One of the country’s most famous landmarks probably will keep its name, despite a recent attempt to rename it. A California resident in July 2020 proposed renaming Mount Rushmore to Igmu Tanka Paha, a Lakota Sioux name that means Cougar Mountain, according to the federal Board on Geographic Names.
Anyone can submit a proposal to rename a geographic feature, but the board tends to be conservative when considering such requests, said Jennifer Runyon, a senior researcher with the board. A national landmark like Mount Rushmore introduces additional complications, and a name change would likely require overwhelming public support. Additionally, the board only has the power to rename the mountain itself — not the national monument that shares its name.
