A caver measures wind speed at the Humdinger / NPS file photo

Due to changes in barometric pressure, strong winds blow through Jewel Cave’s passages miles from the natural entrance. Areas in the cave where the wind is exceptionally strong or loud have names like Hurricane Corner, Whistle Stop, Exhaust Pipe, Humdinger, and Drafty Maneuver.
