It's a short drive to GSENM (Grand Staircase-Escalante Natl Monument). Once you find the right guardrail on the right curve, just open the gate and drive through, the trail goes right up the Catstair Canyon wash. (Don't forget to close the gate.)
When you actually get to the canyon, there are lots of petroglyphs and pictographs up on one section of the wall.
Some pop out; some are really hard to see. Some have been obscured, and some are just plain grafitti.
There were some flowers I hadn't seen before alongside the trail, so of course I took pictures. Don't have a clue what it is, but I like it!
It was a mighty short hike.
