Firefighters contained seven lightning-caused wildfires overnight, but five new fires were reported across the Boise National Forest.
The largest of the new fires is the Ridge Fire, about 15 miles north of Lowman near Red Mountain. It has grown to over 400 acres, and fire managers said the Ridge Fire was burning "aggressively" in remote back country.
The 60-acres Summit Fire, about 14 miles northeast of Idaho City, requires nearly 200 firefighters and is being managed by the Idaho Department of Lands. The blaze is burning in fuel that creates spot fires easily, and officials say it is "proving difficult to contain."
