At approximately 12:06 the seventh spot escaped initial control efforts and began to move east towards the highway. This forced the personnel on the fire to use M-33 as the next logical control feature. The Burn Boss requested another Sheriff’s patrol at 1208 for M-33 due to continued heavy smoke. At approximately the same time the escaped fire was burning downslope towards M-33 on the west side of the highway. The tractor plow had constructed a line along the north side of the spot fire and connected it to M-33. However, the line did not hold.

On May 5, 1980 employees of the Mio Ranger District, Huron-Manistee National Forests ignited the Crane Lake Prescribed Fire. They intended to burn a 28 acre unit, along side State Highway M-33. The goal was to reduce the slash fuel load to prepare the site for planting jack pine to create habitat for the endangered Kirtland’s Warbler. Fuels on the site included grass, shrubs and scattered discontinuous logging slash. Resources on hand were 11 personnel, 1 John Deere 450 tractor plow, a 125 gallon engine, and a 6x6 1000 gallon engine.

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.

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.

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.

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.

As the intensive prep work near the corner house was completed a firing operation began. By 1300 Perryville had continued to improve line and made it approximately one-third of the way down Walk Moore Canyon where they ran out of drinking water. The crew boss and one crewmember walked to the Control Road and sent water back to the crew via ATV.

At 0230 the Perryville crew met with Division Supervisor Dale Ashby at the Control Road and Walk Moore Canyon Junction. The crew's assignment was to anchor at the Control Road and construct line up the jeep trail. The crew completed the line on the jeep trail and continued up the power line right-of-way into the Bonita Creek Estates Subdivision.
