Sculptured Rocks Natural Area
Ancient Glacial Potholes in Cockermouth River — Sculpted Rock Gorge, Swimming Holes, Cascading Falls, Short Trail, Groton NH
Sculptured Rocks Natural Area is a natural area at 251 Sculptured Rocks Road, Groton, Grafton County, New Hampshire. The area features spectacular glacial potholes sculpted into bedrock by the Cockermouth River, a narrow gorge with sculpted rock walls and natural swimming holes, cascading waterfalls connecting pot-shaped basins, a short interpretive trail along the gorge rim, and one of New Hampshire’s most dramatic geological formations.
Sculptured Rocks is New Hampshire’s geological masterpiece — the Cockermouth River has carved cylindrical potholes and sinuous channels into solid schist bedrock over thousands of years. The swirling water carries sand and pebbles that act as natural drills, grinding the smooth, bowl-shaped basins deeper with each flood.
The narrow gorge creates natural swimming holes that attract visitors on summer days — the water flows between sculpted walls, dropping through cascading waterfalls from one pothole to the next.
