The Metacomet Ridge, Metacomet Ridge Mountains, or Metacomet Range of southern New England, United States, is a narrow and steep fault-block mountain ridge known for its extensive cliff faces, scenic vistas, microclimate ecosystems, and communities of plants considered rare or endangered. An important recreation resource located within 10 miles (16 km) of a population corridor of over 1.5 million people, the ridge is home to four long-distance hiking trails and over a dozen parks and recreation areas including several state and nationally recognized historic sites. Because of its natural, historic, and recreational value, the ridge has been the focus of ongoing conservation efforts involving municipal, state, and national agencies and nearly two dozen non-profit organizations.
The Metacomet Ridge extends from New Haven and Branford, Connecticut, on Long Island Sound, through the Connecticut River Valley region of Massachusetts, to northern Franklin County, 2 miles (3 km) short of the Vermont and New Hampshire borders, a distance of 100 miles (160 km). Younger and geologically distinct from the nearby Appalachian Mountains and surrounding uplands, the Metacomet Ridge is composed of volcanic basalt, also known as trap rock, and sedimentary rock in faulted and tilted layers many hundreds of feet thick. In most but not all cases, the basalt layers are dominant, prevalent, and exposed. Although only 1,200 feet (370 m) above sea level at its highest, with an average summit elevation of 725 feet (221 m), the Metacomet Ridge rises dramatically from much lower valley elevations, making it a prominent landscape feature.
Metacomet, also known as Metacom and by his adopted English name King Philip, was a Wampanoag and the second son of the sachem Massasoit. He became a chief of his people in 1662 when his brother Wamsutta (or King Alexander) died shortly after their father Massasoit. Wamsutta's widow Weetamoo (d. 1676), sunksqua of the Pocasset, was Metacomet's ally and friend for the rest of her life. Metacomet married Weetamoo's younger sister Wootonekanuske. No one knows how many children they had or what happened to them all. Wootonekanuske and one of their sons were sold to slavery in the West Indies following the defeat of the Native Americans in what became known as King Philip's War.
At the beginning Metcom sought to live in harmony with the colonists. As a sachem, he took the lead in much of his tribes' trade with the colonies. He adopted the European name of Philip, and bought his clothes in Boston, Massachusetts.
But the colonies continued to expand. To the west, the Iroquois Confederation also was fighting against neighboring tribes in the Beaver Wars, pushing them from the west and encroaching on his territory. Finally, in 1671 the colonial leaders of the Plymouth Colony forced major concessions from him. Metacomet surrendered much of his tribe's armament and ammunition, and agreed that they were subject to English law. The encroachment continued until hostilities broke out in 1675. Metacomet led the opponents of the English, with the goal of stopping Puritan expansion.
