The Helderberg Escarpment, also known as the Helderberg Mountains, is an escarpment in eastern New York, United States, roughly 11 miles (18 km) west of the city of Albany.[2][3] The escarpment is the northeastern extremity of the Allegheny Plateau. It rises steeply from the Hudson Valley below, with an elevation difference of approximately 700 feet (from 400 to 1,100 feet) over a horizontal distance of approximately 2,000 feet. Much of the escarpment is within John Boyd Thacher State Park, and has views of the Hudson Valley and the Capital District.
