At its peak the 2013 Rim Fire east of Sonora, California, had over 5,000 personnel assigned. At over 257,000 acres it stands today as the fourth largest wildfire in the recorded history of California, 30 miles wide, west to east. Most of the blaze was in the Stanislaus National Forest but it spread into Yosemite National Park where it burned almost 79,000 acres of the Park’s back country, but never made it to the most visited area, Yosemite Valley.

The Ferguson Fire which as been burning for 10 days already has 2,900 personnel assigned and reached 30,000 acres Saturday. So far it has not destroyed any structures. As large as it was, the Rim Fire burned a surprisingly small number of structures — 11 homes, 3 commercial buildings, and 98 outbuildings. But if the Ferguson Fire grows east in a big way, several communities would be at risk, including El Portal, Foresta, Yosemite West, and possibly Wawona.

For the last week the Ferguson Fire has been slowed by inversions that typically do not break until mid-afternoon, after which it has been adding several thousand acres each day. If the weather changes and brings a strong wind with a westerly component, the complexion of the fire will change dramatically. In two days in mid-August, the Rim Fire burned nearly 90,000 acres.

Saturday night only four miles separated the Ferguson Fire from the footprint of the 2013 Rim Fire. If it does burn into it, the resistance to control should decrease, allowing firefighters a better chance to stop it in that area. If the north end of the Ferguson Fire spreads northeast three miles it will burn into Yosemite National Park. From that point, Yosemite Valley would be 13 miles to the east.

The Fire History map the Incident Management Team uploaded to InciWeb on July 21 is very cluttered and extremely difficult to decipher, but there have been some fires in the last 20 to 40 years years north of Highway 140 and east of the Ferguson Fire which, to a certain extent, may help firefighters a bit.

Researcher looks at the effects of fuels management and previous fire on Rim Fire severity

In a November 13 webinar at 1 p.m. MST Jamie Lydersen will present her findings about how the effects of fuels management and previous fire affected the severity of the Rim Fire that started on the Stanislaus National Forest and burned into Yosemite National Park.

It seems intuitive to those who study wildland fire that a reduction in fuels will result in a decreased rate of spread and fire severity for the next wildfire, but it’s always good to have data that can confirm or refute long-held beliefs.

Here is a description of Ms. Lydersen’s research.

The 255,000 acre 2013 Rim Fire created an opportunity to study fuels treatment effects across a large forested landscape in the Sierra Nevada. We assessed the relative influence of previous fuels treatments (including wildfire), fire weather, vegetation and water balance on Rim Fire severity. Both fuels treatments and previous low to moderate severity wildfire reduced the prevalence of high severity fire. Areas without recent fuels treatments and areas that previously burned at high severity tended to have a greater proportion of high severity fire in the Rim Fire. Areas treated with prescribed fire, especially when combined with thinning, had the lowest proportions of high severity.

Jamie Lydersen is an associate specialist in the department of environmental science, policy and management at the University of California, Berkeley and a contractor for the Pacific Southwest Research Station, USDA Forest Service.

Deaths of two witnesses result in dropped charges against person accused of starting Rim Fire

After being indicted by a Federal Grand Jury in August, 2014, the unexpected deaths of two witnesses caused the federal government this week to move to dismiss the charges against 32-year-old Keith Matthew Emerald for starting the 2013 Rim Fire that burned 257,000 acres in the Stanislaus National Forest and Yosemite National Park in California.

The government’s motion to dismiss the charges characterized one witness as critical to the case and stated that he had been expected to provide trial testimony regarding his discussions with Mr. Emerald shortly after he had been rescued from the vicinity of the Rim Fire’s origin. That witness died in a workplace accident in February. The second witness was the helicopter pilot who first responded to the Rim Fire. That witness had been expected to testify about the initial response to the Rim Fire and the rescue of the defendant very close to the Rim Fire’s point of origin. That witness died in March of cardiac arrest.

These witnesses’ prior statements now are considered hearsay and cannot be used as evidence at trial.

In its motion to dismiss the charges, the government stated that it had reassessed the case in light of the loss of this anticipated trial testimony and determined that without that testimony it was unlikely to prove the charges in the case beyond a reasonable doubt to the unanimous satisfaction of a trial jury. Accordingly, it was in the interests of justice to dismiss the case.

According to court documents, Mr. Emerald was rescued by a CAL FIRE helicopter from the extremely remote Clavey River Canyon area of the Stanislaus National Forest near the origin of the Rim Fire about an hour after the fire was reported. He was carrying bow hunting equipment with him and advised authorities that he had been on a solo hunting trip.

The CAL FIRE crew turned Mr. Emerald over to a U.S. Forest Service Fire Prevention Technician, who was not a law enforcement officer. He was later given a ride out of the forest by a government employee, but no one asked him for any identification. Investigators believe they were able to overcome that oversight. Later they applied for a search warrant for Mr. Emerald’s house and his vehicle, expecting to possibly find evidence in his computer, cell phone, backpack he was carrying that day, or elsewhere on the premises.

During the extensive investigation and multiple interviews with Mr. Emerald, he told investigators several different versions of how the fire started, including:

  • Illegal pot growers;
  • He inadvertently started a rock slide, causing rocks to collide, creating sparks, which started the fire;
  • He said he started a campfire and burned some trash in it. The burning trash blew into vegetation, starting the fire which escaped.

Mr. Emerald later recanted the campfire story.

Investigators ruled out all possible fire causes other than “incendiary/intentional fire start by human”, the court documents revealed.


A film: “The Fire Next Time”

The producer describes this film:


“In this 13-minute film, filmmakers Stephen Most and Kevin White examine how problematic policies, fuel build-up, and climate change have endangered America’s forests. When the Rim Fire burned 256,000 acres of the Stanislaus National Forest and Yosemite National Park in 2013, it exposed the impacts that high intensity wildfires are having on watersheds, wildlife, and carbon storage. It also forged a coalition of environmentalists, loggers, scientists, officials, and land managers who are responding to this megafire and recognize the need to forestall the next one. “The Fire Next Time” is a precursor to Filmmakers Collaborative’s feaure-length work-in-progress, “MEGAFIRE at the Rim of the World.” For more information, visit”

Possible wildfire suppression scam

From the Rapid City Fire Department:

Scam Alert: Investigators for the RCPD would like to inform the public of a possible scam targeting local businesses. An individual has been soliciting donations for an organization called ‘Atta Katta Wildland Fire Suppression.’ The Rapid City Police Department has reason to believe that this organization is fraudulent. If you’ve been solicited for a donation to this organization, please contact Sgt. Warren Poches at 394.4134.

Moonlight fire scandal continues to grow

The accusations of prosecutorial abuse, fraud, and government coverups related to the 2007 Moonlight Fire in northern California are gathering more nationwide attention. Here is how an article by Kathleen Parker begins:

First there’s the spark, then the conflagration, followed by the litigation and then, surely, the movie. Call it “Moonlight Fire,” and prepare to suspend disbelief. The story is a doozy — a tale of corruption, prosecutorial abuse, alleged fraud upon the court, and possible government cover-ups in the service of power and greed. All the script needs is a Forest Service employee urinating on his bare feet in his lookout tower just as the fire was beginning.


This is what a real-life ranger discovered when she went to the tower to pick up a radio for repair. She also reported spotting a small glass pipe and smelling marijuana. As for the urinary exercise, the lookout said he was treating his athlete’s foot. But of course.

So goes one of the more colorful anecdotes surrounding the 2007 California wildfire that burned up to 65,000 acres — 45,000 of them on federal land — in the northern Sierra Nevada Mountains…

Jonathan Keim also wrote about the debacle for the National Review.

Study on the Rim Fire recommends more interagency prescribed fires

Excerpts from an article a KSBW:

A fierce wildfire that scorched part of Yosemite National Park burned less intensely in places that had fires in recent years – a finding that researchers said Wednesday supports a belief that controlled burning often curtails extreme fires.

The U.S. Forest Service study focused on areas of the Rim Fire that burned 400 square miles in Stanislaus National Forest, Yosemite’s backcountry and private timber land.

It was the largest fire in the recorded history of the Sierra Nevada. It destroyed 11 homes and cost more than $125 million to fight.

Areas hit by the Rim Fire within Yosemite had burned within 14 years and experienced less intense flames, said U.S. Forest Service Pacific Southwest Research Station, which authored the study.

Researchers recommend that forestry agencies with shared borders and interests combine their efforts to conduct controlled burns during moderate weather conditions, giving them the best chance for to avoid massive high-intensity fires.

10-year high for people charged with lighting fires in Victoria

From The Age in Australia:

The number of charges for lighting fires on days of total fire ban or during bushfire danger periods has reached a 10-year high, as police crack down on the foolishness that has sparked destructive blazes since Black Saturday.

There were 227 charges for lighting a fire on a total fire ban day or in a fire danger period last year, an increase of more than 17 per cent compared to the previous year and more than five times the number recorded in 2010-11.

While most of the fires raging in Victoria this week are believed to have started because of lightning strikes, Emergency Services Commissioner Craig Lapsley said some of the 350 blazes burning on Wednesday would have been caused by people ignoring the volatile conditions.

“It wouldn’t all be lightning. There would have been some foolish behaviour…

Homes burn in Victoria bushfire

Four homes burned in a bushfire in the Creighton’s Creek area of Victoria. State Control Centre spokesperson Leigh Miezis said 1,500 firefighters are currently battling the blaze.

The video below was filmed by Jacob Haddrill in Creightons Creek. He saved his cattle but his feed and fencing was damaged in the fire.
