One of the world's longest and most complex caves and 28,295 acres of mixed-grass prairie, ponderosa pine forest, and associated wildlife are the main features of the park. The cave is well known for its outstanding display of boxwork, an unusual cave formation composed of thin calcite fins resembling honeycombs. The park's mixed grass prairie is one of the few remaining and is home to native wildlife such as bison, elk, pronghorn, mule deer, coyotes, and prairie dogs. Near Hot Springs, South Dakota.

Located in southwestern South Dakota, Badlands National Park consists of 244,000 acres of sharply eroded buttes, pinnacles and spires blended with the largest, protected mixed grass prairie in the United States. The Badlands Wilderness Area covers 64,000 acres and is the site of the reintroduction of the black-footed ferret, the most endangered land mammal in North America. The Stronghold Unit is co-managed with the Oglala Sioux Tribe and includes sites of 1890s Ghost Dances. Established as Badlands National Monument in 1939, the area was redesignated "National Park" in 1978. Over 11,000 years of human history pale to the ages old paleontological resources. Badlands National Park contains the world's richest Oligocene epoch fossil beds, dating 23 to 35 million years old. Scientists can study the evolution of mammal species such as the horse, sheep, rhinoceros and pig in the Badlands formations.

Missouri National Recreational River offers natural beauty: the forested buff-colored chalkstone bluffs to gently rolling range bottomland; the brilliant white of migrating pelicans to the rich blues of prairie asters; the soaring majesty of resident bald eagles to fleeting glimpses of the wily red fox. It offers an exciting past for your enjoyment and enrichment, from Plains Indian tribes to Lewis and Clark to steamboat captains such as Grant Marsh. Here, you can experience the dynamic character of the river's ever-changing nature, with its islands, shifting sandbars, sloughs, and treacherous, deadly snags. Both the upper 39-mile reach and the lower 59-mile reach along the Nebraska-South Dakota border combine to form one of few sections of this once vast ecosystem along the "Big Muddy" that remains in a relatively natural state.
