In the early morning hours of Aug.19, a fuel tanker truck lost control and rolled over near mile marker 16 on U.S. Hwy 191, a section of highway that runs through the western portion of Yellowstone National Park, according to a press release from the Public Affairs Office.

An estimated 4,800 gallons of unleaded fuel spilled as a result, and it is unknown if any entered nearby Grayling Creek.
