Nearly a week after the destructive Mountain Fire destroyed more than a hundred buildings and torched tens of thousands of acres of brush in Ventura County, firefighters are defending their response to the blaze as some residents return to their burnt homes.

Mountain Fire initially started 8:51 a.m. Nov. 6 in Ventura County. It has burned 20,630 acres after being active for five days. By Monday morning, a crew of 2,812 firefighters effectively contained 36% of the fire. The cause of it is still under investigation.

At least 200 structures, including homes, have been destroyed alongside an additional 90 damaged in the ongoing wind-fanned Mountain Fire in Ventura County, fire officials said Tuesday morning.
