Description
#201510013053BW - Spring Creek meanders through the Central Black Hills of South Dakota before reaching the prairie to the east. The creek joins the Cheyenne River farther east in Badlands National Park. The Black Hills (Paha Sapa in Lakota, Moʼȯhta-voʼhonaaeva in Cheyenne, awaxaawi shiibisha in Hidatsa) are a small, isolated mountain range rising from the Great Plains of North America in western South Dakota and extending into Wyoming, USA. The Black Hills encompass the Black Hills National Forest and are home to the tallest peaks of continental North America east of the Rockies. The name "Black Hills" is a translation of the Lakota Paha Sapa. The hills were so-called because of their dark appearance from a distance, as they were covered in trees. The geology of the Black Hills is complex. A Tertiary mountain-building episode is responsible for the uplift and current topography of the Black Hills region. This uplift was marked by volcanic activity in the northern Black Hills. The southern Black Hills are characterized by Precambrian granite, pegmatite, and metamorphic rocks that comprise the core of the entire Black Hills uplift. This core is rimmed by Paleozoic, Mesozoic, and Cenozoic sedimentary rocks. The stratigraphy of the Black Hills is laid out like a target, as it is an oval dome, with rings of different rock types dipping away from the center.
