Maine's beach dunes are slowly recovering from devastation during back-to-back coastal storms almost two years ago.

But according to the latest state beach mapping data, Popham Beach is eroding faster than any other stretch of sand in Maine.

The Popham Beach Spit area near the eponymous state park has the highest rate of negative beach change in the state, losing about 91 feet a year since 2017, according to the mapping report.

Peter Slovinsky, a coastal geologist with the Maine Geological Survey said a eastward shift in the course of the Morse River is responsible for dramatic beach losses in recent years.
