Hudson Highlands

The Hudson Highlands are mountains on both sides of the Hudson River in New York state lying primarily in Putnam County on its east bank and Orange County on its west. They continue somewhat to the south in Westchester County and Rockland County, respectively. The highlands are a subrange of the Appalachian Mountains.

North to south they fall between Newburgh Bay and Haverstraw Bay, the latter forming the northern region of the New York - New Jersey Highlands.

The Hudson River enters this region in the south at Dunderberg Mountain near Stony Point, and from the north in the vicinity of Breakneck Ridge and Storm King Mountain near Cornwall, New York. These highlands have played a significant role in America's environmental, cultural, and military history.
