In this photo taken Tuesday, March 4, 2014 Tim Amavisca, 38, and his daughter Hailey, 15, use a sluice box that's used to trap gold flakes on a textured rubber mat as they search for gold along the Bear River near Colfax, Calif. Amavisca is among the amateur prospectors that have flocked to the Sierra Nevada foothills that, due to the historic drought, are taking advantage of the lower water levels to search for gold in riverbeds that have been unreachable for decades.(AP Photo/Rich Pedroncelli) less
