Breakneck Ridge Hudson Highlands Topography.

Breakneck Ridge is a mountain along the Hudson River between Beacon and Cold Spring, New York, straddling the boundary between Dutchess and Putnam counties.

It has several summits, the highest, some distance inland, reaching approximately 1,260 feet (384 m) above sea level. The southern face of the peak is remarkable for its striking cliffs, the result of quarrying in past years.
