 The Mink fire started in Bridger-Teton National Forest from lightning on July 11, and burned north following the Yellowstone River valley, after firefighters forced the fire away from private lands.The Mink fire eventually burned sections inside the park after July 23, but was deemed to be a low risk since it was in a very remote section of the park.The third largest fire was the Huck fire, which started after a tree fell on a power line on August 20 near Flagg Ranch.
