A video shot by a Berkeley crew dispatched to the Tubbs fire in Santa Rosa shows just how shocking the scene was early Monday, Oct. 9.

Told they were responding grass fire, the strike team was amazed by what they saw - instead structures burning all around them

"Look at this, man, all kinds of structures are burning," one firefighter could be heard saying. "Are you serious?," asked another in disbelief.

The fires that have burned through Sonoma and Napa counties have destroyed thousands of structures and killed at least 42.
