Wind Cave keeps getting longer. The National Park Service now counts 167 miles of known cave passage, as of 2024.
Survey teams add new passage every year. The survey reached 100 miles in 2001, and the park celebrated the 150th mile in 2019.
The Friends of Wind Cave National Park have helped that work: we funded survey gear for the cave exploration teams, and in 2022 helped pay for equipment for a camp in the cave, so teams can stay underground longer.
