Moggy Hollow

Driving east from Far Hills on Liberty Corner Road (before you get to I-287), the land drops off to the right into a deep gorge called Moggy Hollow.   This was once, 19,000 to 14,000 years ago, the outlet to Lake Passaic, a 30-mile-long lake, created when the Wisconsin Glacier blocked the area’s natural drainage system.  Today, Moggy Hollow Natural Area (adjacent to Leonard J. Buck Garden) in Far Hills is preserved by the Raritan Headwaters Association. 

No trails exist into the hollow itself, which is marshy and surrounded by the steep sides of the gorge. Moggy Hollow was selected for inclusion in the National Registry of Natural Landmarks in 1970.  The Great Swamp is also a local remnant of Lake Passaic.
