One of a few rock monoliths along the Thunder Mountain Trail. The most notable of these are called, "The Sentinels." I have no information whether anyone has ever climbed these formations. Some of them appear to be about low class 5. My experience is that the rock can be dangerously crumbly, and protection ops would be poor. With such potentially poor rock, a rappel from the summit might not be done very safely! August 11, 2004
