The first photo posted is Bill Frielingsdorf descending Horsethief Bench (high SPF rating). In the blog yesterday I linked a video of this section. Few people try to descend this section due to a very high SPF (sphincter pucker factor) rating. Notice the guy to Bill's left, watching. Also notice the loose, loose conditions and random boulders littering the trail.
The second shot is Dennis Andersen popping up a climb on the Horsethief loop.
The third shot is Scott Ellis railing one of the fast sections of Horsethief.

It was a great trip. Though Moab gets good ratings for mountain bike riding, if you get a chance to check out Fruita don't pass it up.
