Some Rock Art in the Roost

March 22, 2025

I wanted to do more long-ish desert hikes while the weather was mild so I picked a couple from my inventory of already-planned trips, which turned out to be a minor mistake that caused me to completely miss the rock art I was planning to see! But it didn’t ruin the trip or anything, I still saw a lot of great rock art, just not the specific panel I went there to see. I left home early on Saturday and arrived at the dirt road turnoff leading into Robber’s Roost before sunrise.

After quite a bit more driving I arrived at my starting spot on the side of a dirt road. I’d been nervous about road conditions because I still haven’t fixed the 4WD in my truck since it stopped working nearly a year earlier (and probably never will because it’s an electrical problem I can’t track down), but there were no significantly sandy sections so my worries were unfounded. I hiked across the flat and nondescript desert, with only the Henry Mountains for a landmark, until eventually I reached the edge of the canyon I intended to hike. I dropped below the rim, crossed a large slickrock area, and descended an old stock trail until I was down in the canyon proper.

The rest of the day was filled with the usual: miles and miles of walking the canyon floor, stopping often to investigate with binoculars, and photographing the rock art I found along the way. I was surprised to only see one inscription the entire way. There were a few alcoves but none had much of anything inside. I also saw several natural arches, including one that was quite large but which I couldn’t get a good view through due to a very steep slope covered in brush. It should have been easier-going but in a few spots I noticed trails climbing out of the canyon bottom so I followed them, assuming that they were bypassing pools or brushy spots, but on the way back up the canyon I skipped those bypass trails and didn’t see any major obstacles.

Most of the rock art I saw I’d already known the location of beforehand. But one panel in particular I missed because I had planned this trip maybe a year or two earlier. I knew that somewhere in the canyon were some very faded pictographs, and I’d looked at photos of them when planning the trip, but when I was actually in the canyon I couldn’t remember at all what the pictos looked like. When I saw some faded pictographs at one of the panels I just assumed those were the ones, even though I didn’t think they looked as faded as I was expecting. It wasn’t until returning home and reviewing the photos that I realized the very faded pictos weren’t the same as the only slightly faded ones I’d actually seen. And I was able to match up photos of those very faded pictographs with some scenery photos I’d taken in the canyon to determine the exact location, so at least if I ever return I won’t have to search them out. Here’s just a small selection of the rock art I saw, but there are many more photos in the full album.

I climbed out of the canyon using the same route I’d taken in, and back at the truck I enjoyed a snack and a drink before finding a place to camp for the night. The next day I planned to hike to Point of Rocks, just a couple of miles from where I camped.
