Cross Mountain is a peak in New York's Catskill Mountains in Ulster County, south of Phoenicia. It stands within the upper Esopus region, where tightly clustered ridges and summits shape the central Catskills landscape. Nearby mountains include Sheridan Mountain and Romer Mountain to the north and Terrace Mountain to the west. Together these surrounding heights place Cross Mountain within a dense mountainous setting characteristic of this part of the Catskills.
