July 3 (UPI) -- A wildfire in Northern California has burned 70,000 acres as of Tuesday, fire officials said.
Known as the County Fire, it began on Saturday afternoon in an unincorporated area of Yolo County before exploding in magnitude. Cal Fire said it was 5 percent contained Tuesday.
More than 2,100 fire fighters have worked to control the blaze, which has threatened at least 116 structures and has crossed into Napa County. Fire crews have used 177 engines, 12 helicopters and 50 dozers to try and contain the fire, Cal Fire said.
