The trail is pure hard-pack singletrack, with about 750' overall elevation, although climbs are never greater than about .5mi and 200' elevation. Go through the gates near the parking lot, take the intro section and turn left at the arrow (next set of gates), follow left through the track and you'll have a great time.
The track is very fast, well-maintained and has a lot of great sections, including a rollercoaster section that allows you to get great speed and some air if you take them hard, and also some sweet jumps later on in the course. we had to backtrack about 4 times just to rehit a lot of the sweet sections. There is nothing exceptionally technical, just really fast and fun. The landscape is generally colorado desert, with some nice track along the rims of the cliffs and through some waist high juniper trees. This is a great track, and more than work the drive from Durango. After riding three trails there, this was a fantastic. All the locals we talked to recommended it, and I recommend getting a trail map from the local shop. There are many more trails in the Cortez area to be explored.
Right off of 160W between a shooting range and the Fairgrounds (the drive in is a little hidden, but next door to the shooting range, and practically across the street from the Fairgrounds). This is about 45 minutes from Durango.
