By Mark Adams

This has been a rough year for extreme fires in Flagstaff.

Before most of the U.S. Forest Service seasonal workforce was even finished with their mandatory two weeks of training, the Tunnel Fire started in one of the windiest areas of the San Francisco Peaks, during one of the windiest springs I can remember. In addition to that, it was located in the Schultz burn scar, which, at 12 years old, was primed for a fast-moving and difficult-to-contain fire due to the tall grass and kiln-dried logs that are easily receptive to any hot ember that decides to land on it. The Tunnel is what one seasoned “fire dog” referred to as a career fire — meaning that experiencing a fire like that happens once a career, if at all.

Amazingly, this fire was in mid-April, and sadly, many structures were lost, despite the huge, aggressive firefighting effort. The Tunnel Fire was unprecedented for the amount of damage caused in that short amount of time. In a typical year the Coconino averages around 175 fires, and nearly all of them are caught early and mostly go unnoticed by the average Flagstaffian. This summer we have had around 23 fires already and two of them have become career fires. Both escalated to become the No. 1 priority fires in the nation, the Tunnel and now the Pipeline Fire.

I moved to Flagstaff 28 years ago from the East Coast and like most other Flagstaff transplants, the Peaks drew me here and have been my sacred place. The Peaks are the heart and soul of Flagstaff; some might say they are the heart and soul of the state. When I moved here, I knew nothing about wildfires. The little I did know was from what I saw on the news about the Yellowstone fires of 1988. Like most people, I didn’t understand why fire managers were letting Yellowstone burn and not putting them out; I was mad that all those forests were burning. If the internet had been around, I would have been a loud critic of the Forest Service, just like so many people today commenting in online forums like they are experts in forest and fire management.

Fast forward many years later, after a long career as a Hotshot, I now better understand wildfire and the critical role it plays throughout our Western forests. All of the forests are flammable and will burn, eventually. The work we do and our efforts each year are done in hopes that they burn under our terms.

During my career, my crew and I have been emergency-shifted from one fire to another two times. The first time was on an afternoon in 2010 when I was a Mormon Lake Hotshot and we were on the Tecolote Fire in New Mexico. The radio sounded out from Incident Command: “Get Flagstaff and Mormon Lake hotshots off the mountain and come to ICP and demob immediately, there is a situation on the Peaks in Flagstaff.” In a matter of hours (which is lightning fast in federal government time), we were out of the Santa Fe Wilderness and on the road home to help fight the Schultz Fire. The next day we were briefing with fire managers at the Chevron station on Highway 89. We would be deployed behind the homes of Timberline and tasked with doing whatever we could to protect them.

History repeated itself this week. While on the Cerro Bandera Fire south of Grants, New Mexico, I received a text from Flag Dispatch of a new start. These texts come daily and normally I read them and say to myself, “Oh, they’ll catch that one” — because we do 98% of the time. This time was different. Upon checking the text, I immediately realized this one could be a problem — it’s windy and it’s in a bad spot. After making a few phone calls, once again my crew and I were quickly released and on the way back home to protect the mountain we and so many others love so much. We made it to the fire seven hours after it was first reported, lightning fast considering we started that day in a different time zone.

Luckily that night we were able to help others piece together a plan and save many homes through quick action and, ironically, having the already burned ground of the Tunnel Fire helping us. Had that fire scar not been there, the Pipeline Fire would have destroyed many more homes than the Tunnel Fire had.

The next few days, grueling work was put in by my crew and many other crews from around the nation. I am forever grateful to the three Hotshot crews from California that were with us on the ridge below Fremont Peak. Ninety people hiked in and out every day, working some tough ground that spanned from 8,500 to 12,000 feet in elevation. The air was thin, the hazards were too numerous to count and if someone got hurt, medical extraction would be challenging. The alternative to this option was not good. Had we not been up to the work, the fire would have continued to the west and with the strong westerly winds gone, it would have torched the entire mountain. All of Flagstaff would have been buried under sandbags for the foreseeable future.

Flagstaff dodged another bullet. We got lucky — lucky the firefighting resources were available, lucky they recognized the situation, lucky we were willing to accept the risk of injury or worse. It’s coming. It’s only a matter of time. All of the Peaks, minus the rocks, are flammable and will burn someday.

End of story.

Recognizing and accepting this will only help to protect our Peaks. I say this because we have altered the natural cycle of fire for far too long. Now we have one of the most sacred places in the Southwest that is primed and more than ready for a catastrophic fire. Our challenge is to ensure that it doesn’t burn all at once and try to stay as close to the natural cycle as possible. And that natural cycle includes stand-replacing fires. We have a long way to go in protecting not only the Peaks but our forests in general, and it is time that we wake up and do what needs to be done. Everyone talks a good game, but we all can do more to ensure that we have healthy ecosystems to live in for generations to come.

There are ways that we, as a community, can limit the catastrophic results of the Big One:
1. Allow for day use only on the Peaks and Dry Lake Hills near Highway 89, 180 and across Forest Road 418.
2. Follow all campfire restrictions.
3. Educate the influx of out-of-towners moving here, often unaware of our wildfire-dependent and prone ecosystem.
4. Do everything in your abilities to prepare your home/property for wildfire. The 10 years you prepare before a fire are far more important than the 10 minutes or even hours before a fire — no matter how many engines, crews, airtankers and helicopters are available.
5. Support and obey any forest closures and don’t whine about it!
6. Get used to smoke! Support aggressive, forward-thinking fire management, including managing fires under the right conditions on the Peaks and across the forest.
7. Reward and support active fire and forest management, including prescribed burning, even if there is an occasional bad outcome (99.8% of all prescribed fires are successful).
8. Question managers that do not take risks, by choosing the safe route — putting all forest fires out small, never managing a fire for resource benefit and not conducting as many prescribed fires as possible. They are just kicking the can down the road.

The Peaks are going to burn again and I would much rather they burn when we say so. Not when a campfire or burning toilet paper decides to get one going in the wrong spot on the wrong day. The choice to manage a fire or light a torch for prescribed fire is not one that we take lightly, the responsibility is huge! Things sometimes go wrong despite the best intentions. But the alternative of doing nothing has only one outcome and it’s not good.

Remember, it’s not if, it’s when.

Firefighting classified as carcinogenic to humans

We asked scientists how the findings apply to wildland firefighters

The International Agency for Research on Cancer (IARC), the cancer agency of the World Health Organization (WHO), has evaluated the carcinogenicity of occupational exposure as a firefighter.

A Working Group of 25 international experts, including 3 Invited Specialists from 8 countries was convened by the IARC Monographs program for a meeting in Lyon, France.

After thoroughly reviewing the available scientific literature, sufficient evidence led the Working Group to classify occupational exposure as a firefighter as carcinogenic to humans.

A summary of the final evaluations has now been published. The detailed assessment will be published in The Lancet Oncology in 2023 as Volume 132 of the IARC Monographs.

Evidence for cancer in humans 
The study found that occupational exposure as a firefighter causes cancer. There was sufficient evidence for cancer in humans for mesothelioma and bladder cancer.

There was limited evidence for cancer in humans for the following cancer types: colon cancer, prostate cancer, testicular cancer, melanoma of the skin, and non-Hodgkin lymphoma.

Strong mechanistic evidence 
The evaluation of the mechanistic evidence was based on exposures associated with fighting structure and wildland fires. There was strong mechanistic evidence in exposed humans that occupational exposure as a firefighter exhibits 5 of the 10 key characteristics of carcinogens: “is genotoxic”, “induces epigenetic alterations”, “induces oxidative stress”, “induces chronic inflammation”, and “modulates receptor-mediated effects”.

Exposure of firefighters
Firefighters are exposed to a complex mixture of combustion products from fires (e.g. polycyclic aromatic hydrocarbons, volatile organic compounds, metals, and particulates), diesel exhaust, building materials (e.g. asbestos), and other hazards (e.g. heat stress, shift work, and ultraviolet and other radiation). In addition, the use of flame retardants in textiles and of persistent organic pollutants (e.g. per- and polyfluorinated substances) in firefighting foams has increased over time.

This mixture may include many agents already classified by the IARC Monographs program in Group 1 (carcinogenic to humans), Group 2A (probably carcinogenic to humans), and Group 2B (possibly carcinogenic to humans). Dermal exposure, inhalation, and ingestion are common routes of exposure, and biomarker studies among firefighters have found enhanced levels of markers of exposure to polycyclic aromatic hydrocarbons, flame retardants, and persistent organic pollutants.


Most studies of firefighter health evaluate structural firefighters. We asked Dr. Kenny Fent and Dr. Kathleen Navarro of the National Institute for Occupational Safety and Health (NIOSH) questions about how these findings apply to wildland firefighters. Here is their joint response:


Summary of IARC Evaluation for Wildland Firefighters
The IARC evaluation of Occupational Exposure as a Firefighter included a review of the available scientific literature on occupational exposures, cancer epidemiology and the key characteristics of carcinogens. The evaluation did not differentiate between structural and wildland firefighters in making the determination of carcinogenicity. This is because the working group was not able to differentiate structure fire exposures (and other exposures) from wildfire exposures for firefighters in at least some of the cancer cohort studies that were included the evaluation.

In addition, many of the studies that provided the evidence of carcinogenicity included the evaluation of the key characteristics of carcinogens (intermediate health outcomes on the pathway to cancer). These included studies of wildland firefighters working on wildfires and prescribed fires.

Lastly, the exposure studies reviewed supported that both structural and wildland firefighters were exposed to similar types of carcinogens. As a result, the definition of “occupational exposure as a firefighter” for the IARC evaluation was kept broad and included a variety of hazards resulting from fires (e.g., structure, wildland, and vehicle fires) and other events (e.g., vehicle accidents, medical incidents, hazardous material releases, and building collapses).

Is mesothelioma only caused by exposure to asbestos, and are wildland firefighters generally exposed to it?
Yes, mesothelioma is caused by exposure to asbestos. Asbestos exposure is generally rare among wildland firefighters, with the exception for wildland firefighters who commonly encounter built environments (especially buildings constructed before the 1970s), areas with contamination (e.g., Libby, MT) or naturally occurring asbestos. A past NIOSH Health Hazard Evaluation reported that exposure to total asbestos fibers in air were less than the lowest occupational exposure limits while conducting a prescribed burn. However, the highest concentrations measured were during tasks with greater plant and soil disturbance and where water was not used (e.g., fire line construction and dry mop-up).


Dr. Kenny Fent leads the National Firefighter Registry at NIOSH and was the chair of the exposure characterization subgroup for the IARC working group.

Dr. Kathleen Navarro leads the Wildland Firefighter Safety and Health program at NIOSH and was a Representative of a national health agency for the IARC evaluation.

Names released of four first responders killed in New Mexico helicopter crash

The four first responders that died Saturday July 16 when a Bernalillo County Sheriff’s Office helicopter crashed northeast of Albuquerque, New Mexico have been identified: Undersheriff Larry Koren, Lieutenant Fred Beers, Deputy Michael Levison, and Rescue Specialist Matthew King. They were the only personnel on board.

All worked for the Sheriff’s Department except for Mr. King who was with the Bernalillo County Fire Department.

The Sheriff’s Department said in a news release July 17 that the “Metro 2” helicopter and its crew were assisting with the East Mesa Fire, providing bucket drops and other air logistics needs to fire crews on the ground.

This article was first published on Fire Aviation.

A pilot died Friday in the crash of an air tanker in Northeast Portugal.

In a message on his official Twitter account, Portuguese Prime Minister António Costa said, “It was with great dismay that I became aware of the death of the pilot who operated an aircraft that crashed this afternoon….I send my deepest condolences to family and friends.”

The Air Tractor AT-802AF Fire Boss went down near the town of Torre de Moncorvo after scooping water on the Douro river. The pilot was the only person on board the single engine air tanker that had departed from Viseu-Gonçalves Lobato Airport (VSE/LPVZ). Photos show that the aircraft was severely damaged. Joao Sousa, mayor of the town of Foz Coa where the incident took place, told Lusa news agency the pilot was pronounced dead at the scene.

The aircraft was operated by Titan Aerial Firefighting which has offices in Spain. The company announced on Saturday that the pilot was André Serra, from Agromontiar.

“On behalf of the whole company, friends and colleagues say goodbye to you,” they wrote. “We offer our deepest condolences to the relatives of André, a great professional and better person who has left us too soon. Rest in peace.”

Our sincere condolences go out to the family, friends, and co-workers of Mr. Serra.

Thanks and a tip of the hat go out to Gerald.

Once thought to be basically immortal, sequoias are now dying in droves

(Quote from Kyle Dickman’s article in Outside)

Kyle Dickman has written a must-read article for Outside magazine about how the largest trees on Earth which can live for more than 3,000 years, are being increasingly affected in recent years by fire. It was published this week at the magazine and covers how  management of the giant sequoias in Yosemite National Park and other areas in the Sierras has affected the vulnerability of the huge mature specimens in the groves.

Mr. Dickman is a former member of the Tahoe Interagency Hotshot Crew and spent five seasons fighting fires. He wrote the book “On the Burning Edge: A fateful Fire and the Men Who Fought It“, which is about the Granite Mountain Hotshots and the fire where all but one of them died in 2013, the Yarnell Hill Fire.

The article frequently mentions Mr. Dickman’s brother, Garrett, who is the Forest Ecologist at Yosemite and has been heavily involved in managing and attempting to save the giant sequoias. The piece is extremely well written. You can read the entire article at Outside.

Below are a few excerpts:


“What nature’s doing isn’t natural,”  [said Joe Suarez, the Arrowhead Hotshots superintendent]

Garrett [Dickman] and Christy Brigham, the director of science at Sequoia and Kings Canyon National Park, are standing in front of an outhouse that firefighters saved from the Castle Fire, sitting in the patchy shade of a 2,000-year-old dead tree that they did not. Firefighters protect life and property before all else—even holes to shit in, so long as they have walls around them. Listening to the two compare notes on their jobs makes clear that the fate of giant sequoias is almost entirely in the hands of a few middle managers, working at a few select parks, who navigate arcane environmental laws and a financing system cobbled together with public grants. If sequoia death is a product of American gridlock, sequoia survival will happen because of the tenacity of a few individuals.

The current drought is more intense than any experienced in California in 1,200 years.

“These next couple of years could be bad in ways we haven’t experienced yet,” Garrett says. The Park Service knows what’s coming. After 60 years trying to walk backward by managing their lands to be what conservationist Starker Leopold, who devised the agency’s guiding philosophy from the late 1960s until 2021, called “vignettes of primitive America,” the Park Service has changed course to officially recognize that park managers must intervene in ways considered antithetical to their mission two years earlier. The new policy asks the public to open its mind to everything from mechanical thinning to very limited logging. “We saw how it goes when you don’t do anything,” Christy says. “It goes terribly. It goes thousands of 2,000 year old trees burned up in an instant.”

“We don’t get to have nice things anymore,” Garrett says.”

“The Clean Water Act. The National Environmental Policy Act. The National Historic Preservation Act. The Threatened and Endangered Species Act. Fantastic laws all of them,” Christy says. “But they were built at a time when the main threat was people doing bad things—logging, mining. Now the main threat is inaction. Bureaucracy is slow. Wildfire is fast. And bureaucracy needs to get a hell of a lot faster if we want to persist and not lose everything we’ve got left.”
