Two young girls were seriously injured Friday afternoon in a snowmobile crash in New Portland.

The girls, ages 9 and 10, were snowmobiling on a family property off Millay Hill Road when they lost control of their 1988 Ski-Doo and crashed into trees, the Maine Warden Service said. Neither girl was wearing a helmet.

The girls were taken to Franklin Memorial Hospital in Farmington, then flown by LifeFlight to Maine Medical Center in Portland with head, chest and back trauma, officials said.

The names and hometowns of the girls were not released Friday night.

The warden service, NorthStar Ambulance, Franklin County Sheriff’s Office, and New Portland Fire and Rescue all responded to the crash.
