LONEROCK, Ore. (KTVZ)-- One of Oregon's largest wildfires of recent weeks, the nearly 2-week-old Lone Rock Fire, recently reached "mega-fire" status, meaning it's burned more than 100,000 acres of land.

Her report is coming up tonight on NewsChannel 21 at Five.

Condon, Ore. — The Lone Rock Fire is being managed under a full suppression strategy by the unified command of the Northwest (NW) Team 2 and Oregon State Fire Marshal (OSFM) Red Team.

Yesterday’s Activities: Firefighters efforts to contain the spread of the Lone Rock Fire continue to improve. The entire fire perimeter has some form of fireline around it. However, a few areas continue to hold heat. The small increase in acres burned is a result of fire burning interior to existing control features. The forecast severe weather passed further to the southeast and any gusty, outflow winds from the weather system did not compromise existing containment features.

Patrol and mop-up activities continued throughout Wednesday and overnight. There were a few areas where fire did cross existing lines, but firefighters were able to contain those spot fires. Crews were successful in completing firing operations and fireline construction work along Highway 19. A large crew presence remains and will continue to patrol and monitor this critical area. Containment features along Alder Creek held well, and no spot fires were reported in the area. Crews continue to patrol the area.

The remaining unburned fuel area within the fire perimeter north of Forest Service Road (FSR) 25 continued to fill in and burn, though minimal fire behavior occurred within the fire perimeter overall. Firing operations were successful around Lone Creek Road. Crews will continue to monitor and mop up the area.

Oregon Office of the State Fire Marshal (OSFM) task forces worked to mop up at least 100 feet away from homes that were protected during the fire’s most intense growth. An OSFM task force working out of Spray, Ore. also responded to a report from a homeowner that fire was moving close to their house. They were able to stop the growing fire and protect the home.

Today’s Activities: Crews will continue to patrol, monitor, and mop-up along north end of the fire. Firefighters will look for opportunities for strategic burning operations along the east side of the fire near Flatiron Spring and carry on work from night operations.

On the west side of the fire, crews will focus on continuing to mop-up the fire perimeter as well as any of the spot fires that occurred yesterday. Firefighters are also looking into carrying out strategic firing operations in the unburned section to the north of FSR 25 and east of Notch Road.

Crews will continue to mop-up and patrol the southern edge of the fire, focusing on Alder Creek and Highway 19. There will likely be isolated interior burning and smoldering in both areas, but the favorable weather conditions and existing lines should keep these areas from spreading outside the burned area. Additionally, Highway 19 closure between Spray, Ore. to Alder Creek will transition to a single lane closure with a pilot vehicle starting today at 10:00 a.m. Please use caution when traveling through the area and watch for any signage advising of hazardous road conditions.

As firefighters continue to secure the perimeter of the Lone Rock Fire, pockets of unburned fuel in the interior of the fire still exist and may continue to smolder and produce smoke. The public is encouraged to not call 9-1-1 for smoke within the interior of the Lone Rock Fire.

Structural task forces will continue mop up operations and ensure that lines near the southern and eastern edges of the fire, including Highway19, continue to hold. As the threat to homes decreases, some structural task forces will be released to support other fires in the state and return to their communities.
