New York–New Jersey Highlands New York–New Jersey Highlands The New York – New Jersey Highlands is a geological formation composed primarily of Precambrian igneous and metamorphic rock running from the Delaware River near Musconetcong Mountain, northeast through the Skylands Region of New Jersey along the Bearfort Ridge and the Ramapo Mountains, Sterling Forest, Harriman and Bear Mountain State Parks in New York, to the Hudson River at Storm King Mountain.
