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.

On June 25, 1990, a lightning strike sparked a fire beneath the Mogollon Rim about 10 miles northeast of Payson. Conditions were such that the fire burned quickly and within a matter of hours the Dude Fire had become extremely active. The fire was reported at 1315. Initial attack resources arrived at 1400 to find a very active10-acre fire. An hour later over 360 firefighters including engines, dozers, handcrews, aviation resources, and a Type II Incident Management Team had been ordered. The Type II IMT was on site and assumed command of the fire by 1800.

At this point, additional resources have been ordered through the dispatch center. An airtanker is also requested for assistance with the slopover. At this point, the Burn Boss decides to convert the prescribed fire to a wildland fire, which then becomes the Cerro Grande Fire. The Burn Boss then assumes responsibility for the fire as the Incident Commander and additional resources are ordered. Efforts then focus on suppressing the wildfire.
