Fire Behavior Associated with the 1994 South Canyon Fire on Storm King Mountain, Colorado
Fire Chronology (continued)
July 6, 1611 to 1614—Firefighters on West Flank Fireline Overrun
Main Ridge—As they retreated north along the ridge, the Main Ridge Group passed through active spot fires burning along the Main Ridge Fireline. Several of the firefighters later stated that fire was burning on both sides of the ridge (South Canyon Report). Some indication of the severity of the situation is indicated by the fact that they abandoned the chainsaw fuel containers on both sides of the trail. The main fire was producing a loud roar (South Canyon Report). Hotshot Scholz said that they felt that the fire was moving north at a pace equal to theirs (Scholz 1995). As they passed the Zero Point, the air contained burning embers and smoke. Hotshot Navarro, who was near the back of the group, said that when he neared the Zero Point, “The fire was only on my left or west” (South Canyon Report). At this time, Scholz and some of the other firefighters dropped off the east side of the Main Ridge and followed a trail that contoured along the side of the ridge toward H-2. Some firefighters recall hearing chainsaw fuel containers exploding behind them.
After leaving the Photo Point, Archuleta moved south toward the Zero Point to make sure that none of the firefighters in the Main Ridge Group turned down the West Flank Fireline. As the last of the Main Ridge Group firefighters passed him heading toward H-2, Archuleta also started toward H-2 (about 1612) (South Canyon Report). About 80 feet north of the Zero Point, Scholz looked back to the south along the ridge and saw the fire curling over the Main Ridge behind a firefighter running down the trail toward him (Scholz 1995). The fire burning up the slope behind the Spur Ridge had crested the Main Ridge 200 feet south of the Zero Point.
Main Ridge Near H-2—Robertson, Archuleta, and Ryerson remained on the Main Ridge. Ryerson, who was ahead of Archuleta and Robertson, stated that as she neared H-2 there was heat, intense smoke, and sparks everywhere, and the fire was close on the west side (South Canyon Report ; Good 1996; OSHA 1995). As they moved along the Main Ridge toward H-2, Robertson and Archuleta could feel heat behind and to their left. The remaining chainsaws and fuel containers were abandoned north of H-2. The firefighters were told to go down into the East Drainage.
Zero Point—Shortly after the last of the Main Ridge Group passed the Zero Point, BLM Firefighter Haugh, reached the top of the West Flank Fireline and continued a short distance over the ridge into the East Drainage. The heat was intense enough that Haugh received some first-degree burns (Husari 1996). Smokejumper Erickson, who followed shortly behind Haugh, received second-degree burns to his upper back, neck, and elbows (Hospital Report 1994).
West Flank Fireline—Based on our reconstruction of crew and fire movement and interviews with witnesses, we estimate that Jumpers Thrash and Roth stopped near the Tree about the time Haugh and then Erickson reached the Zero Point. The rest of the West Flank Fireline group following in a line behind them stopped. We estimate that after a short hesitation, Hotshot Blecha stepped around the group, and continued up the hill. Our timeline places Hipke about 45 seconds behind Erickson. We estimate that Blecha followed about 40 seconds (100 feet) behind Hipke.
H-2 and the East Drainage—Helicopter Pilot Good returned and hovered about 100 feet above and northeast of H-2 (between 1612 and 1613). He estimated his return time after dropping the water bucket at the subdivision to be 5 to 7 minutes (Good 1996; Hopf 1996; South Canyon Report). The pilot saw people running north along the Main Ridge and then moving off the ridge from a point south of H-2 down into the East Drainage. The pilot was unable to make radio contact with any of the firefighters. Winds were from the west and blowing harder than when the pilot had made the previous water drop on the Main Ridge. Grit and debris were blowing through the open cockpit doors. He could see fire burning along the top of the Main Ridge from H-1 to the intersection of the Spur Ridge and the Main Ridge. Flames were 150 to 200 feet high. Fire was burning 100 to 200 feet below (west) H-2. Fire had progressed north up the West Drainage and was spreading east toward the Saddle (Good 1996; OSHA 1995).
As the first members of the Main Ridge Group began descending into the East Drainage, Shepard, Blanco, and Helitack Crewmembers Tyler and Browning moved some red packs that had been left north of H-2 to a small depression nearer the helispot (approximately 1613). Shepard estimated that they only looked down for 20 seconds but were surprised when they looked up from moving the packs to find that the fire was nearly to H-2 (Shepard 1995). Smoke and burning embers were flying into the area and fusees with the gear at H-2 were igniting (Shepard 1995).
West Flank Fireline—Using all of the available information, our best estimate of the fire location between 1612 and 1613 is shown in figures 30 and 31. Fire was burning upcanyon and upslope as a continuous front that stretched from the Rocks to the junction of the Main Ridge and the Spur Ridge then down the Spur Ridge across the north end of the bench and partially up the slope toward the Photo Point and H-2.
The fire burned quickly up the hill. Prineville Hotshot Scott Blecha died 120 feet from the top of the fireline. Prineville Hotshot Crewmembers Kathi Beck, Tami Bickett, Levi Brinkley, Doug Dunbar, Terri Hagen, Bonnie Holtby, Rob Johnson, and Jon Kelso; and Smokejumpers Don Mackey, Roger Roth, and James Thrash were entrapped and died 200 to 280 feet below the Zero Point.
While Hipke hiked up the last section of the fireline he felt his arms and neck getting hot. He dropped his pulaski, which was later found 82 feet below the Zero Point, and tried to remove his fire shelter to use as a shield. Hot air and embers blew past him. He could feel his ears getting burned and it seemed to be getting hotter. His hardhat was on backwards, and the bill provided some protection to the back of his neck while he used his hands to shield his ears and face from the increasingly unbearable heat. He had difficulty getting the shelter out of its wrapper and dropped it 15 feet from the Zero Point when he tried to leap forward to escape the heat. As he jumped forward, hot air hit him forcibly from behind and he fell forward to the ground, yelling as he fell and catching his fall with his hands (estimated time 1614). After falling forward, he jumped back up and hiked across the top of the ridge, shielding his face and ears from the heat with his hands. Hipke, though burned on both sides, did not recall seeing fire as he hiked over the top of the Main Ridge. Figure 32 shows the location of the fire at this time. The shoulder straps on Hipke’s backpack had melted or fallen off, leaving the pack hanging by its belt strap and bumping against the backs of his thighs (Hipke 1994). Reaching the east edge of the Main Ridge he unsnapped the backpack belt strap, left the pack, and ran down the steep slope into the East Drainage. Hipke suffered third-degree burns over 10 percent of his body including his hands, arms and elbows, buttocks, thighs, calves, right shoulder, face, and back of his head. He received lesser burns on his left side (Hospital Report 1994). A few hundred feet down the slope Hipke met Haugh and Erickson who wrapped the burned portion of his arms and hands in a T-shirt and poured water over the makeshift bandage. Together they moved down the East Drainage. They were the first firefighters to reach the Interstate highway (Hipke 1995).
