The 10 Deadliest Wildfires in American History and the Devastating Trails They Left Behind
Wildfires remain a national concern each year, especially across the West, where long fire seasons and dry conditions keep emergency agencies on alert. Looking back at the 10 deadliest wildfires in American history shows how fires in states from Wisconsin to California left lasting damage, with death tolls recorded by state agencies, federal records, and historical accounts.
1. Peshtigo Fire, Wisconsin, 1871
The Peshtigo Fire killed an estimated 1,152 to 2,500 people on October 8, 1871, according to the Wisconsin Historical Society, making it the deadliest wildfire in U.S. history. The fire burned about 1.2 million acres across northeastern Wisconsin, including Peshtigo, Marinette, and nearby settlements.
In Wisconsin, the fire destroyed much of the town of Peshtigo and hit door-to-door communities along the Peshtigo River. The full death toll has never been confirmed because many records were lost in 1871, and some victims were never identified.
Historians with the Wisconsin Historical Society said drought, logging slash, high winds, and small land-clearing fires all contributed to the disaster. The same date, October 8, 1871, also coincided with the Great Chicago Fire, which drew far more national attention at the time.
For visitors today, Peshtigo remains tied to the fire through the Peshtigo Fire Museum and cemetery, where mass graves still mark the scale of the loss. The event is still cited by fire historians as a turning point in how the country remembers wildfire risk.
2. Cloquet Fire, Minnesota, 1918
The Cloquet Fire killed about 453 people in northeastern Minnesota in October 1918, according to the Minnesota Department of Natural Resources. The fires burned roughly 250,000 acres and swept through Carlton County, Cloquet, Moose Lake, and Kettle River.
The local impact was concentrated in timber and rail communities, where entire neighborhoods were destroyed in a matter of hours on October 12, 1918. Minnesota records show hundreds were injured, but a complete list of all damaged properties has not survived in one public statewide inventory.
State historical accounts say extreme drought, slash left by logging, and powerful winds drove multiple small fires into one fast-moving front. The disaster happened during the 1918 influenza pandemic, which complicated emergency response and sheltering in affected Minnesota communities.
Residents and travelers in the region still encounter memorials in Cloquet and Moose Lake that document the 1918 losses. The Minnesota Historical Society has preserved photographs and firsthand accounts that keep the fire central to the region’s public memory.
3. Maui may recall Lahaina, but California’s Camp Fire ranks among the deadliest, 2018
The Camp Fire killed 85 people in Butte County, California, after igniting on November 8, 2018, according to the California Department of Forestry and Fire Protection, or Cal Fire. It destroyed more than 18,000 structures, including much of Paradise, and burned over 153,000 acres.
In local terms, the fire erased large sections of Paradise, Concow, and Magalia, turning roads into evacuation bottlenecks. Cal Fire and Butte County confirmed the death toll, while later rebuilding totals shifted as insurance, permitting, and reconstruction moved forward.
Cal Fire determined the fire was caused by electrical transmission lines owned by Pacific Gas and Electric. In June 2020, PG&E pleaded guilty to 84 counts of involuntary manslaughter in Butte County Superior Court tied to the fire, while one victim was not included in that plea count.
For California residents, the Camp Fire remains a benchmark for evacuation planning, utility oversight, and rebuilding after mass loss. Paradise has reopened schools, homes, and businesses, but state and county agencies continue to cite 2018 as a defining year in wildfire policy.
4. Hinckley Fire, Minnesota, 1894
The Hinckley Fire killed about 418 people on September 1, 1894, according to the Minnesota Historical Society and state records. It burned at least 200,000 acres in Pine County and destroyed Hinckley, Mission Creek, Sandstone, and nearby settlements.
In eastern Minnesota, survivors famously escaped by boarding trains that pushed through flames and smoke out of Hinckley. The total number of destroyed homes and businesses was enormous for the era, though 1894 records do not provide one universally accepted statewide count.
Historical accounts point to drought, logging debris, and strong winds as the main causes behind the fire’s explosive spread. The Hinckley Fire Museum says heat was so intense that some people survived only by sheltering in wells or wet ground near the Grindstone River.
Today, Hinckley’s fire museum and monument preserve names, artifacts, and timelines from the 1894 disaster. The event remains one of Minnesota’s defining wildfire tragedies and is regularly cited in regional fire education and local heritage tourism.
5. Yarnell Hill Fire, Arizona, 2013
The Yarnell Hill Fire killed 19 members of the Granite Mountain Hotshots on June 30, 2013, according to the Arizona State Forestry Division and the official Serious Accident Investigation Report. The fire burned about 8,400 acres near Yarnell in Yavapai County.
For Arizona, the deadliest impact was concentrated in one firefighting crew from Prescott, making it one of the nation’s worst firefighter losses since 9/11. The state confirmed 19 fatalities, and Yarnell also saw more than 100 homes destroyed as the fire moved through the area.
The official investigation said the fire shifted rapidly under changing weather and thunderstorm outflows. The report did not assign blame to the crew members, but it documented communication gaps, fuel conditions, and sudden fire behavior that trapped the hotshot team.
Residents now see the Granite Mountain Hotshots Memorial State Park as the main public site tied to the fire. The Yarnell Hill Fire continues to shape firefighter training in Arizona and nationwide, especially around weather awareness and escape route planning.
6. Griffith Park Fire, California, 1933
The Griffith Park Fire killed 29 people in Los Angeles on October 3, 1933, according to the Los Angeles Fire Department and city historical records. The blaze injured more than 150 others and burned in Griffith Park, where many workers were on site that day.
The local toll fell heavily on workers from relief crews during the Great Depression, many of whom were clearing brush in steep terrain. Los Angeles records say shifting winds and limited escape options contributed to the high death count inside the park.
City accounts and historical reviews said extreme heat and sudden fire spread trapped workers in canyons and on ridgelines. The fire was not one of California’s largest by acreage, but its 29 deaths keep it among the deadliest in the state’s history.
For Angelenos, Griffith Park remains a major public recreation area with trails, historic sites, and memorial context linked to 1933. The disaster is still referenced in city fire history because it showed how dangerous urban-edge wildland fires can become.
7. Thirtymile Fire, Washington, 2001
The Thirtymile Fire killed four firefighters on July 10, 2001, in Washington’s Okanogan National Forest, according to the U.S. Forest Service. The fire burned about 9,300 acres near Winthrop and Twisp, but the lasting focus stayed on the crew fatalities.
In north-central Washington, the deaths of four young firefighters deeply affected forest towns and federal fire operations. The Forest Service confirmed the fatalities, while later reviews and court proceedings examined command decisions made during the entrapment in a narrow canyon.
Federal investigators said drought, heavy fuels, steep terrain, and abrupt fire behavior played major roles. The aftermath led to national scrutiny, and the Forest Service revised parts of its training and operational procedures after the 2001 tragedy.
Travelers in Okanogan County still pass landscapes shaped by repeated fire seasons, and Thirtymile remains a key reference point in firefighter safety discussions. Federal agencies continue to cite the incident in training material more than two decades later.
8. Blackwater Fire, Montana, 1937
The Blackwater Fire killed 15 firefighters on August 21, 1937, in the Shoshone National Forest area near Cody, Wyoming, though it is often grouped into broader U.S. wildfire fatality history with Rocky Mountain fire disasters. Federal records place the incident in Wyoming, not Montana.
Because the fire occurred near the Wyoming side of the region, geographic labeling sometimes causes confusion in later summaries. The U.S. Forest Service’s documented death toll is 15, and that count remains the key verified figure attached to Blackwater.
Forest Service histories said dry fuels, rugged slopes, and a sudden blowup trapped Civilian Conservation Corps members and Forest Service personnel. The Blackwater Fire later became one of the central case studies in wildfire behavior research and crew safety lessons.
For readers tracking deadly fire sites, the key fact is that Blackwater’s legacy is tied to firefighter safety doctrine more than community destruction. Its lessons helped shape later federal thinking on fire entrapment and survival in mountainous terrain.
9. South Canyon Fire, Colorado, 1994
The South Canyon Fire, also called the Storm King Mountain Fire, killed 14 firefighters on July 6, 1994, near Glenwood Springs, according to the U.S. Forest Service and National Interagency Fire Center. The fire burned about 2,115 acres on steep western Colorado terrain.
In Colorado, the losses hit multiple agencies, including smokejumpers and hotshots, and deeply affected Glenwood Springs. The official fatality count is 14, and memorial trails near Storm King Mountain now mark where crews were overtaken during a sudden uphill run of fire.
Investigations found that dry brush, steep slopes, and rapidly changing fire behavior drove the entrapment. Federal reviews after 1994 made South Canyon one of the most studied firefighter fatalities in modern U.S. wildfire history.
For visitors, the Storm King Mountain Memorial Trail is one of the clearest public reminders of the danger firefighters face. The 1994 fire remains part of national training because of the documented timeline, radio traffic, and weather conditions.
10. Rattlesnake Fire, California, 1953
The Rattlesnake Fire killed 15 firefighters on November 9, 1953, near Alturas in Modoc County, according to the U.S. Forest Service and California fire histories. The victims included 14 inmates from a prison conservation camp and one California Department of Forestry employee.
In far northern California, the deaths centered on one crew working in rough country under dangerous conditions. State and federal records consistently list 15 fatalities, and the fire remains one of the deadliest single wildfire incidents for firefighters in California history.
Historical investigations said shifting winds and explosive fire movement trapped the crew while they were building line. The incident later influenced California and federal discussions about crew deployment, supervision, and emergency escape planning on active fire lines.
For the public, the Rattlesnake Fire is less widely known than the Camp Fire, but it remains important in wildfire history. It is still cited in firefighter memorial records and in discussions about how prison conservation crews were used in the 1950s.
