    Berm, Drop, Rock Face

This short trail is full of freeride goodness if you look past the beaten path. There are a couple small drops and a couple optional rock face descents. Horses and cattle some times use this trail so beware of blind corners and loose rocks. This trail is by no means a double black however you can find some big faces to roll.

      Nice combination of the Chutes and Gem DH. Return via Middle Gate.

      Great rock rolls here and there and a nice way back into The Chutes. Corners are pretty chunky and pitted. Trail day please...? This would easily get back into shape with almost any amount of attention.

      This trail is awesome as long as you don’t follow the marked trail. The marked trail here is pretty meh but keep your eyes peeled and there is a spicier way down.

      Absolutely a CCW trail. A couple really sweet rollers.
