Ah! I lived (and mafisto too) underneath that for a week. It's overlooking a campground almost at the entrance to Sandflats and the Slickrock trail. We headed out a few years ago and camped underneath it.

The woman that ran the place was just in awe of people that did it, she had stories of the nearly annual "some dumbass drove off the edge" event, and could cite numerous instances where people literally went right off the side. Incredible amount of deaths out there, in fact while we were there, someone drove off the side of Gemini Bridges, a local even. The bodies were pulled up, but the jeep and it's contents were still there. They didn't know how they were supposed to get it out.

Anyhow - I may have some other pictures of the place, from the side. I may have a follow up post...
