An archaeologist claims that someone has been secretly cleaning a Utah tourist attraction with a high-pressure washer, damaging the world-famous rock art in Nine Mile Canyon.
The biggest issue is dust from hundreds of industry vehicles. Miller says dust is obscuring many ancient artworks. “We suspect it’s being damaged, but we don’t have scientific studies yet,” she said.
But the most famous one, the Great Hunt Panel, seems brighter, more colorful, less dusty, even compared with art a few feet away. Miller believes someone has washed the Great Hunt Panel at least two or three times with high-pressure equipment.
“I think it’s bad. I think it has the potential to really damage the site,” she said.
