Why Are Water-filled Pits Dangerous?
Water-filled pits can contain badly polluted water and can be very difficult to escape.
Most deaths in abandoned mines in Pennsylvania happen in quarries. Water-filled quarries look like a fun and refreshing place to swim and explore, but there are many hidden dangers. Water temperatures drop dramatically just beneath the surface, causing swimmers to get severe muscle cramps or inhale water and drown. Sheer cliffs are often unstable and can disintegrate, causing climbers to fall. Abandoned equipment, trash, automobiles and buildings lurk just beneath the surface.
Steep cliffs and remote locations make it very difficult for rescuers to enter the site and save lives. And remember, there are no lifeguards in abandoned quarries. Click this link to see pictures of water-filled pits.
