Slate Fire Wildfire
News – 6/9/2021

FLAGSTAFF, Ariz., June 9, 2021 — The Coconino National Forest is still working to contain the Slate Fire, which is located along Highway 180 and has grown to 2,000 acres.
The fire originated on June 7 approximately 23 miles northwest of Flagstaff on the west side of U.S. Highway 180, adjacent to the Kaibab National Forest. It is currently moving in a northeast direction.
Portions of Highway 180 from Cedar Ranch to Kendrick Park will remain closed for the foreseeable future while crews work to contain the fire.
About 150 personnel are currently assigned to the fire, including four Hotshot crews, one hand crew, eight engines, two water tenders, two dozers, one helicopter and miscellaneous overhead.
Crews plan to spend Wednesday working to secure Cedar Ranch using indirect suppression strategies.
Motorists should avoid Highway 180 north of Kendrick Park, and visitors to the Grand Canyon National Park should use Highway 64 from Williams in order to access the entrance to the Park.
No structures are threatened at this time. 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.
