An "Off the Beaten Path" 2.3-mile loop hike to a butte with a solar marker petroglyph, which appears sliced in half (half light / half shade) during the summer solstice sunrise. In addition to the solar marker, there are many other petroglyphs, most of them geometric patterns, but plenty of birds and four-legged animals as well. The trailhead is located at a dirt pullout just before the Dry Wash Bridge near milepost 22.
