THE GEYSERS (CBS SF) — Firefighters are making progress in containing a late-season wildfire burning in geothermal energy fields in Sonoma County.
California fire officials say the McCabe Fire has consumed about 5.2 square miles, or 3,300 acres, in the remote Geyers area, home to a complex of geothermal power plants run by Houston-based Calpine Corp.
By Sunday morning, the blaze was about 35 percent contained and threatened a dozen homes.
More than 1,500 firefighters from around the state are battling the blaze, which is burning in steep, rugged terrain near the border of Sonoma and Lake counties.
The fire has been fueled by strong winds and dry vegetation, but more favorable weather conditions were assisting firefighting efforts Sunday.
Officials are still investigating the cause of the fire, which began early Friday.
