Diepolder Cave, Florida, 1998

Photo: Diepolder Cave

"No sunlight reaches the bowels of Diepolder Cave, leaving this large chamber—250 feet [76 meters] deep—devoid of life. Florida's caves have been tough on divers too: Since 1960 some 300 have died underground."

(Text and photograph from "Unlocking the Labyrinth of North Florida Springs," March 1999, National Geographic magazine)
