A wildfire that scorched dozens of acres and prompted evacuations this week in Marin County was sparked by a downed power line, fire officials said Wednesday.
The 152-acre blaze, called the Irving Fire, broke out around 7 p.m. Monday under Mount Barnabe Lookout in the area of Samuel P. Taylor State Park, according to the Marin County Fire Department. As of Wednesday morning, the fire was 65 percent contained. About 150 structures were threatened at the height of the fire, but no structures were damaged.
Residents on Mountain King Road, Portola Avenue and Alamo Way to Barranca Road were evacuated. An evacuation warning was also issued for residents in the upper part of Forest Knolls and Lagunitas. By 8:30 p.m. Tuesday, all evacuation orders and warnings were lifted.
