Arsenic Mines

Chapman University geology student Thomas Bailey collects soil samples for later analysis from a tailing pile near an old mine near Johannesburg, Calif., Jan. 18, 2008. In the century since prospectors abandoned the mountains of tailings near this old desert mining camp, winds have carried away more than just handfuls of California history. Soil samples have revealed arsenic levels thousands of times higher than what is considered acceptable. (AP Photo/Reed Saxon)
