Six pondlets (originally constructed as fire suppression pump ponds) are located on the property: Chickering Pond, Echo Pond, Notch Pond, June Pond, Little Chickering Pond, and part of an unnamed sixth pond. The rugged, rocky terrain of Rocky Woods was formed via glacial action during the last ice age through glacial plucking and scouring.During the colonial 18th century, Rocky Woods had been divided into common land woodlots. A network of logging roads, paved with asphalt shingle scraps, were cut through the property in the 19th century and used to transport granite quarried on site.
