BOISE, Idaho -

As firefighters make progress containing two massive wildfires, they're leery of another blaze burning west of resort communities of Ketchum and Hailey.

Managers on the 85-square-mile Beaver Creek Fire say winds, low humidity and tinder-dry vegetation created unstable fire conditions Friday.

An enormous DC-10 tanker, capable of carrying 12,000 gallons of retardant, has been making drops on that blaze, which will get attention from Gov. C.L. "Butch" Otter and U.S. Forest Service Chief Tom Tidwell during their aerial tour on Friday.

Otter and Tidwell are also flying the Elk Complex and Pony Complex fires to the southwest, where firefighters are getting the upper hand a week after flames torched dozens of cabins and other structures.

Both complexes are closer to being contained, though Pine and Featherville remain under evacuation orders.
