Frog Rock

Frog Rock is a large boulder in Eastford that resembles a frog due to its distinctive shape and rounded features. The formation sits along Pomfret Road and immediately catches the eye because of its unusual outline.

The boulder was transported by glaciers across vast distances during the last ice age and deposited at its current location. The area recognized its geological importance in the 19th century and designated it as a notable landmark.

The formation functions as an educational resource for geology students and researchers studying the effects of glacial movements in New England.

The site sits directly along a public road and is accessible without admission fees. Parking is available nearby, and you can view the formation easily from the roadside.

The name comes from its frog-like silhouette, which becomes especially clear when viewed from certain angles. This natural resemblance has kept the place memorable in local memory across generations.
