Rocky Mountain National Park employees used pressure washers and a graffiti remover called “Elephant Snot” to scrub symbols and pictures covering 30 square feet of porous rock at the base of Twin Owls rock formation near Estes Park.
Chief ranger Mark Magnuson said the graffiti was discovered earlier this year. “It was at the base of a popular rock climbing route,” he said.
Acts of vandalism as destructive as the spray-painted graffiti are rare, Magnuson said. The last instance was two years ago, when marks were found on Eagle Cliff.
“It’s not uncommon to have visitors carve initials, names or dates on trees, usually aspen trees,” Magnuson said.
Defacing national resources is a violation of federal law. Park rangers continue to investigate the graffiti case.
