The winter rains had been more than generous this year, and this part of the Sonoran desert, Soza Canyon on the far eastern edge of the Rincon Mountains, was alive with flowers. Scrawny, suntanned, and weathered, Amos was more than middle-aged and still remarkably fit. Even so, the sixty or seventy pounds he carried in the sturdy pack on his shoulders weighed him down and had him feeling his sixty-plus years. He had started the day by picking up several top-notch arrowheads. He slipped several of them into the pockets of his jeans rather than risk damaging them as the load in the pack increased over the course of the day. The one he considered to be the best of the lot, he hid away inside his wallet, congratulating himself on the fact that his day was off to such a great start. In the course of the morning, he located several geodes. The best of those was a bowling-ball-sized treasure that would fetch a pretty penny once it joined the growing collection of goods that he and his foster son, John Lassiter, would offer for sale at the next available gem and mineral show.
