Coudersport Ice Mine, Ice cave in Sweden Township, Pennsylvania.
The Coudersport Ice Mine features a 40-foot-deep shaft where thick ice formations develop during spring and summer months, reaching lengths of 25 feet.
Silver prospectors discovered this natural ice formation in 1894, leading to its development as a tourist destination that remained active until temporary closure in 1990.
The ice mine serves as an educational site where geologists and students examine the natural phenomena of seasonal temperature variations and ice formation patterns.
Visitors can access the mine from April through September, with guided tours starting at the gift shop and continuing to the viewing platform.
The cave demonstrates reverse seasonal behavior, as ice forms during warm months and melts during winter due to specific air circulation patterns through rock crevices.
