A screenshot from L.A. Times footage of archaeologist Greg Haverstock examining the damage done to the rock. Haverstock posited that circular saws might have left the cuts and white scratches left on the rock face.

Thieves allegedly armed with power tools recently carved out ancient petroglyphs etched into a stone landscape in eastern California, removing six and damaging dozens of other carvings.

While the value of the petroglyphs has not been determined, they are sacred and priceless to the Paiute Native American Nation.

To explain more about the theft, we're joined by Greg Haverstock, archaeologist for the U.S. Bureau of Land Management in Bishop, Calif.
