A 79-year-old Ellison Bay woman told authorities she believes she fell asleep before crashing into a tree Tuesday afternoon.

The crash occurred shortly before 3 p.m. on State Highway 57 near Valmy Road. According to the crash report, the woman was traveling north when she crossed the centerline into the southbound lane while negotiating a curve. She then drove through a ditch and across a driveway before striking a tree.

A witness told the responding deputy the vehicle had been traveling normally before gradually crossing the centerline.

The woman suffered minor injuries and was taken to Door County Medical Center for treatment.

No citations were issued. The vehicle was towed after sustaining disabling damage.
