The Grayback Fire is currently fire officials' greatest concern, according to a news release from the Boise National Forest because of its proximity to Idaho City. Though it's only 15-20 acres in size, it's also only two-and-a-half miles south of Idaho City between Grayback Gulch and Shaw Creek. The fire is burning in a densely forested area where the crowns of the trees touch each other.
Access to the fire is difficult because of the rough and broken terrain, and the Sawtooth Interagency Hot Shot Crew, along with a type II crew and a fire engine crew from the Idaho Department of Lands constructed a hand line around the fire overnight. The fire is burning directly downhill from a microwave communication tower that provides phone service and 911 dispatch services to Idaho City. Other than that, no structures are threatened.
The Mores Fire west of Mores Summit on Highway 21 didn't grow from 50 acres overnight. On the afternoon of Aug. 4, gusting winds pushed the fire uphill. It burned to the top of Pilot Peak, but it didn't damage the nearby communication site. The fire is burning in a "spotting fashion," according to the news release, meaning that it's jumping from one clump of trees to another, leaving unburned fuel in-between.
Because of that—coupled with the high elevation—this fire poses challenges to fire crews, which dug a hand line overnight and established hose lines across parts of the fire. Cloud cover is helping fire fighters more, but it could take several days to fully contain.
Another fire started in the Boise National Forest on Aug. 4, called the Eldorado Fire, but it only burned one-tenth of an acre before fire crews had it contained.
Fire officials are prepared for hectic week, according to a statement from the Boise National Forest Fire Chief Bob Shindelar.
"We are anticipating a busy day today and likely tomorrow. With the multiple new starts ... we have ordered additional crews and fire engines to support these fires and any new starts," he said. "Much of southwestern Idaho is likely to experience high winds and possible lightning over the next couple of days."
