Slate Fire grows to 5,000 acres

Slate Fire Wildfire
News – 6/10/2021

FLAGSTAFF, Ariz., June 10, 2021 — The Coconino National Forest is still working to contain the Slate Fire, which is located 23 miles northwest of Flagstaff along Highway 180 and has grown to 5,000 acres.

Windy and active wildfire conditions, along with burnout operations, are the main factors in the growth of the fire, which is still moving in a northeastern direction.

Portions of Highway 180, from mileposts 235 to 248 will remain closed for the foreseeable future while crews work to suppress the fire.

About 130 personnel are currently assigned to the fire, including three Hotshot crews, one hand crew, eight engines, two water tenders, two dozers, one helicopter and miscellaneous overhead.

Crews are currently working to manage the fire spread both east and west of Highway 180, with containment still at zero percent.

Motorists should avoid Highway 180 north of Kendrick Park, and visitors to the Grand Canyon National Park should use Highway 64 from Williams to access the entrance to the Park.

Crews plan to spend Thursday conducting burnout operations west of the highway to secure the northwestern flank of the fire, while using hand crews and dozers east of the highway to direct the fire northeast and away from Cedar Ranch. This will help herd the fire toward fuels and terrain that will be more effective in containing that section of the fire, rather than allowing the fire to move south toward the Kachina Peaks Wilderness.

While there have been no structures damaged due to the fire, crews will continue to implement structure protection around Cedar Ranch as well as several archaeological sites in the area.

Recreation sites in the area are closed, including the Red Mountain and Slate Mountain trailheads, Kendrick Cabin and a portion of the Arizona Trail from Kelly Tank (mile 603.3) and Cedar Ranch (mile 616.2).

The fire was called in by a Coconino County Sheriff's Officer at 3 a.m., and the cause is still under investigation.

Details about the Slate Fire will be posted on InciWeb, as well as Facebook and Twitter.
