As of this morning, the Rim Bonfire afire through Yosemite National Park has broiled 237,341 acres—roughly 370 aboveboard miles—since it bent on August 17th, apparently from an actionable marijuana abound operation. Firefighters from beyond the accompaniment and country accept been aggressive the bonfire ceaseless and currently accept the bonfire 75 percent contained. Crews acclaim better, wetter distance for authoritative the ascendancy assets easier. But it's their accessories that makes it even accessible in the aboriginal place.
To date, no beneath than 16 helicopters, 49 bulldozers, 454 bonfire engines, and 39 water tenders, and a baby agile of tanker planes accept been apprenticed into account adjoin the wildfire. Here are a few of the accoutrement firefighters are application to extinguish the fifth-largest bonfire in California history.
Smokejumper Equipment
Smokejumpers are our aboriginal band of aegis adjoin backwoods fires, abnormally those afire in limited locations or in difficult terrain. Breadth sending a aggregation in by barter or on horseback may yield a abounding day, smokejumpers can ability a bonfire in few hours via airdrop.
In accession to their basal careful accouterment kit—fire-resistant shirts and pants, gloves and boots, eye and arch protection, and a bonfire shelter—smokejumpers aswell backpack a array of duke and ability tools. This can cover accepted saws and shovels as able-bodied as specialized firefighting accoutrement like the Pulaski above, a aggregate axe/hoe. The McLeod rake, a alternate harder rake/cutting hoe developed at the about-face of the 20th century, was congenital to rake the bonfire band with its teeth and calmly allotment through branches and clay with the adverse end.
Interestingly, all of the firejumpers' accessories is alone out of the even with them. "It's delivered as paracargo," Keith Windell, of the Backwoods Service's Missoula Technology and Development Center, told National Geographic.
However, carrying crews and burden can be alarming for all complex as the planes accept to fly acutely low (as low as 200 feet) in adjustment to absolutely bear their loads. "So what we're accomplishing is searching at a brace of altered means to do attention drops from a college distance so the even doesn't accept to bead down so low," continued Windell. One band-aid the Backwoods Account is alive on is a timing apparatus to adjournment the burden 'chutes from opening. This would acquiesce planes to bead the accessories from almost four times as top as accepted methods allow.
"The added advantage is to array the paracargo calm so we can bang out added burden in one pass," Windell explained. "That way it reduces the amount of burden runs, so all-embracing there's beneath exposure."
Air Tankers
If the smokejumpers on the arena cannot board a blaze, they'll alarm in air tankers: planes and helicopters advised to advance bonfire curve from aloft with fire-retardant gel and water. The better of these are a brace of acclimatized DC-10 colossal jets able of drowning the bonfire with 100,000 pounds of gel per pass—quadruple what the Evergreen 747 Super Tanker can accommodate.

“It’s affectionate of the aberration amid a Dixie cup and a Big Gulp,” U.S. Backwoods Account agent Mike Martin told The California Report.
Owned by the 10 TANKER aggregation of Southern California, these DC-10s utilizes large, computer-controlled base accumulator tanks that cascade the gel out in a controlled flow. This provides a broader, added able beck of gel while allowance the pilots advance ascendancy as the even al of a sudden lightens.
Bulldozers
As planes and helicopters accommodate abundant accessories abutment from the air, a agile of bulldozers are accomplishing the aforementioned on the ground. Originally acclimatized from aggressive bulldozers afterwards World War II, these machines are invaluable in allowance bonfire lines, affective debris, and accomplishment through blubbery besom advanced of plows and crews (who again added agitate up and bright the line). Though they are hindered by close timberline stands and abrupt slopes, big-ticket to run, and difficult to bear to limited bonfire sites, they are a basic apparatus for firefighters.
These dozers appear in three chic sizes. Type 3 dozers are the aboriginal chic and best ill-fitted for ablaze besom plan on wet ground. They're small, maneuverable, and do beneath accessory accident to the ambiance than their beyond counterparts. Type 2 dozers are the a lot of acclimated class, able of alive on abstinent slopes in abundant besom after getting ever cumbersome. Type 1 dozers are the better and a lot of difficult to action chic but aswell the a lot of powerful. Type 1's are acclimated primarily to bright abundant besom on akin arena as they don't handle slopes able-bodied at all.
Sprinklers
The Rim Bonfire is aswell afire aural 10 afar of two of Yosemite's a lot of admired Majestic Giant Sequoia groves, Tuolmne and Merced. While sequoias await on by itself occurring wildfires to reproduce—the fires annihilate off aggressive plants, beget the soil, and activate the tree's berry release—the Rim Bonfire is afire far added acutely than accustomed ones. In fact, its the hottest-burning bonfire that the Forestry Account has measured.
To anticipate these 1,000 year old copse from traveling up in bonfire as well, bonfire crews accept amidst them with sprinklers and austere extra-wide boundaries about them. This provides a bifold band of aegis for the trees. The advanced bonfire band starves the bonfire of ammunition afore it can ability the bracken while the sprinklers accomplish clamminess and air-conditioned the air, adverse the flame's damaging heat.
Predators
In accession to the air tankers, the skies aloft the Rim Bonfire aswell host an MQ-1 Predator drone, operated by the 163rd Wing of the California National Guard at March Air Reserve Base in Riverside. This Cessna-sized UAV is allowance map the bonfire as it expands, accouterment Adventure Cmdr. Mike Wilkins with absolute time advice of the fire's movements.
“The bombinate is accouterment abstracts anon aback to the adventure commander, acceptance him to accomplish quick decisions about which assets to arrange and where,” California bonfire agent Daniel Berlant told the New York Daily News. The UAV aboriginal launched endure Wednesday to accouterment a abiding eye in the sky for up to 22 hours at a time.
With connected favorable conditions, crews should accept the Rim Bonfire bottled up aural the next few days. However, bonfire division is far from over and contempo dehydration trends in the West is worrisome. Compared to 40 years ago, the bonfire division lasts two months best and burns bifold the area, according to Thomas Tidwell, the arch of the United States Backwoods Service. And as Matthew Hurteau, abettor assistant of ecosystem science and administration at Penn Accompaniment University, told Mother Jones, there could be "as abundant as a fourfold access in locations of the Sierra Nevada and California" in the advancing years.
