Due to the extreme danger posed by the underwater caves beneath Jacob’s Well, the Jacob’s Well Exploration Project is the only group currently allowed to explore the system. The group began surveying the cave in the early 2000s, and has since mapped all accessible areas - a total of 6,000 feet of passageways!
