The MacIntyre Mountains or MacIntyre Range is a range of mountains in the High Peaks region of the Adirondacks, due west of Mount Marcy, in northeastern New York State. The range runs 8 miles (13 km) from southwest to northeast. Its sheer southwest slope makes up one side of Indian Pass, and a northeastern spur forms the cliffs of Avalanche Pass. From southwest to northeast, the range includes Mount Marshall, Iroquois Peak, Boundary Peak, Algonquin Peak, and Wright Peak. Algonquin is the second-highest peak in the Adirondacks.
