This is the last planned update for the Slate Fire

FLAGSTAFF, Ariz., June 24, 2021 — The Slate Fire, which is located 23 miles northwest of Flagstaff and caused a temporary closure of Highway 180 earlier this month, is at 90 percent containment and 11,435 acres.

While the Slate Fire is no longer active and growing, crews are hesitant to designate the fire as fully contained based on a few unburned pockets of fuel located within the fire's footprint.

Fire personnel will likely deem the fire as 100 percent contained after the area receives a significant amount of precipitation.

Windy and active wildfire conditions, along with burnout operations, were the main factors in the growth of the fire, which started west of 180 before jumping the highway and moving in a northeastern direction.

Recreation sites in the area remain closed due to a full closure of the Coconino National Forest.

The fire was called in by a Coconino County Sheriff's Officer at 3 a.m., on June 7 and the cause is still under investigation.

Details about the Slate Fire will remain on InciWeb until the fire is 100 percent contained.
