The decision will apply to all federal maps and publications, but South Dakota will not be required to change its own maps and signs. Governor Daugaard said he was surprised by the decision, and his chief of staff stated that the state will not go to any extra expense to implement the change. In 2014, a petition for the name change was put before the South Dakota Board on Geographic Names. Originally the state board supported the idea of a name change, but faced such backlash about the decision, that they reversed themselves. They recommended to the national board that Harney Peak retain its name.
