The Cameron Peak fire in Larimer County's causing closures in Rocky Mountain National Park.
Park officials call it an abundance of caution, to close Old Fall River Road. Also closed: the trailhead at Chapin Pass. Trail Ridge Road remains open.
The fire's now at more than 24,000 acres, with just 6% containment. There have been some evacuations. Red flag warnings are up through Monday, and officials say more closures are possible.
