During the late afternoon Sunday, rising temperatures and moderate winds contributed to more active burning on the Pioneer Fire, Boise National Forest officials said.
“This burning produced a sizable plume of smoke that was visible throughout the area, and gave the impression that the fire had spread farther than it did,” said spokeswoman Susan Blake.
Offocials say the warming trend will continue into the near future and could likely result in more active burning conditions. “As the fire spreads, it is anticipated that the smoke will continue to be seen throughout a large area including Boise, Cascade, Lowman and beyond," Blake stated.
Firefighters are making good progress in securing the southern and southeastern flanks of the fire in order to protect the Elk Creek drainage -- the main source of drinking water for the community of Idaho City, she added.
The 3,725 acre fire is currently 32 percent contained and has 768 personnel engaged in the suppression efforts.
Ten helicopters are conducting water drops. Additional resources include using 25 crews, ten of which are elite “hotshot” crews due to the rugged terrain where the fire is burning.
