Sacred to the Lakota, the Black Hills was part of the land reserved for them in the Fort Laramie Treaty of 1868. However, the tide of prospectors seeking their fortune in the Black Hills was difficult to stem. Members of the 1874 Custer expedition, lead by Gen. George Armstrong Custer, found gold. In 1875, scientists Henry Newton and Walter Jenney conducted an expedition and confirmed the rumors. By 1876, the trickle of prospectors and settlers coming to the Black Hills was a flood.
