Firefighters had to rescue a 60-year-old woman who became stuck waist deep in the mud while digging for clams in Wells. Capt. Jeff Cullen says firefighters responded to the mud flats off Drake’s Island just after noon on Monday, and about a half hour before low tide. The firefighters were able to walk out to her and use a 20-foot roof ladder to help get her to safety. The woman’s name was not released, but Cullen says she was a visitor to the area. He tells The Portland Press Herald, she was checked out by rescue workers but did not require medical attention.
