Clean-up crews break for the day after working to soak up oil from a back channel of the Yellowstone River, Sunday, July 10, 2011, near Laurel, Mont. The river is running high from late snowpack melt, making it difficult to get equipment to areas of the river and also accurately assess the effects of an estimated 1,000 barrels of oil that spilled into the river after and Exxon Mobil Corp. pipeline failed July 1 near Laurel.
