CCC Camp #531 - Lone Pine CA "The 'Cees', as they came to be known, were instrumental in building much of the original infrastructure of the Inyo National Forest. They were almost entirely strong, young men who needed work, a paycheck and a direction in their lives. Construction of fire stations, trails, bridges, roads and even airport runway strips were included in their duties. Lillian Guesman of Mammoth Lakes recalls:' ...they were great kids. I'd play the piano and they'd sing...we always had such a good time.'"
