WALSENBURG, Colo. (AP/CBS4) – Firefighters are making progress on a wildfire that has forced people in 300 homes near Walsenburg to flee.

Fire officials say the 19-square-mile wildfire burning seven miles southwest of Walsenburg was 10 percent contained Sunday. But officials say a portion of the fire is in heavily timbered areas and there’s great potential for growth.

The East Peak Fire was caused by lightning Wednesday afternoon. Fire officials say structure protection remains a priority for crews.

Fourteen buildings have been destroyed so far.

“We’ve got important documents, photos that we don’t have negatives for, jewelry that is worth money,” an evacuee said. “We’re ready to go at a moment’s notice.”

The John Mall High School in the northwest part of the city is housing an American Red Cross shelter.
