That was just before state fire investigators officially concluded that Pacific Gas & Electric equipment had sparked the devastating Camp Fire — a blaze that experts have said became the state’s deadliest in large part because of the speed with which it spread.

Cal Fire estimated that at one point, flames were consuming the equivalent of a football field each second. Ultimately, it would kill 85 people and destroy 18,804 structures.
