SAULT STE. MARIE, Ont. - A 57-year-old woman is in hospital after being attacked by a bear in Pukaskwa National Park on Lake Superior, north of Sault Ste. Marie, Ont.

An official at the Joint Rescue Co-ordination Centre at CFB Trenton says the woman was one of three people who got off a small boat in a harbour at the park today at 8:40 a.m.

The woman suffered puncture wounds to her right side and lost a lot of blood after the bear attacked her.

Authorities say the trio got back onto the boat and radioed the rescue centre, which got in touch with park rangers.

They sped to the scene in a rescue craft, and took the injured woman to the ranger station. She was transferred to an ambulance and taken to hospital in Marathon, just north of the park.

The two other people were not hurt.
