Two fires encompassing thousands of acres in Grant County and Douglas County were extinguished Monday.
A home, a shop, an outbuilding and several vehicles were confirmed destroyed in the McConihe Flats fire near Moses Lake.
No structures were destroyed in the Douglas County blaze.
The fire near Moses Lake began Sunday afternoon in a field near Stonecrest Road, said Kyle Foreman of the Grant County Emergency Management Office.
Investigators determined fireworks caused the blaze. “They know the parties involved,” Foreman said, and information has been forwarded to the Grant County prosecutor’s office for possible criminal charges.
The final size of the Moses Lake fire is estimated at 1,200 to 1,400 acres. Crews were on scene overnight Monday watching for flare-ups.
Fire crews also wrapped up their work Monday at the Crescent Bar fire in Douglas County. The Spokane County Incident Management Team, which oversaw firefighting efforts, calculated the burned area at 2,470 acres.
The Crescent Bar fire initially threatened several homes before heading into the sagebrush-covered hills, said Capt. Scott Crawford of the Spokane Valley Fire Department.
“It turned into kind of a big deal,” he said.
Investigators thus far haven’t been able to determine the cause.
