The West Virginia. Cyclopedia
Like the cresting peaks of a giant wave, the sandstone cliffs atop Peters Mountain lean forward, threatening to break across the Greenbrier Valley. Upon this summit at 4,000 feet sits Hanging Rock lookout, a firetower that has been converted into a watch for migratory birds.
Hanging Rock is composed of the super-resistant Tuscarora Sandstone which forms Seneca Rocks to the northeast in West Virginia's eastern panhandle.
A three-mile access trail follows the summit ridge east from a high gap on Route 15, off W.Va.3 south of Gap Mills, West Virginia. The hanging Rock trail is part of the Allegheny Trail System, which intersects the Appalachian Trail 16-miles farther east.
