The Cameron Peak fire began in August and has spread across over 270 square miles, passing the Pine Gulch Fire as the state’s largest wildfire ever.

A Colorado wildfire had raced through more than 8,700 parched, wind-blown acres in less than 24 hours on Sunday, forcing evacuation of almost 3,000 people in Boulder County as wildfires continued to batter the state and the West.

The CalWood fire began burning Saturday in Boulder County, about 50 miles southeast of the Cameron Peak Fire. That fire, the largest in state history, has burned more than 300 square miles since mid-August.

“It just exploded,” Mike Wagner, division chief with the Boulder County Sheriff’s Office, said of the CalWood fire. “We do believe multiple homes were probably lost. It’s still too dynamic to get in and begin to assess.”

Courtney Walsh posted three pictures of her burned-out, Boulder-area home on social media.
