The Hill Fire in Ventura County is now completely contained, but there are big questions about what started it.
Investigators say they’ve been able to rule out accidental causes for the 4500 acre blaze, and now think some type of human activity triggered the fire.
It’s believed to have started in the area of Hill Canyon Trail, which is in the Santa Rosa Valley between Hill Canyon Road and Santa Rosa Road.
Investigators are looking for potential witnesses, including anyone who may have been in the area of the trail between 10 a.m. and 3 p.m. November 8th.
The fire forced thousands of evacuations, but firefighters were able to keep it from destroying homes.
