The Yellowstone Fires of 1988
In the summer of 1988, dozens of fires burned 793,880 acres of Yellowstone National Park, about 36 percent of the entire park. The largest firefighting effort in US history to that point could not stop them; autumn snow finally did. The fires transformed public understanding of fire's role in western ecosystems.

Key facts
What happened
The summer of 1988 was the driest in Yellowstone's recorded history. Early-season fires were allowed to burn under the park's natural-fire policy, as they had for 16 years without incident, but by mid-July fire behavior became unprecedented. On August 20, remembered as Black Saturday, winds gusting to 70 mph pushed fires across more than 150,000 acres in a single day.
More than 25,000 firefighters and 4,000 military personnel cycled through the effort. The North Fork Fire nearly overran the Old Faithful complex on September 7. Season-ending snows in September and November finally quieted the fires.
Why it matters
Media coverage declared Yellowstone destroyed, but the ecosystem rebounded dramatically: lodgepole pine, whose serotinous cones open with heat, reseeded vast areas within a few years. The 1988 fires became the most-studied fire event in ecology and reshaped federal fire management, confirming that decades of total suppression had built dangerous fuel loads.
Frequently asked questions
How much of Yellowstone burned in 1988?
About 793,880 acres, roughly 36 percent of the park, burned in a mosaic pattern. The greater Yellowstone area total was about 1.4 million acres.
Did the 1988 fires destroy Yellowstone?
No. The burns created a mosaic of habitats, and lodgepole forests reseeded naturally within a few years. Ecologists now regard 1988 as a demonstration of fire's natural role, and visitors today see young forests across the old burn scars.
Did anyone die in the Yellowstone fires?
No one died inside the park. Two firefighters died in the greater area: one struck by a falling tree and a pilot killed in a crash.
