Authorities say strong winds have fueled a wildfire west of Fort Collins and forced the evacuation of more than 300 homes.
The blaze has already destroyed an outbuilding, a motorcycle and an all-terrain vehicle, but no injuries have been reported.
Larimer County Sheriff's spokesman John Schulz tells The Associated Press early Sunday that about 335 homes had been ordered evacuated in three areas: south of Buckhorn Canyon, east of Crystal Mountain Road, and around Redstone Canyon.
The rugged, hilly area is located about about 15 miles west of Fort Collins.
Centers for evacuees are being set up with the help of the Red Cross.
Shulz says 50 mph winds have helped expand the fire from 25 acres Saturday to about 800 to 1,000 acres early Sunday.
