Perch Lake Mountain is a summit in New York’s Catskill Mountains, located south of Andes, with Hemlock Knoll nearby to the north and Hunt Hill to the south-southwest. It is part of the broader Catskills, a dissected plateau in southeastern New York. The region’s rugged landscape was shaped by erosion, not by the formation of a single continuous mountain chain, making Perch Lake Mountain one of many summits that reflect the Catskills’ distinctive geologic character.
