Bald Mountain stands in Greene County, New York, on Patterson Ridge east-southeast of Prattsville. Its significance lies in both its position and its drainage, with water flowing south to Schoharie Creek and north to Batavia Kill. As one of several modest summits in the Catskill area, it is defined less by great height than by its place along a ridge line and at a watershed divide, forming a small but distinct landmark above the surrounding valleys.
