Oregon is closing out what will be remembered as its most destructive wildfire season on record, with nearly 2.4 million acres burned as of mid-October 2026. That figure surpasses the previous state record of 1.9 million acres set in 2024, and it represents more than one-quarter of the roughly 9 million acres burned nationally this year.

The Season's Largest Fires

Two major fire complexes defined the summer in eastern Oregon:

  • The Rowe Creek Complex — a cluster of seven fires that merged north of Prineville and burned toward the John Day River — scorched approximately 373,927 acres, making it the fifth-largest fire in Oregon since 1992.
  • The Coleman Creek Fire, burning east of the Harney County seat of Burns, consumed approximately 308,863 acres — the sixth-largest on record — and blackened 40 miles along the southern edge of U.S. Highway 20.

Cattle ranchers and agricultural operators in Harney County were among the hardest hit. Tom Sharp, who leads the North Harney Rangeland Fire Protection Association (RFPA), said the losses to rangeland — the economic foundation of the region — cannot be overstated. One of his RFPA's military-surplus Humvees, repurposed for firefighting, was damaged fighting the Second Flat Fire, which also topped 100,000 acres in late July.

The Oregon-Idaho-Nevada Fire Corridor

Research has consistently identified the Oregon-Idaho-Nevada border region as one of the largest concentrations of the country's fastest-moving fires. The geographic and climatic conditions — hot summers, cured grasses, and persistent east winds — create a corridor where fires can travel extraordinary distances in short timeframes. That dynamic was on full display during the peak of the 2026 season.

The Second Flat Fire, for instance, was lightning-caused and spread rapidly through sage and pine in southeastern Oregon in late July, requiring RFPA volunteers — mostly ranchers — to deploy their own equipment alongside state and federal resources.

Season Timing and Moderation

Despite the record acreage, NIFC meteorologist Jim Wallmann noted that well-timed rainfall in the mountains of Idaho and Montana tempered the season somewhat in those states and helped bring an earlier slowdown than initially forecast. The peak four-week period from mid-July to mid-August was, by Wallmann's account, among the busiest stretches he had seen in years at NIFC.

Statewide, cooler and wetter weather has since pushed fire activity to near-historic lows, and multiple large fires are now in mop-up or monitoring phases. However, the scale of what burned this season will shape forest policy, rangeland management, and community resilience conversations in Oregon for years to come.

Mt. Hood Fires Near Final Containment

The Grasshopper Fire and Austin Fire — both on the Mt. Hood National Forest — are now 98% contained at 93,972 and 12,888 acres respectively. Forest closures remain in place while emergency personnel continue suppression, repair, and hazardous tree removal operations. The Mt. Hood National Forest lifted general fire restrictions earlier this month ahead of incoming rain and cool weather, though area closures at both fire footprints are still strictly enforced.

Residents and visitors planning to access Hood River, Wasco, or Clackamas County recreation areas should check the Mt. Hood National Forest website for current closure orders before traveling.
