WALDEN — The Ryan fire has more than tripled in size in less than a day.

On Sunday afternoon, Sept. 16, U.S. Forest Service spokesperson Aaron Voos estimated the fire had burned about 500 acres near the border of Colorado and Wyoming, north of Mount Zirkel Wilderness Area. By Sunday evening, the fire was reported at 1,832 acres, according to a Forest Service news release.

The fire started in the northern edge of the Mount Zirkel Wilderness in Jackson County, about 20 miles northwest of Walden. It was first reported late Saturday evening. The Ryan fire quickly spread north, crossing Forest Service Road 80 and the state line. The fire is now burning in Routt and Medicine Bow National Forests.

The cause of the fire is under investigation.

Firefighters initially battled the flames using ground crews and aerial support. High winds grounded helicopters, and rapid growth made it too dangerous for ground crews to continue fighting. Firefighters then shifted their attention to evacuating campers and hunters in the area.

On Sunday evening, the Forest Service said all known camps within the fire's path were evacuated.
