Wind Cave is the most widely known of the many limestone caverns found
near the margin of the Black Hills. Discovered in 1881, it was created a
national park in 1903. The strong currents of wind that blow alternately
in and out of the mouth of the cave suggested its name.
Boundaries of the park were extended twice and now embrace a total of
28,000 acres of federally-owned land, supporting a large buffalo herd in
its natural habitat and other wildlife, such as elk, antelope, and deer.
Chief feature of the park is the exceptional limestone cavern, noted for
its unique boxwork rarely found in other sections of the world. Other
crystalline formations in various color shadings line a series of
subterranean passages, known to be at least 10 miles in extent.
