Keoland reports the first ever clean of the Mount Rushmore faces was completed earlier than expected — despite some shorter days caused by the record 107-108 heat.
Lichens were growing on the faces and their roots were digging into the sculpture, which after time, could do irreparable damage. Crews say of the four heads, Washington was the easiest to clean.
Memorial Superintendent Gerard Baker said, “One of the hardest to complete was Teddy Roosevelt and I think it was because of the location and because a little more lichen in the shadows.”
Baker said, “It just affirms to us that this Harney Peak granite is very strong and it will be here for generations to come.”
