The Berkshires ( or ), located in the western parts of
Massachusetts and
Connecticut, is both a specific highland geologic region and a broader associated cultural region. The region is also referred to as the
Berkshire Hills, Berkshire Mountains, and, with regard to its
physiography,
Berkshire Plateau. Sir Francis Bernard, the Royal Governor, named the area "Berkshire," to honor
his home county in England. Tourism is a principal industry, relying heavily on cultural art attractions and recreation.
Definition and context

Depending on the application, "The Berkshires" may have several different meanings.
Politically,
Berkshire County, Massachusetts was a governing body formed in 1761; it includes the western extremity of the state, with its western boundary bordering New York and its eastern boundary roughly paralleling the watershed divide separating the
Connecticut River watershed from the
Housatonic River-
Hoosic River watersheds. Geologically and physically, the Berkshires are the southern continuation of the
Green Mountains of
Vermont, distinct from them only by their average lower elevation and by virtue of what side of the border they fall on. As a physical geography, the Berkshires extend from the Housatonic River and Hoosic River valleys in western Massachusetts, to the Connecticut River valley in north central Massachusetts, and to the foot of the lower Westfield River valley in south central Massachusetts. In Connecticut, they extend from the upper Houstatonic River valley in the northwest part of the state, south along the western border of the state, east to the
Farmington River valley in north central Connecticut, south to the
Quinnipiac River valley in central Connecticut, then southwest to the Housatonic River valley in southwest Connecticut.
Culturally, however, the term "Berkshires" includes all of the highland region in western Massachusetts west of the
Connecticut River and lower Westfield River, and all of northwest Connecticut from the Farmington River valley in the northern part of the state in a diagonal arc west to
Winsted and
Litchfield, then southwest to
Lake Candlewood on the New York border and ending in
Ridgefield, Connecticut. The cultural region also includes the
Taconic Mountains bordering New York, which are geologically distinct from the Berkshires orogeny. Southwest Vermont and the Taconic region of New York are occasionally grouped with the Berkshires cultural region.
Counties
The Berkshires run primarily through three counties:
and
Geography
Geologically, the Berkshires are bordered on the west by the
Taconic Mountains, the
marble valleys of the
Hoosic River and
Housatonic River and, further south, by the
Hudson Highlands; to the east, they are bordered by the
Metacomet Ridge geology. They are on the average lower and less prominent than the Green Mountains of Vermont, and form a broad,
dissected plateau punctuated by hills and peaks and cut by river valleys. The Berkshires topography gradually diminishes in profile and elevation from west to east and from north to south, except where rivers have cut deep gorges and sharp bluff faces into the Berkshire plateau.
The highest point in the Berkshires geology is
Crum Hill, of
Monroe, Massachusetts; however,
Mount Greylock of the Taconic Mountains, 3,491 ft (1,064 m), the highest point in the state of Massachusetts, is considered the high point of the Berkshires cultural region. The average regional elevation of the Berkshires ranges from about 700 to 1,200 feet (213 to 365 meters). The Berkshires and related Green Mountains were formed over half a billion years ago when
Africa collided with
North America, pushing up the
Appalachian Mountains and forming the
bedrock of the Berkshires. Erosion over hundreds of millions of years wore these mountains down to the hills that we see today.
The Housatonic River, Hoosic River,
Westfield River, and
Deerfield River watersheds drain the Berkshires region in Massachusetts; in Connecticut the main river drainages are the
Farmington River, the
Naugatuck River, the
Shepaug River, and the
Housatonic River.
The largest municipalities associated with the Berkshires cultural region include
Pittsfield,
North Adams,
Adams,
Great Barrington, and
Williamstown, Massachusetts; and
Winsted, Connecticut.
History
During the
American Revolution a
Continental Army force under
Henry Knox brought captured cannons from
Fort Ticonderoga by ox-drawn sleds south along the west bank of the
Hudson River from the fort to
Albany where he then crossed the Hudson, continued east through the Berkshires and finally to
Boston. This was accomplished in the dead of winter, 1775-1776.
Ecology
As a framework for assessing environmental resources, the
United States Environmental Protection Agency in Massachusetts (Griffith et al. 1994) has defined six different types of "ecoregions" within this area: Taconic Mountains, Western New England Marble Valleys, Lower Berkshire Hills,
Berkshire Highlands, Vermont Piedmont, and Berkshire Transition. Each region is distinct from the others providing a unique habitat assemblage. Much of the Hoosic and Housatonic River Valleys have underlying bedrock limestone and marble which contribute to calcareous wetlands, unique to Massachusetts. The alkaline
pH waters support a diversity of plants and animals intolerant of more acidic waters, some which are state-listed rare or endangered. Combined with the rich
mesic forests ranging from the
northern hardwood to the
taiga or sub-alpine, makes for a valuable, biologically diverse ecosystem.
The classic study of the vegetation of the
Berkshire Highlands was Egler's 1940 monograph, covering the flora of an area stretching roughly from Pittsfield, MA in the west to Hatfield, MA in the east, and from Goshen, CT in the south, north to the
Vermont border.
Today, efforts are being made on behalf of many organizations to preserve and manage this region for biological diversity and sustainable human development. Recreation directly related to this ecology is a popular area for trout fishing, and the area's relative pristineness contributes to the popularity of nature walks in the region.

The Berkshires in winter
The Berkshires are a popular tourist attraction and vacation getaway, serving the same function in relation to
Connecticut and
Massachusetts that the
Catskills do in
New York and
the Poconos for
Pennsylvania. With numerous trails, including part of the
Appalachian Trail, large tracts of wilderness, parks like Kent Falls,
Berkshire Botanical Garden and
Hebert Arboretum the Berkshires are very popular with nature lovers. The range includes
Bash Bish Falls, the tallest waterfall in Massachusetts. The Berkshires are also home to dozens of summer camps, some of which date back to the turn of the 20th Century
Northwestern Connecticut features the covered bridges of Kent and West Cornwall, fly fishing, canoeing and spectacular fall foliage along the Housatonic River valley and the quiet woods and hills of the Appalachian trail.
The Berkshire region is noted as a center for the visual and performing arts; its art museums include the
Norman Rockwell Museum, the
Clark Art Institute, the
Massachusetts Museum of Contemporary Art (MassMoCA), and the
Williams College Museum of Art (WCMA). At
Williams College, the Chapin Library displays a wide selection of rare books and documents. Performing-arts institutions in the Berkshires include
Tanglewood Music Center in
Lenox, the summer home of the
Boston Symphony Orchestra;
Shakespeare & Company in
Lenox; summer stock theatre festivals such as the in
Williamstown and the in
Stockbridge; and America's first and longest-running dance festival,
Jacob's Pillow.
