The northern boundary of the state with Massachusetts is marked by the distinctive Southwick Jog/Granby Notch, an approximately 2.5 mile (4.0 km) square detour into Connecticut slightly west of the center of the border. Somewhat surprisingly, the origin of this anomaly is uncertain, with stories ranging from surveyors who were drunk, attempting to avoid hostile Native Americans, or taking a shortcut up the Connecticut River; Massachusetts residents attempting to avoid Massachusetts' high taxes for the low taxes of Connecticut; Massachusetts' interest in the resources represented by the Congamond Lakes which lie on the border of the jog; and the need to compensate Massachusetts for an amount of land given to Connecticut due to inaccurate survey work. Perhaps the only suggested reason which can be safely ruled out is that the jog is necessary to prevent Massachusetts from sliding out into the Atlantic Ocean! In any event, the dispute over the border retarded the development of the region, since neither state would invest in even such basic amenities as schools for the area until the dispute had been settled.
