Staff Ride to the Loop Fire

Staff Ride to the Loop Fire

On November 1, 1966, the El Cariso Hotshots, a U.S. Forest Service Interregional Wildland Firefighting crew, was trapped by flames as they worked on a steep hillside in Pacoima Canyon on the Angeles National Forest.

The crew was constructing fireline downhill into a chimney canyon and were within 200 feet of completing their assignment when a sudden shift of winds caused a spot fire directly below where they were working. Within seconds flames raced uphill, engulfing the firefighters in temperatures estimated to reach 2,500 degrees F. The fire flashed through the 2,200 foot-long chimney canyon in less than one minute, catching the crew while they attempted to reach their safety zones.

Ten members of the crew perished on the Loop Fire that day. Another two members succumbed from burn injuries in the following days. Most of the 19 members who survived were critically burned and remained hospitalized for some time.

Much of the knowledge gained about wildland fire has come through the high cost of firefighter lives. Lessons learned from the Loop Fire resulted in improved firefighting equipment, better fire behavior training, and the implementation of new firefighter safety protocols.

El Cariso Regional Park was established by the County of Los Angeles in honor of the hotshot crewmembers who were entrapped on the 1966 Loop Fire. This is a good location to begin a Staff Ride as it is easy to find, has good parking capacity, and provides an excellent perspective of the site from the monument.

The Loop Fire started at 0519 on November 1, 1966, from a faulty electrical line at the U.S. Army's Los Pinetos Nike Missile Site. This facility is approximately 1 mile north of Contractors Point. The fire burned downhill in a southwesterly direction under the influence of 40 to 60 mile per hour Santa Ana winds. Contractors Point was a key anchor point on this east flank of the fire, which was designated as Division A. Suppression efforts in Division A on the morning of November 1st were focused on protecting the missile facility and establishing a control line south from that facility toward Contractors Point.

See travel map above.

The entrance to the park is well marked. It will be a right turn if traveling north on Hubbard Street. The actual monument is all the way to the back of the parking area.

When viewing the San Gabriel Mountains from the park, one gains an appreciation for the extreme terrain over which the Loop Fire burned.  Contractors Point is the high point of the ridge just behind the tree on the left. The south point of the ridge is clearly visible in the center.

By mid day, the north flank of the fire had been contained along the Santa Clara Fuelbreak up to Contractors Point. With the exception of a few minor slopovers, the east flank of the fire was holding along the ridge to a point 40 chains south of Contractors Point (Stand 3). The Chilao Hotshot crew, two Los Angeles County crews, and several tankers (engines) were working a large slopover near Contractors Point. At 1200 the Dalton Hotshot crew on-scene at Contractors Point and were assigned by Division Boss William Westmoreland to build direct handline south from the Chilao crew along this east flank of the fire. At about 1300 the Del Rosa Hotshot Crew arrived, and Westmoreland directed them to work down the ridge ahead of the Dalton crew. At 1430 the El Cariso Hotshot crew arrived on-scene. Line Boss Hugh Masterson briefed El Cariso Superintendent Gordon King. Masterson's instructions were to "leap-frog the Del Rosa crew and to cold trail the fire edge if possible." He also mentioned that "the main ridge could be used as an alternate if impossible to follow the burned edge."

View looking toward the south point of the ridge from Contractors Point. Notice the break in the chamise brush field. This indicates the location of the fireline as it progressed south from Contractors Point during the late morning and early afternoon. The fireline was mostly built by dozers between the missile facility and Contractors Point. From Contractors Point south, handline was required.

This is shown as Point A in the investigation report photo referred to as Figure 3. El Cariso Superintendent King led his crew to a small bench below this south point of the ridge and held them there until he could determine if it was possible to cold trail the fire edge all the way down. King could see the Los Angeles County dozers and crews working the lower edge of the fire and believed he could tie in with them. At about 1445 Line Boss Masterson requested Division Boss Westmoreland to go down the east flank and make sure the crews were lined out. Westmoreland had a radio and several of the crews did not have radios, including the El Cariso Hotshots. By the time Westmoreland reached the tail end of the El Cariso crew, King had led the first units of his crew well down into the steep rocky chimney staying directly on the fire edge. As a result, King never had a radio exchange or face-to-face meeting with Westmoreland, who was his Division Boss.

Division Boss Westmoreland probably caught up with the tail end of the crew in about this location.

This is shown as Point E in the investigation report photo referred to as Figure 3. By about 15:30 the El Cariso Hotshots were fully committed, cold trailing their way down through the steep rocky chimney canyon with Superintendent King and the lead elements of the crew just starting to approach this point. Division Boss Westmoreland had followed them about halfway down and observed minimal fire activity, but he also stated that it was not a clean burn.

At about this same time, line construction by the Los Angeles County dozer and crews, that were working west along the bottom of the slope, was halted by a deep gully. This gully was adjacent to and just below the chimney canyon that the El Cariso crew was working down. There was no radio communication capability between the two groups, but they did have visual contact. Independently, both were trying to figure out how best to tie in the line. At this point, there was no more than 500 feet separating them.

Several individuals, who were working at the bottom of the fire, stated that the fire behavior was in a static situation with hot spots near the bottom of the gully and that there were favorable southeast winds. In addition, a helicopter was making water drops on the hotspots. According to these same observers, sometime between 1535 and 1545, the fire started to cross the bottom of the gully. Within the next 5 to 10 minutes the fire crossed the gully, made a run upslope to the bottom of the chimney, and then flashed very quickly up the length of the chimney. The steep rocky terrain made it very difficult for firefighters to move toward the previously burned area. Terrain conditions combined with the rapid fire spread resulted in all members of the El Cariso Hotshot crew being burned over as they worked from this stand location and up several hundred yards in the chimney above.

See the Investigation Report Figure 3 map, above, showing the fatality site with fire edge.

Rescue operations began immediately after the burnover. These efforts included having the helicopter hover over very rugged terrain while the fire was still active to pick up the survivors in the upper end of the chimney canyon.

That evening the Del Rosa and Dalton Hotshot crews went on to complete the handline down to the bottom of Pacoima Canyon using the ridge and indirect line location that was identified as the alternate strategy by Line Boss Masterson. The fire was contained that night at approximately 2,000 acres.

A Washington Office investigation and safety review was ordered following this accident. Several recommendations from the investigation and safety review caused significant changes in wildland firefighting equipment and procedures.

Pacoima Dam Road offers a good perspective of the entire working area around the fatality site, making it a good location to conduct the integration phase of the Staff Ride by having participants share their observations at the end of the day.
