The National Speleological Society conducted an official expedition to Wind Cave in 1959. It was led by Robert F. Brown. Although the trip was intended to be of a preliminary nature and lasted only 10 days, more surveying and scientific research was conducted during these 10 days then all other previous times.

Approximately 3 miles of cave were mapped. A good portion of this was the resurvey of tour routes, but it also included a large section of the northwest part of the cave including the surveys of places such as: the Attic, Plummer’s Pit, the Bishop Fowler’s Loop, and Brown Canyon.

During the expedition and with additional months of laboratory work, enough information was collected and analyzed to permit a complete study of the cave’s mineralogy, a reconnaissance of the cave’s fauna, and a preliminary account of the cave’s geology.

Natural Entrance of Wind Cave

Winds caused by changes in barometric pressure are what give Wind Cave its name. These winds have been measured at the cave's walk-in entrance at over 70 mph. The winds at the natural entrance of the cave attracted the attention of Native Americans and early settlers.
