Plummer's Ledge Natural Area, Protected natural area in Wentworth, New Hampshire, United States.
Plummer's Ledge Natural Area is a protected site in Wentworth featuring three massive cylindrical potholes carved into granite bedrock, with depths reaching 6 meters (20 feet). These striking formations dominate the landscape and create an unusual geological display on the sloped terrain.
George F. Plummer donated the property to New Hampshire in 1938, establishing its protected status under state management. The potholes themselves formed thousands of years ago at the end of the last glacial period through a slow process of water erosion.
Geologists study this location to understand the formation processes of glacial potholes through melting ice water during ancient geological periods.
Access is available from a parking area near Buffalo Road, a short drive from Wentworth village. Wear sturdy shoes since the granite surfaces are uneven and can be slippery, especially after rain or moisture.
The potholes formed when pebbles and sand were spun by glacial meltwater in circular motions, drilling into the granite like a natural bore. Such large cylindrical formations are relatively uncommon in New England.
