Coudersport Ice Mine. Folded Paper. Good.

Three-panel folded brochure; one side is a road map; the other has distances, a photo and promotional text, and a place to address and send to a friend. Measuring 12 by 9 inches when fully opened.

Evenly age-toned with a ½ in closed tear at the bottom right-side fold.. The Coudersport Ice Mine is an ice cave located in Sweden Township, Pennsylvania, that forms icicles in the spring and summer but not in the winter. Ice formations appear in the shaft during the spring of the year, continue through the hot weather, and disappear in winter.

Tucked away in the rolling hills of Potter County is one of the oddest natural wonders in Pennsylvania: The Coudersport Ice Mine.

The ice mine was discovered by prospectors searching for silver in the mountains outside of Coudersport. After removing the moss along a promising hillside, the men were shocked to discover a layer of ice on this hot summer day.

Continuing to dig, they opened a shaft that was roughly 10×12 feet and had a depth of 25 feet. Inside, they found not only large pieces of ice, but also human remains, a petrified fish, and fossils.

No one knows exactly what causes the ice to form in this narrow area.

The mine is located on a hillside, shielded from the sun and wind. Ice begins to form in April and continues to build up as the weather warms. Then, starting in September, the ice begins to melt, with only a residual amount remaining during the winter months.

The mine was closed to tourists in the 1980's but reopened in 2014.
