The lack of aggressive action during the early days of the Chimney Tops 2 Fire that burned more than 2,000 homes in Gatlinburg, Tennessee has ignited discussions about allowing some wildfires to spread under predetermined conditions.
National Public Radio explores how four national forests in California are modifying their fire strategy. (Less than 4 minutes.)
A weather system meteorologists are calling an “atmospheric river” is bringing massive amounts of rain and snow to California.
As a high pressure system over the west coast moves out of the way, massive amounts of precipitation are being funneled into California and Oregon. As orographic lifting squeezes the moisture out of the air mass some areas in the Sierras could receive up to two feet (24 inches!) of precipitation before this event is over. If most of it falls as snow in the mountains, the peaks in the Sierras could see up to 10 feet of snow.
It has already started, as you can see in the graphic below showing the snow received as of Wednesday morning. And the storm has just begun.
It remains to be seen how this will affect California’s five-year drought and the 2017 fire season. In 2016 the northern part of the state saw some relief from the drought, but there was not much change farther south.
Changes in human uses of the land have had a large impact on fire activity in California’s Sierra Nevada since 1600, according to research by a University of Arizona researcher and her colleagues.

Forest fire activity in California’s Sierra Nevada since 1600 has been influenced more by how humans used the land than by climate, according to new research led by University of Arizona and Penn State scientists.
For the years 1600 to 2015, the team found four periods, each lasting at least 55 years, where the frequency and extent of forest fires clearly differed from the time period before or after.
However, the shifts from one fire regime to another did not correspond to changes in temperature or moisture or other climate patterns until temperatures started rising in the 1980s.
“We were expecting to find climatic drivers,” said lead co-author Valerie Trouet, a UA associate professor of dendrochronology. “We didn’t find them.”
Instead, the team found the fire regimes corresponded to different types of human occupation and use of the land: the pre-settlement period to the Spanish colonial period; the colonial period to the California Gold Rush; the Gold Rush to the Smokey Bear/fire suppression period; and the Smokey Bear/fire suppression era to present.
“The fire regime shifts we see are linked to the land-use changes that took place at the same time,” Trouet said.
“We knew about the Smokey Bear effect — there had been a dramatic shift in the fire regime all over the Western U.S. with fire suppression. We didn’t know about these other earlier regimes,” she said. “It turns out humans — through land-use change — have been influencing and modulating fire for much longer than we anticipated.”

A report has been released by the Wildland Fire Lessons Learned Center about a dozer rollover that occurred July 2, 2016 at the Trailhead Fire on the Eldorado National Forest in California. You can read the entire report, but here’s a brief summary.
After getting unstuck from being high centered on a large stump, a dozer operator found himself off the ridge where he was building an indirect fireline, and was on a steep slope. Again he got stuck and was not able to backup, this time due to the slope which in places exceeded an 80 percent incline. At various times he was advised by two Resource Advisors, the Structure Group Supervisor, and the owner of the dozer to stay put. In the meantime another dozer with a winch was en route to assist.
Ignoring the advice, the operator continued down the slope and got into a heated argument with the owner, who then left the area. Determined to get the dozer back up to the ridge top, the operator began building a road and creating pads where he could work to push over trees that were in his way, including a 30-DBH cedar which missed by 50 feet the two Resources Advisors who had to run to get out of the way.
The incident-within-an-incident finally came to an end, at least temporarily, when the dozer rolled over onto its side. The operator escaped with only a scratch, after which the dozer continued to roll over onto its top in the creek bottom.
The report did not include information about how the dozer was eventually extracted, or what repercussions, if any, befell the operator and the contractor.

November 1 marked the 50th anniversary of the day that 12 wildland firefighters perished on the Loop Fire. The El Cariso Hotshots were constructing fireline on the Angeles National Forest in southern California in 1966 when the fire blew up below them.
Yesterday hundreds of people attended a commemoration event held at El Cariso Regional Park in Sylmar, California. Having been on the crew four years after the disaster, from 1970 through 1972, I wish I could have been there. But Stuart Palley, an accomplished fire photographer, was, and he took these excellent photos and wrote the captions. Thanks Stuart for allowing us to use them here.
In 1932 Robinson Jeffers published a book of poetry titled Thurso’s Landing and Other Poems that was set in the central coast region of California. One poem in particular was written about a vegetation fire — possibly the Matilija Fire that burned 220,000 acres that year which is the fifth largest recorded fire in the state.
The deer were bounding like blown leaves
Under the smoke in front the roaring wave of the brush-fire;
I thought of the smaller lives that were caught.
Beauty is not always lovely; the fire was beautiful, the terror
Of the deer was beautiful; and when I returned
Down the back slopes after the fire had gone by, an eagle
Was perched on the jag of a burnt pine,
Insolent and gorged, cloaked in the folded storms of his shoulders
He had come from far off for the good hunting
With fire for his beater to drive the game; the sky was merciless
Blue, and the hills merciless black,
The sombre-feathered great bird sleepily merciless between them.
I thought, painfully, but the whole mind,
The destruction that brings an eagle from heaven is better than mercy.
I have to admit — my six-second attention span rarely allows me to concentrate on the content of a poem that is more than a few lines long, but a couple of phrases stood out; Beauty is not always lovely, and in describing an eagle, Insolent and gorged, cloaked in the folded storms of his shoulders.
Mr. Jeffers led a very interesting life, coining the word inhumanism, the belief that mankind is too self-centered and too indifferent to the “astonishing beauty of things.” He briefly studied forestry at the University of Washington, had a scandalous affair with a married woman that was reported in the LA Times, and published many highly acclaimed books. But after writing about his staunch opposition to the United States’ entering World War II critics turned against him.
