Massachusetts is a New England state, bordered by New Hampshire, Vermont, New York, Connecticut, Rhode Island, and the Atlantic Ocean. Its landscape includes the Berkshire Hills in the west, the Connecticut River Valley, central uplands, eastern lowlands, and an indented Atlantic coastline with bays, harbors, and sandy shores. Mount Greylock, rising 3,491 feet (1,064 meters) in the Berkshires, is the state’s highest point.
Important waterways include the Connecticut River, the state’s longest river, along with the Merrimack, Charles, Housatonic, and Blackstone rivers. Quabbin Reservoir is Massachusetts’ largest inland water body by surface area and supplies drinking water to many communities. Other notable lakes and reservoirs include Wachusett Reservoir, Lake Cochituate, and Webster Lake, also known as Lake Chaubunagungamaug. Cape Cod, Buzzards Bay, Massachusetts Bay, Martha’s Vineyard, and Nantucket shape the southeastern coast. These varied landforms support forests, wetlands, wildlife habitats, recreation, and diverse local environments.
