In one photograph, Dr. Jonathan Bourne crouches over an ancient wooden bow sticking out of a melting glacier in the High Sierra. In another picture, he is digging the bow out of the ice with a rock.
The photos of Bourne, an anesthesiologist at Mammoth Hospital, appeared on a hiking-club website — and soon, he had visitors.
Federal agents searched Bourne's mansion in December, recovering roughly 30,000 ancient items they believe were unlawfully taken from hundreds of public land sites across the West: stone mortars, glass beads, projectile points and pendants. They also seized logbooks containing details of his archaeological finds.
