Hudson Highlands

The Hudson Highlands are mountains on both sides of the Hudson River in the U.S. state of New York, between Newburgh Bay and Haverstraw Bay, which form 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 played a significant role in America's military, cultural and environmental history.

The bedrock of the Highlands is part of the Reading Prong and more than a billion years old, formed during the Grenville Orogeny. It represents the very core of the Appalachian range, which has been formed by successive mountain-building events (orogenies). The present mountains have been exposed by the process of isostasy through the late Cenozoic Era. The hills were given their rounded form when glaciers cut through the Appalachian Mountains here, the Highlands are among the lowest summits in that range (indeed, the Appalachian Trail reaches its lowest elevation in the Trailside Zoo between Bear Mountain State Park and Bear Mountain Bridge). Conversely, the river becomes narrower and deeper through the Highlands, reaching its deepest point of 216 feet (66 m), near Garrison. Many stretches are challenging to navigate, earning nicknames like "World's End."
