There's been considerable mis-information about this rap, so here's some pictures. Pothole near the lip of the rappel. Ideal geometry for building a deadman. Force on anchor will be directly up, then a good edge to run the webbing over, which dramatically reduces the forces on the anchor. There are a few ledges below the lip, so rappellers can downclimb a ways before getting on rappel.

Two bolts placed for this rappel. The bolts themselves were placed quite well. The left one was a 3/8" Powersbolt, well set. The right was a 15mm stud-type bolt, with a high-quality steel (or stainless steel) stud. They are placed quite a ways from the edge of the drop, up this low-angle slope (a comfortable ledge to sit or stand on, but not entirely flat). Bolts are often placed in a location where they allow the use of minimal webbing (if any at all) while still providing an excellent line of pull, and an easy transition to on-rappel. When placed in this way, they (often) minimize the rope-grooving created by pulling the rope across the edge. These bolts were not placed in this way, but were placed well out of the watercourse. Bolts were removed, and holes patched. My apologies, no pictures of the patched holes (it was late, we were in a hurry).

There is a "blocking pothole" upcanyon maybe 30 feet. The blocking drop is short (10'?) and could be up-climbed with a partner-boost. Before rapping in (from a nice, clean, precise deadman anchor), we farmed rocks from up-canyon. There is available a wide selection of igneous rocks of many sizes. I asked Dave to find a 'larger rock' to use as a base rock, and he came up with this one which weighed about 100 lbs. Davey nicely 'gift-wrapped' it, then worked it into the sand, a bit, and stacked a few rocks on top.

Final rap in Mind Bender. Davey on rappel. Length = 150 feet. Kinda not-too-green this time of year.

Then we hoofed it out, got to the "moki" exit right at dark. Dave was impressed by my lead of the steps in the dark, and finding my way to the top of the mesa, in the full dark. Thanks Davy, for being my accomplice on this mission.
