POWNAL, Maine — Pownal firefighters on Saturday carried a woman off Bradbury Mountain after she slipped and fractured her ankle.

A friend of the woman’s called 911 from a cellphone at about 12:55 p.m. after she slipped on rocks on a “very tough, steep” section of terrain, Deputy Chief Dick Hogue of the Pownal Fire Department said Monday.

“She was about as far away from the parking lot as you could get,” Hogue said. The woman suffered “a fairly substantial fracture.”

The rescue effort took nearly three hours and involved about 16 people, he said.

Freeport rescue workers took the woman to Maine Medical Center.
