Expect an amazing climb or descent in a narrow arroyo that follows steeply up the mountainside. Due to the chunkiness of the arroyo rocks, this one is rated a little more difficult. But there is no exposure, except for a brief section near the top with a bit of cross-slope. You are down in the arroyo most of the way.
