The Taconic Mountains are a 150-mile-long sub-range of the Appalachian Mountains lying on the eastern border of New York State and adjacent New England. The range, which played a role in the history of geological science, is separated from the Berkshires and Green Mountains to the east by a series of valleys, principally those of the Housatonic River, Battenkill River and Otter Creek. The Taconics' highest point is Mount Equinox in Vermont at 3,840 feet (1,170Â m); among many other summits are Dorset Mountain, Mount Greylock and Mount Everett.

Mount Greylock with its glacial cirque, the Hopper, is geologically part of the Taconic Mountain Range although culturally associated with the Berkshires
The Berkshires are highlands located in western Massachusetts and northwestern Connecticut in the United States. Generally, "Berkshires" may refer to the range of hills in Massachusetts that lie between the Housatonic and Connecticut Rivers. Highlands of northwest Connecticut may be seen as part of the Berkshires and sometimes called the Northwest Hills or Litchfield Hills. The segment of the Taconic Mountains in Massachusetts is often considered a part of the Berkshires, although they are geologically separate and are a comparatively narrow range along New York's eastern border.
