On July 1, Montana experienced its own version of the Gulf Oil spill of 2010 when the flood stage Yellowstone River damaged a submerged riverbed pipeline. In the hour that oil flowed, approximately 42,000 gallons of crude oil escaped downstream. Anytime oil mixes with water, be it fresh or saline, there are serious consequences. Due to the high water, the oil moved into 20 to 250 miles of delicate riparian habitat, making the clean-up process that much more difficult. It is estimated that only 10 to 15 percent of the oil will be recovered.
