"their first signpost for Mount Rushmore"
is a sculpture carved out of granite featuring the likeness of four American presidents, in the region of the Black Hills
. It was created by Gutzon Borglum
and continued by his son Lincoln Borglum
. Originally known by the Lakota Sioux as 'Six Grandfathers'
it was renamed after New York Lawyer Charles E Rushmore
It is a controversial monument for Native American people because the United States forcibly took back the land from the Lakota, despite originally promising them the Black Hills in perpetuity.
