Hunterdon Plateau is a
plateau in western
Hunterdon County,
New Jersey. It borders the higher
Musconetcong Mountain to the northwest, the
Delaware River to the west,
Amwell Valley to the south and the lower lying areas of the
Newark Basin to the east. The plateau's edge follows a line from
Raven Rock to
Flemington. From there it follows a curved path west of the
South Branch Raritan River until it meets with the Musconetcongs. It is generally unmarred as a plateau, excluding some of the small valleys of tributaries along the Delaware, of Lopatcong Creek and
Wickecheoke Creek and Cakepoulin/
Capoolong Creek Valley. Other features are
Thatcher's Hill and
Sand Hill which form southeastward extensions to the plateau due to a valley of Walnut Brook and the curve of the plateau there. This also occurs between Lockatong Valley and the Delaware River. A small ridge called
Barren Ridge runs through
Alexandria and
Union Township rises slightly above the rest of the plateau. Another feature in
Holland Township called
Gravel Hill also rises above the rest of the plateau. There are numerous cliffs along the Delaware where the plateau meets it such as
Milford Bluffs where
prickly pear cacti grow, a rarity in Hunterdon County. The pleateau includes
Milford, New Jersey,
Frenchtown, New Jersey, parts of
Kingwood,
Delaware,
Raritan Township,
Flemington,
Franklin Township,
Union Township,
Bethlehem,
Alexandria and
Holland. Because of the soil types and relatively flat terrain on the plateau, there are still many farms across the area.
