Cleanup crews work to collect fuel spilled from the towing vessel Stephen L. Colby, Nov. 29, 2013, along the shoreline of the Mississippi River. The Unified Command is working in conjunction with community volunteers to ensure all pollution is cleaned up and the environment restored to its original state after the vessel struck an unidentified submerged object, Nov. 25, 2013, and partially sank.
