Gary Soule of Sturgeon Bay always learns something new when he meets up with other cavers. A recent caver’s convention in Helena, Montana was no exception. Soule and other cavers learned of new areas for exploration beneath South Dakota and getting there is similar to climbing Mount Everest.
Soule says the discovery of the underground lakes at Jewel Cave, South Dakota shows that there are many things humans have yet to learn about the earth from the inside.
