The ridge is located in the tri-state corner of New York, Massachusetts, and Vermont in the towns of Petersburgh, Williamstown, and Pownal. The ridge has several distinct knobs; those with names are, from south to north: White Rocks, 2,365 feet (721 m); Smith Hill, 2,330 feet (710 m); White Rock, the high point 2,550 feet (780 m); and Bald Mountain 2,485 feet (757 m). The Snow Hole, located along the ridgeline between Bald Mountain and the White Rock, is a crevasse in which snow can be found well into the summer.
