The Blackhead Mountains range is located near the northern end of the Catskill Mountains, in Greene County, New York, where it divides the towns of Windham and Jewett. The three named peaks in the range — Thomas Cole Mountain (3,940 feet; 1,201 m), Black Dome (3,980 feet; 1,213 m) and Blackhead Mountain (also in the 3,940-foot range) — are the fourth, third and fifth highest peaks in the Catskills respectively. The gap between Thomas Cole and Black Dome is, at 3,700 feet, the highest in the Catskills.
To the west of Thomas Cole are two lesser, officially unnamed summits known locally as Camel's Hump (3,520 feet; 1,073 m) and Caudal (3,320 feet; 1,012 m). All except Blackhead can be climbed via the popular Black Dome Range Trail; a short spur from that trail leads to the Escarpment Trail atop Blackhead.
