Talcott Mountain of central Connecticut, with a high point of 950 feet (290 m), is a 13-mile (21 km) long trap rock mountain ridge located 6 miles (10 km) west of the city of Hartford. The ridge, a prominent landscape feature, forms a continuous line of exposed western cliffs visible across the Farmington River valley from Farmington to Simsbury. Talcott Mountain 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.
