This was kind of a long drive for such a short hike. I went down the Tidwell Draw road in the Swell to the San Rafael River, then hiked into Thompson Hole to find a geocache and some petroglyphs. Thompson Hole is an abandoned river meander where the San Rafael cuts through the Reef, and there’s an old bulldozed road leading into the bottom. There’s a new (within the past few weeks) “No Vehicles” sign just before the road descends, however, so I parked there and walked the rest of the way. I hiked about two miles and spent two hours looking for rock art in the area. Afterward I intended to hike a couple of small drainages in the San Rafael Reef north of there, but in the nearly-100-degree heat I wasn’t feeling up to it.
