Sawmill fire burning in The Geysers 90 percent contained

The four-day-old Sawmill fire burning in The Geysers was 90 percent contained Wednesday night, according to a Cal Fire news release.

Fire crews have battled the blaze since Sunday morning in the northeastern part of Sonoma County. The fire’s footprint was reported at 1,609 acres, up from 1,500 acres due to better mapping of the blaze, a Cal Fire spokeswoman said.

Crews focused their effort Wednesday on strengthening and extending the containment lines. The firefighting force was reduced to four crews and a total of 241 people by 6 p.m.

Cal Fire reported two minor injuries and no buildings damaged in the fire.

The fire’s cause remains under investigation.
