Mount Loretto Unique Area is a 194-acre open space reserve and nature preserve. Mount Loretto has approximately one mile of shoreline fronting Prince's Bay and Raritan Bay. Along the shoreline are the highest ocean facing bluffs in New York State, the highest point, reaching a height of 75 feet (23 m). The bluffs are part of the terminal moraine, deposits of clay and gravel during periods of glaciation, the last being the Wisconsin Glacier which reached its southernmost terminus in Staten Island.
