Snow late Oct to mid May. Trail closure 11/16 to 5/14
If you run down this from Crystal Creek Road you'll be in for a treat. The trail is open to motorized vehicles but doesn't get heavy traffic. It is mostly forested with a gnarly rock patch shortly after you start your descent. The forest service has put water bars in the trail.
Running up this trail is doable too.
WARNING: Corral creek contains naturally occurring arsenic, don't drink the water up there.
