Sculptured Rocks Natural Area, Protected natural area in Grafton County, United States.

Sculptured Rocks Natural Area covers 272 acres (110 ha) in Groton, New Hampshire. Its main feature, the Sculptured Rocks, is a series of narrow, sharply carved rock formations on the Cockermouth River, the longest tributary of Newfound Lake. The formations form a popular local swimming hole, and Sculptured Rocks Road runs along the same river.

The landscape took shape during the last Ice Age roughly 10,000 years ago when glaciers carved and shaped the bedrock. After the ice retreated, flowing water from the Cockermouth River continued sculpting the formations visible today.

The place attracts visitors who want to observe how water shapes stone and understand natural processes firsthand. The rock formations serve as an open classroom for anyone curious about geology.

Visit during low-water periods if you want to swim, as conditions are safer and the water shallower. Always take out what you bring in to keep the area clean and protected for others.

Sand and small stones in the flowing water act like natural grinding tools, continuously carving new patterns into the rock walls. This ongoing motion of river particles creates deeply carved holes that may look slightly different with each visit.
