Badlands are a type of dry terrain where softer sedimentary rocks and clay-rich soils have been extensively eroded. [1] They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density. [2] Ravines, gullies, buttes, hoodoos and other such geologic forms are common in badlands.
Badlands National Park. The geology of South Dakota began to form more than 2.5 billion years ago in the Archean eon of the Precambrian.Igneous crystalline basement rock continued to emplace through the Proterozoic, interspersed with sediments and volcanic materials.
Badlands National Park (Lakota: Makȟóšiča [3]) is a national park of the United States in southwestern South Dakota. The park protects 242,756 acres (379.3 sq mi; 982.4 km 2 ) [ 1 ] of sharply eroded buttes and pinnacles , along with the largest undisturbed mixed grass prairie in the United States.

Badlands National Park was created in 1978. [58] The park features a highly eroded, brightly colored landscape surrounded by semi-arid grasslands. [59] Wind Cave National Park, established in 1903 in the Black Hills, contains an extensive cave network as well as a large herd of bison. [60]
The Bisti/De-Na-Zin Wilderness is the largest area of badlands in the San Juan Basin that is easily accessible to the public. [7] The badlands expose the longest, most complete, and most richly fossiliferous sequence of beds spanning the Cretaceous-Paleogene boundary in any single sedimentary basin in the world. [8]
The Chinle Formation is an Upper Triassic continental geological formation of fluvial, lacustrine, and palustrine to eolian deposits spread across the U.S. states of Nevada, Utah, northern Arizona, western New Mexico, and western Colorado.
The southwestern part of North Dakota is covered by the Great Plains, accentuated by the Badlands. There is also much in the way of geology and hydrology . North Dakota is about 340 miles (545 km) east to west and 211 miles (340 km) north to south, with a total area of 70,704 square miles (183,123 km²), making it the 19th largest of the 50 U.S ...
