The southwest corner of Massachusetts is an interesting destination because it is moderately challenging, offers great views, and is historically significant. The original boundary between Massachusetts and New York created a 1010 acre parcel lying west of the Taconic mountains but belonging to Massachusetts. This area, known as Boston Corner, was difficult to govern due to its remote location. By the early 1850's it had become a haven for outlaws who raided nearby New York counties and then took refuge across the state line. In 1853 Massachusetts ceded a triangular section of land to New York by moving the southwest corner of the state east to its current location. The cession was approved by the U. S. Congress in 1855. In addition to creating the current southwest corner, the cession also created a new westermost point in Massachusetts and a FIP (formerly important place) where the southwest corner used to be. All three locations are monumented and provide interesting goals. Towns in this area include Stockbridge, Housatonic, Great Barrington, New Boston, Sheffield and New Marlborough.
