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.
