The Berkshire Hills are in Berkshire County at the western end of Massachusetts. They are actually three separate mountain ranges, separated by the valleys of the Housatonic River in the south and the Hoosic River in the north. East of the valleys a hilly plateau rising as high as 2,600' extends eastward toward the Connecticut River. Beyond the limits of Berkshire County it is known as the Hilltowns and is covered in the Pioneer Valley region. West of the valleys the narrower Taconic Range rises along the New York state border. The third Berkshire range is Mount Greylock (3,487', Massachusetts' high point) and its satellite peaks rising out of the valley between two upper branches of the Hoosac River.
Although the Berkshires were historically part of New England's traditions of intellectualism, idealism, subsistence farming, logging, and early industrialization, they are almost equidistant between New York and Boston. Because New York has grown considerably larger and wealthier, the Berkshires are increasingly drawn into its economic and cultural orbit.
