The West Fork Complex was a massive high-elevation event fueled by Colorado’s vast stands of beetle-killed spruce.
Sparked by lightning in June 2013, the complex, made up of the West Fork, Windy Pass and Papoose fires, burned roughly 109,000 acres in the rugged San Juan Mountains. Its remoteness meant minimal structure loss despite its enormous size. (The Colorado DFPC lists its component fires separately.)
Every major Colorado fire reinforces the same lesson: the homes most likely to survive are the ones prepared before a fire starts. It highlighted how beetle-kill has turned millions of acres of Colorado forest into ready fuel. Creating defensible space, hardening the home against embers, and documenting the work for insurance and grant funding are the highest-leverage steps a homeowner can take.
