Located outside of Wimberely Tx. Last time they checked it was 120 ft deep. Until the modern era, the Trinity Aquifer-fed natural artesian spring gushed water from the mouth of the cave But for the first time in modern history it stopped flowing in 2000 and 2008! If your gonna try to scuba dive in the well you should know eight divers have died trying to explore different underwater caves from 1964-1984. So you gotta know your stuff and have the right equiptment to do it safely...
