A 40-year-old unnamed North St. Paul woman was seriously injured after a crash near Spider Lake.
Cass County Sheriff Tom Burch reports deputies responded Saturday around 3 p.m. to the Sno-Way 1 Trail in Moose Lake Township.
The female ATV operator apparently left the roadway and struck trees, and she was ejected from the machine.
Medical treatment was initiated on the scene but she was ultimately flown by helicopter to North Memorial Medical Center.
The Pequot Lakes Fire Department, State Patrol and North Memorial Ambulance and Air Care assisted at the scene.
