The Black Hills (Pahá Sápa in Lakota, Moˀȯhta-voˀhonáaeva in Cheyenne) are a small, isolated mountain range rising from the Great Plains of North America in western South Dakota and extending into Wyoming, USA. Set off from the main body of the Rocky Mountains, the region is something of a geological anomaly—accurately described as an "island of trees in a sea of grass." The Black Hills (South Dakota) 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 Pahá Sápa. The hills were so-called because of their appearance from a distance, covered in trees.

Native Americans have a long history in the Black Hills. When gold was discovered in 1874, a gold rush swept the area prompting the US government to re-assign the local Native Americans to other reservations in western South Dakota. Unlike the rest of the Dakotas, the Black Hills were settled primarily from population centers to the west and south of the region, as miners flocked there from earlier gold boom locations in Colorado and Montana.

Today, the nearby reservations and Ellsworth Air Force Base make for a unique diversity in population different from that of the rest of Wyoming or South Dakota. As the economy of the Black Hills has shifted from natural resources (mining and timber), the hospitality and tourism industry has grown to take its place. The major tourist spots include Mount Rushmore, Custer State Park, Crazy Horse Memorial, and the Sturgis Motorcycle Rally.

History

Native Americans have inhabited the area since at least 7000 B.C. The Arikara arrived by 1500 A. D., followed by the Cheyenne, Crow, Kiowa and Pawnee. The Lakota arrived from Minnesota in the eighteenth century and drove out the other tribes, claiming the land, which they called Paha Sapa, for themselves.

After the public discovery of gold in the 1870s, the conflict over control of the region sparked the last major Indian War on the Great Plains, the Black Hills War. The 1868 Treaty of Fort Laramie had previously confirmed the Lakota (Teton Sioux) ownership of the mountain range. But with that treaty being contested, they additionally claimed rights to the land saying that in their culture it was considered the axis mundi, or sacred center of the world. Some consider this ad hoc claim of spiritual status a dubious pretension to keep the gold-rich territory since the Sioux tribe had only discovered the Black Hills about 100 years earlier (1765) and that they themselves took the land by force from its previous residents (the Cheyenne tribe) in 1776.

Although rumors of gold in the Black Hills had circulated in North America for decades (See Thoen Stone and Pierre-Jean De Smet), Brevet Major General George Armstrong Custer of the 7th US Cavalry led an expedition into the Black Hills in 1874 and discovered gold in French Creek in the Southern Black Hills. An official announcement of the presence of gold was made through newspaper reporters who accompanied the expedition. The following year, the first detailed survey of the Black Hills was conducted by the Newton-Jenney Party. The surveyor for the party, Dr. Valentine McGillycuddy, was the first white person to ascend to the top of Harney Peak, the highest point in the Black Hills, reaching 7242 feet above sea level.
