The first part of the Crater Ice Cave trail is fairly primitive. It is more of a social trail or game trail than an actual maintained trail. This portion of the trail will travel for approximately 40 or 50 feet through a gully before climbing up into the forest. The trail makes a parallel path with the gulley for a short distance before heading into the forest.
