Underhill #528

Underhill is a 50-inch trail in the Hayfield Draw OHV area that goes through a rolling desert terrain in the Sonoran Desert, around 3,600 feet in elevation. This one is fun for dirt bikes because it is narrower in spots, almost like a single track. It goes west from the intersection with Camp Verde #545 and rides across the top of a flat desert mesa, on a wider two-track with some ruts and loose rocks. Then it starts to go along the rim of the small rolling hills, on a little bit shelfier of a trail, and this is where it narrows up. It continues like this for the rest of the trail, with a bit of loose rock and small hills, until it intersects with Aultman. The narrow spots would still be easy for an ATV, it just looks mostly ridden by dirt bikes.
