The Kincade wildfire burning just northeast of Geyserville in north Sonoma County had scorched 21,900 acres and was 5% contained, according to a Friday morning estimate from Cal Fire.
A firefighting force of about 1,300 personnel was assigned to the Kincade fire (including at least 70 personnel, 10 engines, 2 fire crews, 1 bulldozer, and 1 water tender from Marin) which ignited during a windstorm Wednesday night in the remote geothermal energy production area of The Geysers in the Mayacamas Mountains. It burned southward into the edges of the Alexander Valley, destroying at least 49 structures.
