A catfish carcass is seen in the dried-out Moreau River on the Cheyenne River Indian reservation near Thunder Butte, South Dakota August 7, 2006. The drought has killed crops, left ideal conditions for wildfires, forced ranchers to sell cattle and has evoked memories of the Dust Bowl disaster in the 1930s. Picture taken August 7, 2006.
