Last summer, Constance Silver spent a week examining the world-renowned rock art in Utah's Nine Mile Canyon, a two-hour drive south of Salt Lake City. Tucked into the rugged Tavaputs Plateau, the place contains upwards of 10,000 images, painted and pecked onto sandstone walls. Many of them are visible from the curving, roughly graded road.
But the respected art conservator wasn't there to admire the renderings of hunters, bighorn sheep and geometric patterns. Rather, she came to study dust. More specifically, to take air samples and observe the brownish-gray clouds kicked up by an armada of oil and gas trucks as they rumbled through the canyon. After wrapping up her fieldwork, Silver stopped by the local Bureau of Land Management office in nearby Price, which oversees Nine Mile Canyon, and sought out its lone archaeologist, Blaine Miller. She informed Miller that the dust was having an "alarming effect" on the rock art and "had to be taken care of immediately."
"In your dreams," Miller said, recalling the exchange. His own concerns had been repeatedly ignored by his superiors since 2004. That was when the Bill Barrett Corporation, a Denver-based energy company, began exploratory drilling for natural gas higher up in the plateau, using Nine Mile's rutted road as the main transportation route. Silver, who specializes in restoring vandalized rock art, became adamant, according to Miller. "No, not in my dreams," she insisted. "It has to be taken care of now."
