Native American rock art is abundant in the San Rafael Swell; large pictograph and petroglyph panels are the most popular destinations. The smaller sites are often overlooked and driven past. Serpent Cross falls into the latter category. This short, grassy two-track leads to an interesting piece of rock art, a long snake with a cross for a head. It's roughly six feet long, pecked into the sandstone cliff. The site is across the deep sandy trench at the end of the track. On a short spur trail, wonderful secluded camping is in the trees along the cliff. The trail mixes hard dirt and soft sand that may require 4x4 on hot days.
