This 2.3-mile trail is very rarely used, even by Crested Butte locals! The map itself says that this trail is difficult to navigate and locate, so the best I can do is to tell you "good luck." The GPS data uploaded should be correct, but with the very minimal traffic the undergrowth grows up quickly and obscures the entrance to this trail. However, if you do find it, it's a brake-burning descent through some deliciously treacherous terrain if ridden from Cement Mountain Trail. If ridden from the bottom, this is a relentless hike-a-bike climb.
