Idk but here's what I found on Wiki:

"Six Grandfathers" to "Mount Rushmore"

Mount Rushmore and the surrounding Black Hills (Pahá Sápa) are considered sacred by Plains Indians such as the Arapaho, Cheyenne, and Lakota Sioux, who used the area for centuries as a place to pray and gather food, building materials, and medicine. The Lakota called the mountain "Six Grandfathers" (Tȟuŋkášila Šákpe), symbolizing ancestral deities personified as the six directions: north, south, east, west, above (sky), and below (earth). In the latter half of the 19th century, expansion by the United States into the Black Hills led to the Sioux Wars. In the 1868 Treaty of Fort Laramie, the U.S. government granted exclusive use of all of the Black Hills, including Six Grandfathers, to the Sioux in perpetuity.

Six Grandfathers was a significant part of the spiritual journey taken in the early 1870s by Lakota leader Black Elk (Heȟáka Sápa, also known as "The Sixth Grandfather"), that culminated at the nearby Black Elk Peak, (Hiŋháŋ Káǧa, "Making of Owls") U.S. general George Armstrong Custer summited Black Elk Peak a few years later in 1874 during the Black Hills Expedition, which triggered the Black Hills Gold Rush and Great Sioux War of 1876. In 1877, the U.S. broke the Treaty of Fort Laramie and asserted control over the area, leading to an influx of settlers and prospectors.

Among those prospectors was New York mining promoter James Wilson, who organized the Harney Peak Tin Company, and hired New York attorney Charles E. Rushmore to visit the Black Hills and confirm the company's land claims. During a visit in 1884 or 1885, Rushmore saw Six Grandfathers and asked his guide, Bill Challis, the mountain's name; Challis replied that the mountain didn't have a name, but that it would henceforth be named after Rushmore. The name "Mount Rushmore" continued to be used locally, and was officially recognized by the United States Board of Geographic Names in June 1930.
