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. The northern region is also known as the Hudson Highlands and the southern as the New Jersey Highlands. A broader definition would extend the region west to Reading, Pennsylvania, and east to the Housatonic
Colonial history of New Jersey existed for the 26 years between 1674 and 1702. Determination of an exact location for a border between West Jersey and East Jersey was often a matter of dispute, as was the border with New York. The border between the two sides reached the Atlantic Ocean to the north of Atlantic City. The border line was created by George Keith, and can still be seen in the county boundaries between Monmouth and Burlington/Mercer Counties; Burlington and Ocean Counties; and Hunterdon and Somerset Counties, reaching upward to a point on the Delaware River which is just north of the Delaware Water
