Pohatcong Mountain

The ridge continues on north past Washington as Upper Pohatcong Mountain. It is located in eastern Warren County, and extends northeast of Washington approximately 6 mi (10 km) to the vicinity of Hackettstown. The ridge has an average height of approximately 800 ft (240 m) and reaches a maximum summit of 1235 ft (374 m).

The term "Pohatcong Mountain" is sometimes taken to include both Pohatcong and Upper Pohatcong Mountain. The ridge is approximately 800 ft (244 m) high along much of its length. The mountain divides the watersheds of Pohatcong Creek on its northwestern flank and the Musconetcong River on its southeastern flank.
