Badlands - A badland is any area where water erosion has worn away soft rock and left narrow canyons and drainage creeks that are dry most of the year. The Badlands of South Dakota are unique and beautiful because the minerals in the soil have left different-colored stripes.

Black Hills - Eroded domes that were named "Hills of Black" by the Lakota Sioux. From a distance, they appear black because they are covered with dark pines. Harney Peak, at 7242 feet, is the highest spot in South Dakota, and the highest peak in the United States east of the Rocky Mountains. The Black Hills, formed when molten rock from the earth's interior forced its way upward through a limestone layer, are known for their granite peaks and deep canyons. When the limestone cracked, water ran through the cracks and the rock was gradually worn away, creating the vast cave mazes in the hills.

Wind Cave - Wind Cave National Park, in the Black Hills, is the most famous of the caves, known for its delicate formations such as popcorn, boxwork, and frostwork. Boxwork, a paper-thin formation that resembles honeycomb, is found in only one other cave in the world. Frostwork looks like a small bush covered with frost, and popcorn looks like popcorn that you eat.
