Nature
Boonton Gorge is a short, steep stretch of the Rockaway River in Boonton, New Jersey, where the river begins dropping through a fault-shaped landscape toward the Jersey City Reservoir. Formed within geologic structures linked to the late Triassic rifting that accompanied North America’s separation from Africa, the gorge packs waterfalls, rapids, pools, and boulder channels into just over a mile. It also preserves traces of the 19th-century local iron industry and includes landmarks such as Indian Rock near the old stone arch bridge. Long used for fishing, swimming, and whitewater boating, the gorge is also hazardous, with unstable trails, swift water, and fatal accidents underscoring its power.
