History

In 1874, US Army commander George A. Custer led a group into the Black Hills area. He and some of his officers climbed the crest now called

Black Elk Peak Black Elk Peak is the highest natural point in the U.S. state of South Dakota and the Midwestern United States. It lies in the Black Elk Wilderness area, in southern Pennington County, in the Black Hills National Forest. The peak lies west-sout ...

, and made a toast to US General William S. Harney. They named the peak for Harney, and this name was used until 2016. This expedition reported that gold could be found in the Black Hills, which spurred a gold rush into the future county area. The mining settlements that sprang up were in violation of a treaty signed with the Sioux Nation in 1868. By 1875, settlement was sufficient to justify creation of a local governing organization, so Pennington County was created on January 11, 1875, and it was fully organized by April 19, 1877. The county's boundaries were adjusted in 1877 and in 1898. The county seat was initially at Sheridan, a mining camp. (Sheridan is credited with hosting the first Federal Court west of the Missouri River.) In 1878, the county seat was moved to Rapid City. In 1923, Doane Robinson, superintendent of the SD State Historical Society, began promoting the concept of a giant sculpture carved from a Black Hills mountain. By 1927 this concept took substance, when work on

began. Shortly after the US entered
