Boxwork is a type of speleothem (cave formation) made of thin blades of calcite that project from cave walls and ceilings, forming a honeycomb pattern. The fins intersect one another at various angles, forming "boxes" on all cave surfaces. Boxwork is largely confined to dolomite layers in the middle and lower levels of Wind Cave. As a matter of fact, ninety-five percent of the world's boxwork is found in Wind Cave.

According to the National Park Sevice, "In North America, both 'bison' and 'buffalo' refer to the American bison (Bison bison). Generally, 'buffalo' is used informally; 'bison' is preferred for more formal or scientific purposes. Historians believe that the term 'buffalo' grew from the French word for beef, 'boeuf.' Some people insist that the term 'buffalo' is incorrect because the 'true' buffalo exist on other continents and are only distant relatives."
