I was tying to find a better place to shoot a small arch in Arches National Park this past April and I went off trail scrambling over rocks. Then I saw this rather flat area and headed for it. This is about a mile or two from the campground. Suddenly I was on a peninsula of rock with about 30 feet on one side and maybe 50 on the other and it was down to about 3 feet wide and just jutting out into space. That was enough for me, I sat down and took a photo and CAREFULLY retraced my steps.
