Screw Auger Falls


Screw Auger Falls is a beautiful waterfall in Grafton Notch State Park (Maine) that features a stunning 25-foot plunge. The waterfall is most known for its plunge, but there are some small cascades, potholes, and shallow pools. The waterfall is a very popular location in the summer because visitors love sunbathing along the rocks and exploring the gorge. Screw Auger Falls is also popular due to the fact that it is only located a few hundred feet from the parking lot, making it extremely accessible. 

The waterfall was formed some 12,000 years ago when melting glaciers influenced patterns of the Bear River’s flow by vastly increasing water runoff and its erosive power. A glacier blocked the north end of Grafton Notch causing huge quantities of meltwater to be channeled southward. The river, loaded with sand, gravel, and cobbles released from the ice, began cutting into the granite ledge, producing the deep, contorted gorge. In time, the glacier retreated further north, and the Bear River returned to more normal levels.
