The Natural Entrance for Wind Cave (Wind Cave National Park)

At this point, the Park Ranger on the Natural Entrance Cave Tour explained that this was the only natural opening in Wind Cave. Because of that, strong winds can blow either way (inside or out) to equalize the air pressures. A full telling of this emergence story can be found here (www.nps.gov/wica/learn/historyculture/the-lakota-emergenc...).
