Aboriginal Petroglyphs Destroyed by Vandals Armed with Acid and a Drill

“To my absolute horror, I could see what kind of damage had been done…I just couldn’t believe it.”

“The vandals used a truck to get to the rock and suspects they used a power washer to remove the lichen covering the symbols before spraying acid on the paintings and drilling away the carvings with a rock bore or hammer drill.

“We have been violated, future generations have been robbed and the world has been deprived of the ancient knowledge contained within these artifacts,” Knowlton wrote in his report. “This urgent matter must follow a formal plan of action at all levels.””
