Blackhead Mountains Blackhead Mountains The Blackhead Mountains range is located near the northern end of the Catskill Mountains, in Greene County, New York, United States, 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.
