USA - South Dakota - Badlands National Park (1)

Delicate spires are the hallmark of the predominately buff and pinkish-orange Sharps Formation located at the top of the Badlands Wall. Made up of sands, gravels, mud, and wind-deposited ash, the Sharps group is harder than other layers and erodes more sheerly. Averaging 150 feet thick, this layer is 26 to 28 million years old.

This is from Wikipedia : Badlands National Park, in southwest South Dakota, United States preserves 244,000 acres (98,740 ha) of sharply eroded buttes, pinnacles, and spires blended with the largest protected mixed grass prairie in the United States.

The Badlands Wilderness protects 64,144 acres (25,958 ha) of the park as a designated wilderness area 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 Lakota tribe and includes sites of 1890s Ghost Dances, a former United States Air Force bomb and gunnery range, and Red Shirt Table, the park's highest point at 3,340 feet (1,020 m). Authorized as Badlands National Monument on March 4, 1929, it was not established until January 25, 1939. Under the Mission 66 plan, the Ben Reifel Visitor Center was constructed for the monument in 1957-58.

It was redesignated a national park on November 10, 1978. The park also administers the nearby Minuteman Missile National Historic Site.
