UT: Black Dragon Canyon
Moderate trail. This is a popular wash trail just outside Green River. The track changes with each major storm so be prepared for changing conditions. You may have to pick your line through a few rock obstacles, but it is a straightforward, enjoyable trail. Don't enter if it is raining or if rain is in the forecast. This trail can be run in either direction, but west to east, or downhill, is the easiest way. The primary point of interest is an historic pictograph panel a mile or so from the east end of the canyon.
