GARDEN VALLEY, Idaho -- The Boise County Sheriff's Office has issued a voluntary evacuation notice for about 60 homes in the path of a fire.
The Calder Fire, about five miles east of Garden Valley, is one of nearly 20 sparked by lightning overnight in the Boise National Forest.
Forest spokesman David Olson says new fires are along a 40 mile stretch of the South Fork Payette River corridor east of Garden Valley.
The evacuation involves homes along the South Fork Payette River road. The fire is about a half-mile from the upper end of the road and is slowly backing down the ridge above the area, Olson said.
The Garden Valley Fire Department has set up an evacuation point at the Garden Valley School for all residents on Southfork Road, east of Alder Creek.
The Red Cross of Greater Idaho is providing supplies for any residents who decide to stay at the evacuation center.
Firefighters from the Boise National Forest, BLM, and Garden Valley Rural Fire Department are working to contain the new fires.
The majority of fires are staffed with engines, fire crews, helitack firefighters, and smokejumpers. Lookouts and aerial detection flights are searching for additional small, smoldering fires that may become visible over the next couple days.
Most of the fires are small, between a quarter acre and six acres in size. Officials say the hotter temperatures are helping the fires grow, and fire crews on scene are requesting helicopter water drops to cool the fires.
