A fire in Trinity County has been downgraded in its size estimate. The Flat Fire started at 3:15PM Tuesday afternoon when a vintage car rolled over on Highway 299 near the Cedar Flat Picnic Area east of Burnt Ranch. It came to rest on its roof and the driver was pulled to safety before the car became engulfed in flames. The fire spread to roadside vegetation and rapidly climbed the very steep mountainside. The highway was completely closed for a few hours, and one-way traffic control continued through the night. The fire had been estimated at 100 acres as it burning north toward Ironside Mountain, with several structures threatened. On Wednesday the Forest Service said it was actually about 75 acres and 15% contained. Structures are no longer threatened. Resources on the fire include five air tankers dropping retardant, two helicopters dropping water, as well as smokejumpers, engine crews, dozers and ground crews. The terrain is extremely rugged and difficult to access. The Burnt Ranch Campground is being used by firefighters, but all the other campgrounds in that area are open. Drivers can expect some delays.
