NORTHERN CALIFORNIA – Cal Fire investigators said Friday they have determined the cause of last month's Wragg fire that burned in Napa and Solano counties.
The agency's investigators concluded the wildfire was the result of a vehicle exhaust contacting dry grass, which then ignited the surrounding brush and the vehicle as well.
The Wragg Fire was reported at 2:24 p.m. Wednesday, July 22, off of Highway 128 near Wragg Canyon Road and the Lake Berryessa Dam.
The fire burned through heavy brush and steep rugged terrain, eventually ending 4 miles west of the city of Winters and just north of Mix Canyon Road near Vacaville, Cal Fire said.
During initial operations a Cal Fire helicopter was used for the emergency rescue of multiple hikers in the Cold Canyon area. One hiker suffered a heat related illness and was transported to a local hospital by ground ambulance.
The fire burned 8,051 acres, destroyed two outbuildings, and damaged four outbuildings and one residence. The Wragg fire was fully contained on Aug. 5, according to Cal Fire.
“With the critical fire conditions we are seeing this year combined with 4 years of drought, we are asking the public to be extra cautious in not sparking a wildfire,” said Cal Fire Unit Chief Scott Upton. “With hunting season and other outdoor activities at their peak it is imperative that we remain aware of how easily dry grass can ignite a wildfire with devastating consequences.”
With drought conditions, Cal Fire continues to urge the public to be careful outdoors. Pulling over in dry grass can easily ignite a wildfire.
