of that Thunder Mountain route that Bob covered:
