It began shortly after 1:00 pm near Cobb with multiple reports of a small brush fire near the intersection of High Valley and Bottlerock Roads. It quickly spread and by 6:30 PM PDT, it had burned more than 10,000 acres. By Sunday, the thirteenth of September, the fire had reached 50,000 acres and had destroyed much of Cobb, Middletown, Whispering Pines, and parts in the south end of Hidden Valley Lake. The fire ultimately spread to 76,067 acres, killed four people and destroyed nearly 2,000 buildings, before it was fully contained on October 15, 2015, causing at least $921 million in insured property damage.
