A wildfire burning in heavy timber 50 miles east of Boise continued to spread even after pilots dropped more than 100,000 gallons of retardant on it. Boise State Public Radio reported that the fire burned through retardant lines on Sunday — the Trinity Ridge Fire grew from 200 acres on Saturday to 1,300 acres Sunday; it is now at 1,800 acres.
The fire gained ground in spite of the 46 runs made by four C-130 MAFFS tankers operating out of Boise. Three SEATs also worked the fire over the weekend.
Dave Olson, incident information officer, said the fire took off Friday in sub-alpine fir and lodgepole, both prone to torching and throwing embers. He said the fire is suspected to be human-caused; firefighters found a burned utility terrain vehicle at the fire’s source. Investigators are seeking the owner of the vehicle.
Additional fire crews have arrived, and a Type 2 team has assumed command.
Yesterday, the fire burned aggressively in the mostly sub-alpine fir and lodgepole pine, with considerable torching and spotting. NWCN.com reported that fire managers say current conditions are much drier then they’d originally thought. “It’s actually drier this year than it was in 2006 and 2007,” said Olson.
