Smokejumpers are specially trained wildland firefighters who provide an initial attack response on remote wildfires. They are inserted at the site of the fire by parachute. This allows firefighters to access remote fires in their early stages without needing to hike long distances carrying equipment and supplies. Traditional terrestrial crews can use only what they can carry and often require hours and days to reach fire on foot. The benefits of smokejumping include the speed at which firefighters can reach a burn site, the broad range of fires a single crew can reach by aircraft, and the larger equipment payloads that can be delivered to a fire compared to pedestrian crews.
This glossary of wildfire terms is a list of definitions of terms and concepts relevant to wildfires and wildland firefighting. Except where noted, terms have largely been sourced from a 1998 Fireline Handbook transcribed for a Conflict 21 counter-terrorism studies website by the Air National Guard.
In the United States, a Shot Crew, officially known as an Interagency Hotshot Crew (IHC), is a team of 20-22 elite wildland firefighters that mainly respond to large, high-priority fires across the country and abroad. They are assigned to work the most challenging parts of the fire and are considered strategic and tactical wildland fire experts. Hotshots are a national resource and their deployment is controlled at the national level. Hotshot crews are considered the most highly trained, skilled and experienced wildland firefighters, along with smokejumpers. They are qualified to provide leadership for initial-attack and extended-attack on wildland fires. Hotshots are trained and equipped to work in remote areas for extended periods of time with minimal logistical support. They are organized by agencies such as the United States Forest Service, National Park Service, Bureau of Indian Affairs, Bureau of Land Management, and state/county agencies; the National Interagency Fire Center coordinates hotshot crews on the federal level.
Wildfire suppression is a range of firefighting tactics used to suppress wildfires. Firefighting efforts depend on many factors such as the available fuel, the local atmospheric conditions, the features of the terrain, and the size of the wildfire. Because of this wildfire suppression in wild land areas usually requires different techniques, equipment, and training from the more familiar structure fire fighting found in populated areas. Working in conjunction with specially designed aerial firefighting aircraft, fire engines, tools, firefighting foams, fire retardants, and using various firefighting techniques, wildfire-trained crews work to suppress flames, construct fire lines, and extinguish flames and areas of heat in order to protect resources and natural wilderness. Wildfire suppression also addresses the issues of the wildland–urban interface, where populated areas border with wild land areas.
The Rattlesnake Fire was a wildfire started by an arsonist on July 9, 1953, in Powder House Canyon on the Mendocino National Forest in northern California. The wildfire killed one Forest Service employee and 14 volunteer firefighters from the New Tribes Mission, and burned over 1,300 acres (530 ha) before it was controlled on July 11, 1953. It became and remains to this day a well-known firefighting textbook case on fatal wildland fires.
Helitack crews are teams of wildland firefighters who are transported by helicopter to wildfires. Helicopters provide rapid transport, enabling helitack crews to quickly respond and assess a wildfire situation. Helitack crews may land near a wildfire or, if equipped and trained, rappel from a hovering helicopter. Once on the ground, crews build firelines using hand tools, chainsaws, and other firefighting tools. They often remain overnight in remote locations. After they have completed their assignment, crew members may pack up to 120 pounds of equipment over difficult terrain to reach a pick-up point. Rappellers often prepare helispots that provide better access to a fire. Helicopter crew members may also perform other duties such as tree falling, firing operations, and managing helibases.
The South Canyon Fire was a 1994 wildfire that took the lives of 14 wildland firefighters on Storm King Mountain, near Glenwood Springs, Colorado, on July 6, 1994. It is often also referred to as the "Storm King" fire.
Wildfire suppression in the United States has had a long and varied history. For most of the 20th century, any form of wildland fire, whether it was naturally caused or otherwise, was quickly suppressed for fear of uncontrollable and destructive conflagrations such as the Peshtigo Fire in 1871 and the Great Fire of 1910. In the 1960s, policies governing wildfire suppression changed due to ecological studies that recognized fire as a natural process necessary for new growth. Today, policies advocating complete fire suppression have been exchanged for those who encourage wildland fire use, or the allowing of fire to act as a tool, such as the case with controlled burns.
The 2009 California wildfires were a series of 9,159 wildfires that were active in the US state of California, during the year 2009. The fires burned more than 422,147 acres of land from early February through late November, due to Red Flag conditions, destroying hundreds of structures, injuring 134 people, and killing four. The wildfires also caused at least US$134.48 million in damage. Although the fires burned many different regions of California in August, the month was especially notable for several very large fires which burned in Southern California, despite being outside of the normal fire season for that region.
The Station Fire was the largest wildfire of the 2009 California wildfire season, as well as the largest wildfire in the history of Los Angeles County, that burned in the Angeles National Forest, igniting on August 26, 2009, near the U.S. Forest Service Angeles Station 11 ranger station on the Angeles Crest Highway. It threatened 12,000 structures in the National Forest and the nearby communities of La Cañada Flintridge, Pasadena, Glendale, Acton, La Crescenta, Juniper Hills, Littlerock and Altadena, as well as the Sunland and Tujunga neighborhoods of the City of Los Angeles. Many of these areas faced mandatory evacuations as the flames drew near, but as of September 6, all evacuation orders were lifted. The Station Fire burned on the slopes of Mount Wilson, threatening numerous television, radio and cellular telephone antennas on the summit, as well as the Mount Wilson Observatory, which includes several historically significant telescopes and multimillion-dollar astronomical facilities operated by UCLA, USC, UC Berkeley and Georgia State University.
The Thirtymile Fire was first reported on July 9, 2001 in the Okanogan National Forest, approximately 30 miles (48 km) north of Winthrop, Washington, United States. The wildfire had been caused by an unattended campfire that spread rapidly in the hot and dry weather in the Pacific Northwest. Four firefighters were killed when the fire cut off their only escape route out of the narrow canyon.
The Waldo Canyon fire was a forest fire that started approximately 4 miles (6.4 km) northwest of Colorado Springs, Colorado on June 23, 2012, and was declared 100 percent contained on July 10, 2012, after no smoke plumes were visible on a small portion of the containment line on Blodgett Peak. The fire was active in the Pike National Forest and adjoining areas, covering a total of 18,247 acres. The fire had caused the evacuation of over 32,000 residents of Colorado Springs, Manitou Springs and Woodland Park, several small mountain communities along the southwestern side of U.S. Highway 24, and partial evacuation of the United States Air Force Academy. There were 346 homes destroyed by the fire. U.S. Highway 24, a major east–west road, was closed in both directions. The Waldo Canyon Fire resulted in insurance claims totaling more than US $453.7 million. It was the most destructive fire in Colorado state history, as measured by the number of homes destroyed, until the Black Forest Fire surpassed it almost a year later when it consumed 486 homes and damaged 28 others.
On August 18, 1937, a lightning strike started the Blackwater Fire in Shoshone National Forest, approximately 35 miles (56 km) west of Cody, Wyoming, United States. Fifteen firefighters were killed by the forest fire when a dry weather front caused the winds to suddenly increase and change direction. The fire quickly spread into dense forest, creating spot fires that trapped some of the firefighters in a firestorm. Nine firefighters died during the fire and six more died shortly thereafter from severe burns and respiratory complications. Another 38 firefighters were injured. The fire killed more professional wildland firefighters in the U.S. than any other in the 103 years between the Great Fire of 1910 and the Yarnell Hill Fire in 2013.
The Yarnell Hill Fire was a wildfire near Yarnell, Arizona, ignited by dry lightning on June 28, 2013. On June 30, it overran and killed 19 members of the Granite Mountain Hotshots. Just one of the hotshots on the crew survived—he was posted as a lookout on the fire and was not with the others when the fire overtook them. The Yarnell Hill Fire was one of the deadliest U.S. wildfires since the 1991 Oakland Hills fire, which killed 25 people, and the deadliest wildland fire for U.S. firefighters since the 1933 Griffith Park fire, which killed 29 "impromptu" civilian firefighters drafted on short notice to help battle that Los Angeles area fire.
The October 2007 California wildfires, also known as the Fall 2007 California firestorm, were a series of about thirty wildfires that began igniting across Southern California on October 20. At least 1,500 homes were destroyed and approximately 972,147 acres of land was burned from Santa Barbara County to the U.S.–Mexico border, surpassing the October 2003 California wildfires in scope, which were estimated to have burned 800,000 acres (3,200 km2). The wildfires killed a total of 14 people, with nine of them dying directly from the fires; 160 others were injured, including at least 124 firefighters. At their height, the raging fires were visible from space. These fires included the vast majority of the largest and deadliest wildfires of the 2007 California wildfire season. The only wildfire in 2007 that surpassed any of the individual October 2007 fires in size was the Zaca Fire.
The Holy Fire was a wildfire that burned in the Cleveland National Forest in Orange and Riverside Counties, California. The wildfire started on August 6, 2018 at around 1:15 PM PDT, in the vicinity of Trabuco Canyon. A suspected arsonist was booked into the Orange County jail in Santa Ana, California but found not guilty in 2023. The blaze burned 23,136 acres (94 km2) and destroyed 18 buildings, before it was fully contained on September 13, 2018. While the fire was actively spreading in early and mid-August, residents of the nearby cities of Corona, Temescal Valley, and Lake Elsinore were placed under evacuation orders.
The El Dorado Fire was a wildfire that burned 22,744 acres in San Bernardino and Riverside counties of California from September to November 2020. It was ignited on September 5 by a pyrotechnic device at a gender reveal party in El Dorado Ranch Park; it quickly spread to the San Gorgonio Wilderness Area of the San Bernardino National Forest. Burning over a 71-day period, the fire destroyed 20 structures and resulted in one firefighter fatality, for which the couple hosting the party were charged with involuntary manslaughter.
The Mosquito Fire was California's largest wildfire of 2022, burning in the American River watershed in Placer and El Dorado counties in Northern California. The fire began on September 6 amid a state-wide heat wave and went on to burn 76,788 acres, primarily in the Tahoe and Eldorado National Forests, while also destroying 78 structures in the rural communities of Michigan Bluff, Foresthill, and Volcanoville. Authorities declared the fire fully contained on October 22 following several storms. The fire suppression effort cost more than $180 million, and at its peak involved more than 3,700 firefighters. The precise cause of the fire is not known, but the potential role of Pacific Gas & Electric Company (PG&E) equipment is the subject of multiple civil lawsuits and a Forest Service investigation. The Mosquito Fire was one of 7,477 total wildfires in California in 2022, which burned a combined 331,358 acres (134,096 ha).
The Kinneloa Fire was a destructive wildfire in October 1993 in Los Angeles County, California. The fire burned 196 structures in the San Gabriel Mountains foothill communities of Altadena, Kinneloa Mesa, and Sierra Madre, becoming the 12th most destructive wildfire in recorded California history at the time and to this day one of the most destructive wildfires in Los Angeles County history. The fire resulted in one fatality and a multitude of minor injuries: one person died of pneumonia complicated by smoke inhalation, and two indirect deaths resulted from debris flows in the burn area more than four months later.
The Flathead Hotshots are a U.S. Forest Service interagency hotshot crew located in the Hungry Horse Ranger District of the Flathead National Forest in Hungry Horse, Montana.
