Crews battled a 96-acre, three-alarm brush fire Monday in the vicinity of Johnson’s Quarry off Johnson Road and Pigeon Hill Street. Northeast Massachusetts Emergency Alerts announced the brush fire was on Johnson Road inside of Johnson’s Quarry with state forestry crews and mutual aid companies on scene. The fire appeared to be contained by about 2:45 p.m. “Looks like we are packing up and heading out,” said Rockport Forest Fire Warden Michael Frontierro at the time about the desire to get out of the woods before sunset after which temperatures would drop. He said there were a lot of crews and a lot of cooperation in fighting the fire. The fire appeared to have burned 81 acres based on estimates by State Police who did a flyover Monday morning, said Andrew Regan.
