The geological composition includes significant amounts of gneiss and schist common to the Connecticut River Valley region.
Chatfield Hollow State Park is distinguished by its unique geological features, including small caves, rock shelters, and a deep, spring-fed ravine carved by Chatfield Hollow Brook. The park landscape features a mix of deciduous forests, rugged outcroppings, and water-based recreational areas. Visitors can explore the remains of historic mill sites from the 19th century scattered throughout the grounds. The area is home to an artificially created pond that serves as a focal point for seasonal swimming and fishing activities. Several miles of marked hiking trails traverse the uneven, forested terrain. The site was once part of the CCC-developed lands, with remnants of stone construction visible in several structures.
