Ramapo Mountains


The Ramapo Mountains are a forested chain of the Appalachian Mountains in northeastern New Jersey and southeastern New York, in the United States. They range in height from in New Jersey, and in New York.
Several parks and forest preserves encompass parts of the Ramapos, and many hiking trails are in the Ramapos, including sections of the Appalachian Trail, which is maintained and updated in the Ramapo Mountains by the New York–New Jersey Trail Conference.
In New York, the mountains serve to divide Orange and Rockland Counties. The difficulty of crossing the mountains is what caused Rockland County to break away from Orange County in 1798.
The mountains are named after the Ramapo Fault, which trends northeast to southwest, and separates the eastern Piedmont geologic province from the Highland province.
The Ramapos are composed of granite, gneiss, and marble, as old as 1.3 billion years.
