Location of the Kinneloa Fire in Southern California

The Kinneloa Fire was a destructive wildfire in Los Angeles County, Southern California in October of 1993. The fire destroyed 196 buildings in the communities of Altadena, Kinneloa Mesa, and Sierra Madre in the foothills of the San Gabriel Mountains, becoming at the time the twelfth-most destructive wildfire in California's history and one of the most destructive wildfires ever in Los Angeles County. The fire caused a multitude of minor injuries and one fatality; an elderly man died of pneumonia complicated by smoke inhalation. A father and son were killed by a debris flow in the burn area more than four months later.

The Kinneloa Fire began as an escaped campfire on October 27 and was driven by a combination of extremely dry and flammable vegetation, strong Santa Ana winds, and rugged topography. Nearly all of the structural losses occurred on the first day, and more favorable weather—along with the efforts of over 2,000 firefighters—kept the fire within the mountainous backcountry of the Angeles National Forest until it was declared fully contained on November 1.

The Kinneloa Fire was one of a rash of wildfires that broke out across Southern California in late October 1993, most of them driven by the same episode of Santa Ana winds. These included the Laguna Fire in Orange County, the Green Meadow Fire in Ventura County, the Ortega Fire in Riverside County, and several others.[1][2]

Background

In the autumn of 1993, California had experienced a full six years of severe drought between 1986 and 1992, which contributed to a build-up of dead and dry brush in Southern California. This was followed by a wet winter in 1992–1993, which allowed new grass and brush to grow in the spring and then dry out once more over the summer and fall.[3] Southern California mountain vegetation is rife with species like chamise and manzanita, which comprise chaparral: one of the most fire-prone plant communities, containing flammable oils and resins and slow to rot or decay.[4]

This map of relative humidity at 12Z (4:00 am. PDT, when the fire began) on Oct 27 shows widespread low RH levels across Southern California.

On October 27, 1993, the National Park Service morning report read:

Red flag warnings are in effect for low humidity and strong north to east winds in much of central and southern California. A red flag watch also remains in effect for low humidity and gusty winds in northern inland valleys. Initial attack and possible large fires are expected to continue in California due to these conditions.[5]

The red flag warnings in Southern California were due to forecast Santa Ana winds. Santa Ana winds are a regular meteorological phenomenon in the autumn, generated when a high-pressure system builds in the Great Basin. The system pushes air clockwise, downwards from the northeast into the Los Angeles Basin, heating and drying it as it descends. The airmass also accelerates as it is forced through gaps in the mountains or over ridges, creating strong downslope winds.[6]

Studies of historical charcoal records indicate that large wildfires driven by Santa Ana winds have long been a natural part of chaparral landscapes in Southern California, even accounting for human-driven changes in fire suppression and fire ignitions over time.[7][8]

In addition to the forecast winds of 15–25 miles per hour (24–40 km/h), temperatures on October 27 were forecast to reach around 90 °F (32 °C). The overall resulting weather pattern concerned regional fire officials,[9] and the Angeles National Forest was closed to recreational usage between October 27 and 29.[10]

Progression

October 27

The Kinneloa Fire began before dawn on the morning of October 27, 1993. It originated as an escaped campfire, built by a homeless man suffering from undiagnosed schizophrenia on the slopes of the San Gabriel Mountains above northeastern Altadena. Andres Huang, 35, was sleeping in a small grove of pine trees adjacent to the Mount Wilson Toll Road (a dirt road typically used by hikers), roughly halfway between Eaton Canyon and Henninger Flats, when he woke up cold and built a small fire from pine needles and twigs to warm himself. Huang's fire escaped the circle of stones he had lit it in almost immediately. He attempted to smother the fire, but it had grown too large, and Huang fled.[11]

Los Angeles County Fire Department (LAFCD) Station 66, located at the base of Eaton Canyon, received the first call about the fire at 3:48 a.m. PDT. It quickly became clear that the incident, quickly dispatched as the Kinneloa Fire, had the potential to become a major incident. The LACFD requested the assistance of the Pasadena Fire Department within seven minutes of the initial call,[12] and shortly thereafter both departments entered unified command with the Forest Service. County firefighters arrived on scene by 3:56 a.m., reporting a two-acre (0.81 ha) "creeping" fire in steep terrain.[13]: 50  The Forest Service requested two helicopters for dropping water at first light.[11] By 4:45 a.m., the fire was still only three acres (1.2 ha).

The fire's behavior quickly changed as the sun rose and the Santa Ana winds arrived. Wind gusts of up to 40–60 miles per hour (64–97 km/h) began to spread the fire rapidly.[14] The incident command requested air tankers. Around 5:30 a.m., the fire trapped and overran 15 firefighters on the toll road, though the deployment of fire shelters prevented any serious injuries.[13]: 50  The fire began to move down through Eaton Canyon, and evacuations in nearby neighborhoods began.[11][13]: 50  At 5:45 a.m., the Incident Command Post near Midwick Drive and Altadena Drive burned over, and had to be re-established at Eaton Canyon Nature Center. By 6:00 a.m., incident commanders were ordering engine strike teams (a strike team consists of five engines) for structure protection. The fire reached the arroyo at the bottom outlet of Eaton Canyon between 6:00 a.m. and 6:30 a.m..[11][14] When it reached the arroyo, the fire split into two main flanks: one moved west towards Altadena, and one moved south towards Canyon Close Road.[11] At around 6:10 a.m., the incident command post's new location at the Nature Center burned over again. Evacuations began for approximately 2,000 residents between Sierra Madre to the east and Altadena to the west.[13]: 51  Saint Luke's Medical Center was included, resulting in the evacuation of at least 125 patients as well as at least 50 residents from nearby nursing homes. Temporary shelters were established at several local public schools, including Eliot Middle School, Wilson Middle School, and John Muir High School.[15]

The incident command post relocated to Victory Park.[14] Even as Los Angeles County Fire Department helicopters arrived on scene to begin dropping water, structures in Altadena began to burn at 6:45 a.m.[13]: 51  At the same time, the southern flank of the fire moved east, driven by the winds towards Kinneloa Mesa. The unincorporated community of Kinneloa Mesa consists of residential neighborhoods of single-family homes, sitting atop a broad mesa that emerges where the San Gabriel Mountains' foothills flatten out, carved by multiple steep canyons that drop down to Eaton Canyon on the west side and the neighborhoods of Pasadena Glen and Sierra Madre on the east side. The neighborhood contains many narrow streets (some only 18 feet (5.5 m) wide) and multiple dead ends, making it a dangerous environment for firefighters—the Pasadena Star-News went so far as to call those streets "deathtraps". According to the Star-News, the chimney-like effect of the strong winds and pre-heating blew the fire up the canyon sides and into Kinneloa Mesa in just 90 seconds.[14] Many homes, particularly those on the edges of the canyons, quickly caught fire.[14][13]: 51  By 7:15 a.m., the fire was 300 acres (120 ha), and by 8:15 a.m., more than 600 acres (240 ha).[13]: 51  As the fire behavior increased, it burned as much as 300 acres (120 ha) every 10 minutes.[14]

At 8:00 a.m., thick smoke shorted out power lines in Kinneloa Mesa. This cut power to one of the water reservoirs operated by the Kinneloa Irrigation District, the local water company. Because Kinneloa Mesa rose above the surrounding terrain, keeping the reservoirs full required pumping water from wells further downhill. Without the power lines, and with no backup generators installed (for lack of funds), the District could not long maintain water pressure for long in the Kinneloa neighborhoods.[16][14] Helicopters continued to drop water, refilling near Verdugo Hills Hospital in La Cañada Flintridge,[14] but fixed-wing air tankers were unable to operate in the high winds after 9:30 a.m.[13] As the day went on, other wildfires in Southern California grew into major incidents with resource demands of their own: 25 engine companies that had come from Orange County left for the Laguna Fire, under a mutual aid clause that allowed them to return in case of emergency.[14][Note 1] The Kinneloa Irrigation District water tanks were empty by 11:45 a.m., leaving firefighters unable to hook up to fire hydrants in the upper parts of Kinneloa Mesa.[16][14] By noon, the fire was approximately 4,000 acres (1,600 ha).[2] Structures continued to burn throughout the afternoon along the fire's 8-mile perimeter, even as multiple homeowners remained to defend their properties with what they had on hand.[11][14] The neighborhood of Pasadena Glen, below Kinneloa Mesa's eastern flank, went largely undefended; 27 homes burned there.[14]

In the afternoon, the Santa Ana winds subsided. Firefighters took advantage of the conditions, and by 5:00 p.m., most of the spot fires in Kinneloa Mesa were extinguished. Near sunset, firefighters made two simultaneous stands: 39 engines arrayed at Rubio Canyon stopped the fire there, though several homes were lost on Zane Grey Terrace, and more firefighters grouped at Park Vista Drive above Sierra Madre.[14] After two hours of structure defense and setting backfires, they were able to prevent the fire from progressing into the neighborhoods to their south.[12]

October 28–31

The National Weather Service forecast a return to Santa Ana winds on October 30–31: weaker than the October 27–28 episode, but still concerning to firefighters as multiple fires, including the Kinneloa Fire, remained uncontained. A Forest Service officer fretted: "This area burns very aggressively with no winds at all. I'm very worried," in advance of the winds.[17] However, to the gratitude of fire officials, the predicted gusts of 40 miles per hour (64 km/h) did not materialize.[18]

The fire was 50 percent contained by the night of October 29, as firefighters shored up multiple flanks: to the west, above Altadena, they set a 200-acre (81 ha) backfire to strengthen control lines along Chaney Trail, which stopped the fire from continuing into Millard Canyon and threatening Jet Propulsion Laboratory and The Meadows subdivision. To the east, they used dozers to widen a large firebreak on the ridge between Little Santa Anita Canyon, with the most fire activity, and Big Santa Anita Canyon, which contained dozens of summer cabins and from which the fire might have threatened Sierra Madre. These efforts were supported by aircraft dropping water and fire retardant, including Boeing CH-47 Chinook helicopters—their use a first for Los Angeles County—and Lockheed C-130 Hercules fixed-wing aircraft.[19]

By October 31, the fire was 95 percent contained,[20] and on November 1, the Kinneloa Fire was declared 100 percent contained.[21] At peak staffing, at least 2,100 firefighters had worked to contain it.[22]

Casualties

The Kinneloa Fire caused at least 38 minor injuries, at least 29 of them to firefighters.[23] Most of the firefighter injuries were among crews cutting firebreaks by hand on the hillsides, though none of them were serious.[24] The only direct death from the fire was Alfred Wagner, 98, who died on November 9 of pneumonia. The Sheriff's Department said the death was caused by complications from smoke inhalation that occurred on October 27, when Wagner attempted to defend his home near Eaton Canyon with a garden hose before being made to evacuate by his caretaker.[25] The Los Angeles County District Attorney's office considered bringing involuntary manslaughter charges against Huang for Wagner's death but ultimately declined to do so.[26]

Two fatalities occurred when, after rains the following March, a father and son on a hike were killed by debris flows in a narrow canyon in the burn area above Sierra Madre. John Henderson, 33, and Matthew Henderson, 9, were on an outing in Bailey Canyon when a presumed cloudburst over the scorched burn area led to a sudden and violent flash flood. Their bodies were swept into the Bailey Canyon Wilderness Park debris basin, and an exhaustive day-and-night excavation using bulldozers, backhoes, and dump trucks took 15 days to locate their remains under 18 feet (5.5 m) of mud.[27] Arguing that the Kinneloa Fire was a proximate cause of the debris flow, Los Angeles County officials applied for aid from the Federal Emergency Management Agency (FEMA) to fund the search.[28]

Damage

The fire ultimately burned 196 structures.[29] One hundred and twenty-one of those structures were houses,[30][31] and they included the Pasadena home of football coach Johnnie Lynn and the former residence of naturalist John Burroughs.[11][32] An additional 40 homes were damaged.[30][31] Dozens of vehicles were also destroyed.[23] The fire impinged on, but did not burn, the ranch and art colony of bohemian artist Jirayr Zorthian in Altadena.[33] Many houses that burned in the Kinneloa Fire were highlighted by firefighters as being particularly susceptible to destruction because of their flammable wood shingle roofs.[34] Cal Fire officials and others called the Kinneloa Fire an example of the "fire of the future", referring to wildfires burning near inhabited areas that could not be countered with common indirect firefighting tactics.[24]

Multiple California politicians, including Senator Dianne Feinstein and Governor of California Pete Wilson, came to survey the damage in Altadena and Kinneloa Mesa.[17] Wilson declared a state of emergency in Los Angeles County and compared the neighborhoods devastated by the Kinneloa Fire to the aftermath of the Oakland fire.[35] In response to the wildfire outbreak, on October 28 President Bill Clinton in a speech declared five California counties disaster areas (including Los Angeles County) and promised federal assistance. He sent Federal Emergency Management Agency Director James Lee Witt, Secretary of the Interior Bruce Babbitt, and Secretary of Agriculture Mike Espy to Southern California to help coordinate emergency management and recovery efforts.[36] The Kinneloa Fire cost approximately $65.5 million, with $58.5 million sustained in losses,[37] plus nearly $7 million spent on the suppression of the fire.[38]

At the time, it was the twelfth most destructive wildfire in recorded California history, and though it has since fallen well out of the top 20 statewide, it remains one of the most destructive wildfires in the history of Los Angeles County.[29][39][40]

Post-fire landscape impacts

After the fire, more than 63 miles (101 km) of recreational trails and roads in Angeles National Forest were closed and not reopened until spring.[41] Less than a week after the fire, county workers began spreading a mixture of seeds over 3,900 acres (1,600 ha) of the burn area. The seed mix included California poppies, deer weed, 'Cucamonga' California brome, rose clover, and non-native rye grass (which environmentalists opposed).[42] The process was deemed necessary because of the risk of floods and debris flows: according to a member of the government rehabilitation team for the Kinneloa Fire burn area, approximately 80 percent of the footprint burned at a high severity, leaving no vegetation to help hold the steep hillsides together.[20]

Rainfall in November, shortly after the fire, caused mudslides in the fire scars across Southern California. Fire departments distributed tens of thousands of sandbags in the San Gabriel Valley.[43] During several different storms in the spring after the fire, the National Weather Service issued flash flood warnings for parts of Altadena and Sierra Madre at risk from debris flows from the burn area. Many residents evacuated, including most of the residents of Pasadena Glen, a canyon neighborhood immediately east of Kinneloa Mesa.[44][45] Around 2,000 cubic yards of material collected in the Kinneloa debris retention basin, one of several, over the following winter.[46]

Sheriff's deputies found and arrested Huang at 6:45 a.m., more than three hours after the fire had started, and he was arraigned on October 29.[47] He was injured from running down the hillside through brush, disoriented, and severely dehydrated. He also spoke no English, complicating efforts by police to understand his story.[48]

News reports often referred to Huang as a homeless man or transient hiker, but after talking with interpreters and probation officers, Huang's story emerged. He was born in China and had been a successful local official there, but fled to Peru—leaving behind a wife and daughter—when he became disillusioned by Chinese Communist Party crackdowns following the 1989 Tiananmen Square protests and massacre. He worked for an electronics company in Lima until he volunteered to establish a U.S. branch of the company, arriving in Los Angeles with a worker's visa in 1993. While staying in a hotel, Huang fell and suffered a major head injury, losing consciousness. Over the following weeks, he began experiencing severe paranoia and recurring blackouts, resulting in the loss of his job. Huang could not even recall how he had ended up on the mountainside where he started the campfire. Metropolitan State Hospital psychiatrists later diagnosed Huang with multiple conditions, including major depression, schizophrenia, and brain lesions.[48]

On November 29, Huang pled no contest to the misdemeanor charge of starting an illegal open fire. He remained in a mental hospital until his sentencing in December.[49] On December 21, Huang was released from jail and sentenced to three years of probation, under the condition that he receive treatment at a residential treatment center.[48]
