MASON CITY — Mason City firefighters are battling their second major fire in a month as the Mystic Lanes bowling alley has suffered major damage.

Firefighters were dispatched to the fire at 2571 4th Southeast at about 9:15 PM, where on arrival they found smoke and flames coming from the building.

Fire departments from Mason City, Clear Lake and Nora Springs were still on the scene as of 11:30 PM Sunday night trying to control the fire. A cause has not been identified.

Power was cut off to the far eastern portion of Mason City as a precaution.

The fire leaves Mason City without an operating bowling center after the Rose Bowl was damaged by fire in January 2014.
