Trimountain

Trimountain or Tri-mountain, est. 760 feet , is a traprock mountain located 6 miles southeast of Meriden, Connecticut. It is part of the narrow, linear Metacomet Ridge that extends from Long Island Sound near New Haven, Connecticut, north through the Connecticut River Valley of Massachusetts to the Vermont border. Trimountain is known for its scenic cliff faces, unique microclimate ecosystems, and rare plant communities. The mountain is traversed by the 51-mile Mattabesett Trail.
Trimountain is located in Durham and Wallingford, Connecticut. It takes its name from its overall triangular shape, its three southern pinnacles, and the three notches between the pinnacles. A prominent landscape feature that rises 500 feet above the surrounding valleys, Trimountain is roughly 1.5 miles long by 1 mile wide, although the steepness of the terrain makes the actual square mileage much larger. Although Trimountain has been subject to intensive quarrying, which has obliterated much of the northwestern face of the mountain, the Mattabesett Trail still traverses the southern pinnacles and the wooded eastern side of the mountain.
