Buckskin Gulch
 

Buckskin Gulch in Southern Utah is the longest slot canyon in the Southwest (or more properly, the longest non-technical slot canyon, meaning you don't need ropes and such to trek through it). The sandstone canyon meanders about 12 miles before reaching the Paria River.

The petroglyphs in Buckskin Gulch are not in my book because I didn't discover them until recently (2011-12). Anyway, as far as petroglyph sites go, I'm not sure the ancient artwork is spectacular enough to be a destination. But if you happen to venture into the canyon just to hike or do photography, the glyphs add a nice bonus to your experience.

Because of Buckskin Gulch's location in the Anasazi region, I'm assuming the Ancestral Pueblo people made the rock art, probably 700 or 800 years ago. However, I haven't researched the place so I cannot say for sure. I'm also pretty sure the four-legged animals are bighorn sheep since they appear to have horns, not antlers.
