About this spot
This flooded limestone quarry sits along the Delaware River in Lower Mount Bethel Township, roughly seven miles north of Easton on PA Route 611, directly behind the historic (closed 1964) Alpha Portland Cement site and across the road from the public Sandt's Eddy boat launch. The pit is worked by Eastern Industries as an active aggregate quarry and is not open to the public — reaching the water means crossing posted no-trespassing signs, fences, and active rail lines. The area has seen multiple drowning deaths in recent years amid rising illegal visits, with water depths reported over 100 feet and hidden ledges. Depths, submerged equipment, and rock stability are unconfirmed and unmarked. Treat this as a dangerous, off-limits industrial site, not a legal swimming destination.
