"The Kittatinny Ridge (meaning “Endless Mountain” in the Lenape Native American language) comes to an abrupt, spectacular end at Mount Tammany. The 1,527-foot ridge plunges 1,200 feet into the Delaware Water Gap. This river gorge, one of New Jersey’s most acclaimed natural treasures, has attracted painters, hikers, canoeists, and fresh-air lovers since the 1800s.
Today the great resorts are burned or gone bust, but the Gap remains, protected within the Delaware Water Gap National Recreation Area. The gorge serves as gateway to the Upper Delaware River Valley, a tapestry of folded mountains, tumbling waterfalls and forested bottom land supporting black bear, migrating golden eagles and spawning shad."
