The Pioneer Fire grew to more than 42,000 acres by Tuesday and crews lost a little bit of ground, with the containment dipping down to 28 percent, according to the Boise National Forest.
The estimated date for full containment has been pushed back to Sept. 15.
One yurt in the fire area has been destroyed and others are endangered. On Tuesday, fire managers posted a yurt update on InciWeb saying that the Whispering Pines/Gold Fork Yurt has been destroyed and the Stargaze Yurt is “still intact but slightly scorched,” with its outhouse destroyed. The condition of the Elk Horn and Rocky Ridge yurts is unknown, fire managers said.
The Forest Service says 1,423 people are fighting the blaze, using 10 helicopters, eight bulldozers, 13 water tenders and five masticators, according to the release.
Crews are now working to keep the fire from spreading toward Lowman and build fire lines to prevent it traveling north of Rock Creek.
Officials urged residents to not fly drones in the burn area, as under federal policy that immediately halts any aerial fire operations. Drones have already intruded on this fire in recent days.
The smoke has gotten thick in the area around Idaho City. Though the air quality is only at Yellow in Boise, it’s at Red in Idaho City, according to the Idaho Department of Environmental Quality.
