I haven't had a chance to ride these yet so I don't have any commentary.
Location: Moab, UT
Directions: Head north on Main Street out of town. After crossing the river, (on your left before you reach Arches Park), turn left on Potash Road. This road takes back towards town, along the river, through the Portal, and along Wall Street rock-climbing area. The trailhead comes up just after a sign saying "Dinosaur Tracks". Take a sharp right turn (a little ways past mile marker 10). (from Trailmonkey's site)
Technical Level: High
