FRANKTOWN, Colo. — A large fire destroyed a barn on Saturday afternoon, the Franktown Fire Department said.

The fire broke out about 1:45 p.m. on Castle Pointe Drive not far from Castlewood Canyon State Park.

No people or animals were injured, fire officials said. A large plume of smoke was visible for several miles.

Hay will make full it difficult to fully extinguish the fire, so crews will stay on the scene throughout the afternoon to make sure it does not spread into nearby vegetation.

The cause of the fire is under investigation.
