highest point (2,680 feet 【817 m】) in the Maritime Provinces (New Brunswick, Nova Scotia, and Prince Edward Island) of Canada, 70 miles (110 km) east of Edmundston, N.B., near Nictau and Nepisiguit lakes. Structurally it is a monadnock, or erosional remnant, rising above the 1,000-foot (305-metre) level of the surrounding highlands, which are an extension of the Appalachian region. The mountain, focus of a provincial park in Restigouche county, was named in 1899 after General Thomas Carleton, New Brunswick's first governor.
