The Petroglyph Canyon Trail, also known as Mouse’s Tank Trail, is a 0.4 mile, very easy, out-and-back trail located in Nevada’s Valley of Fire State Park. The trail ends at a chasm called Mouse’s Tank, which holds a small amount of collected rain water. Along the trail to Mouse’s Tank, you walk through a canyon that has many areas of black scorched rock with petroglyphs. They weren’t noticeable at first, but as you continue through the canyon the petroglyphs become more visible and noticeable, and really are a sight to see. There is no known interpretation of these petroglyphs, however there are some commonly accepted interpretations of what the petroglyphs could mean on a sign at the beginning of the trail.
