Monument Mountain is a 2.5-mile (4.0 km) long quartzite ridgeline located in Great Barrington and Stockbridge, Massachusetts in the Berkshires geology. Beside the high point, 1,739 feet (530 m), the mountain has several other distinct peaks, most notably the open, knife-edge Squaw Peak, 1,642 feet (500 m) located on the southeast side of the mountain within the 503-acre (204 ha) Monument Mountain reservation managed by The Trustees of Reservations. The mountain receives over 20,000 visitors per year.
Devil's Pulpit, part of Squaw Peak, is a free-standing pillar of stone. Flag Rock, located on the southwest side of the mountain, is an open ledge overlooking the village of Housatonic. The only official trails on the mountain ascend Squaw Peak from a parking lot on Massachusetts Route 7 north of Great Barrington center. An unnamed waterfall is located to the northeast of Squaw Peak along the Hickey Trail.
Views from Squaw Peak include the Housatonic River Valley, The Berkshires, the Taconic Mountains, and the Catskill Mountains of New York.
The west side of Monument Mountain drains into the Housatonic River thence into Long Island Sound. The east side of Monument Mountain drains into Konkapot Brook thence into the Housatonic River.
