Massachusetts Terrain: From Coastal Plain to Berkshire Peaks

Massachusetts packs remarkable geographic variety into 10,565 mi²:

Major Regions

• Coastal Plain (Eastern MA): Low, flat to gently rolling; Boston Basin, Cape Cod (glacial moraine/outwash), Islands (Martha's Vineyard, Nantucket). Sea level to ~100 ft.
• Central Uplands: Rolling hills, drumlins, scattered monadnocks (Wachusett Mt 2,006 ft). Worcester Hills, Quabbin Reservoir.
• Connecticut River Valley: North-south trough, fertile alluvial soils, historic agricultural heart. Divides east/west.
• Berkshire Mountains (Western MA): Taconic & Hoosac Ranges (northern Appalachians). Mount Greylock: 3,491 ft—state high point. Rugged, forested, scenic.

Key Features

• Glacial legacy: Drumlins, kettle ponds, erratics, Cape Cod/Islands = terminal moraine.
• Rivers: Charles, Merrimack, Connecticut, Housatonic, Deerfield.
• Forests: 60%+ forested (oak-hickory, northern hardwoods, white pine).
• Coastline: 1,500+ mi (tidal) — rocky north, sandy south/Cape.

Human Impact

Boston's Back Bay, Fenway, Seaport = filled tidelands. Quabbin Reservoir (1930s) drowned 4 towns. Dense development east of I-495; rural/forested west.

From salt marsh to alpine summit, Massachusetts is a microcosm of New England geology.
