Forest Service officials were still uncertain Thursday what sparked the blaze that has blackened 110 acres of the Coconino National Forest 19 miles north of Strawberry.
The Clover Fire, which was spotted at 1:30 p.m. Wednesday, sent large plumes of smoke high into the sky west of Clint's Well as if to emphasize the extremely high fire danger threatening northern Arizona forests.
As of Thursday, the fire was 80-percent contained, Emily Kinney, spokesperson for the Coconino's Blue Ridge Ranger Station, said. Officials expect to have the fire under control by tonight (Friday).
A fire is contained when firefighters have drawn a wide line in the dirt around the fire, eliminating combustibles and "containing" the fire. A fire is considered under control when the fire can't grow beyond its current boundaries.
Three water tenders, including a 3,000-gallon tender from the Pine-Strawberry Fire Department, have been shuttling water to the fire line, where firefighters are using thousands of feet of hose to battle the blaze with foam and water.
Firefighters on the scene Wednesday said a sudden shift in the wind changed the fire's direction and placed a truck and a three-man crew in the fire's path.
They had hauled 200 gallons of water and firefighting tools into the area in a Forest-Service-green pickup truck, but they couldn't get the truck started again to escape the blaze.
They hiked safely out of danger on foot, but the truck was destroyed.
