Wind-carved striations and animal tracks sre seen on dunes from tailings behind fences and warning signs near Randsburg, Calif., Jan. 18, 2008. In the century since prospectors abandoned the mountains of tailings near beside 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)
