The Wheeler Ridge Trail is located north of Bishop CA. It is quite scenic but has a short section called the Wheeler Ridge Mine Trail which is moderately challenging. Rated at a 2+. Beyond the challenging section, near the end of the trail is a very dangerous section which should be closed by the Forest Service. This section is on a narrow shelf road which is off camber and has deep, loose sand and about a 1,000 ft dropoff. A couple of years ago Bruce and I did a dramatic recovery of a Toyota pickup from this section.
