An increase in acreage on the Six Rivers Lightning Complex around Willow Creek Monday was all due to the burning of unburned islands of vegetation on the interior. Firefighters have continued working on strengthening control lines and widening the buffer zones with dozers, hand crews and torching. Widespread use of drones are allowing fire officials to monitor for hot spots. The complex has grown to 41,296 acres, with 73% containment. Many evacuation orders and warnings remain in effect. Updates are at community.zonehaven.com. The complex started as a dozen lightning-sparked fires on August 5th and they’ve merged into two fires, the Campbell to the north and the Ammon to the south. Federal lands on the Lower Trinity Ranger District remain closed.
