Twenty-five years ago, Yellowstone National Park suffered the worst fires in its history.

Multiple fires raged in and around the park, beginning in early June and continuing through late September. A total of 51 fires were recorded during the summer, with nine being human-caused and 42 being sparked by lightning.

The fires affected 793,880 acres — about 36 percent of the park — and, on Sept. 8, forced the closure of Yellowstone to all but emergency personnel for the first time in the park's history.

About 25,000 people fought the fires, which cost $120 million to suppress.
