Algonquin Peak, in the MacIntyre Range of the Adirondacks in northern New York, is the state’s second-highest mountain at 5,114 feet and one of the 46 Adirondack High Peaks. First recorded climbed on August 8, 1837, by a party led by Ebenezer Emmons, it took its present name in 1880 from Verplanck Colvin’s mistaken belief about a cultural boundary. Its broad, treeless summit offers sweeping views and supports 23.5 acres of alpine tundra, the largest such area in the Adirondacks. Heavy visitation has damaged this fragile habitat, leading to trail, camping, and leash regulations and stewardship efforts to protect it.
