Already battling the largest fire in state history, Colorado is now dealing with another blaze that grew by more than 100,000 acres in a day. East Troublesome is now the fourth-largest wildfire in Colorado records. It started on Oct. 14, but overnight Wednesday it quadrupled in size."The growth that you see on this fire is unheard of," Grand County Sheriff Brett Schroetlin said during a Thursday press conference. "We plan for the worst. This is the worst of the worst of the worst. And no matter how we look at it, we can't control Mother Nature.".
