🏞️ Monument Mountain (reservation)

Monument Mountain is the name of a popular 503-acre (204 ha) open space reservation located in Great Barrington, Massachusetts on the southeast side of Monument Mountain. The reservation is centered on the 1,642 feet (500 m) subordinate summit of Peeskawso Peak. It is managed by The Trustees of Reservations, a non-profit conservation organization and is notable for its expansive views of the Housatonic River Valley, the Berkshires, the Taconic Mountains, and the Catskill Mountains of New York from the knife-edge summit of Peeskawso Peak. Monument Mountain, composed of erosion resistant quartzite, is of The Berkshires geology. The reservation receives more than 20,000 visitors a year. The mountain was logged for charcoal to fuel a furnace in Vandusenville at the corner of Division Street and Route 41 in Great Barrington. Remnants of the furnace can be seen if one stands on the Route 41 bridge and looks upstream on the Williams River.
