The Geology of Calvin Coolidge State Forest

"The Geology of Calvin Coolidge State Forest" by Harry W. Dodge, Jr. is a scientific publication written in the late 20th century. The book serves as a resource for visitors to the Calvin Coolidge State Forest Park in Vermont, aiming to educate readers about the geological features and history of the area. It explores the complex processes and time spans that shaped the park's landscape, focusing primarily on the diverse rock formations present. The text provides a detailed examination of four geological formations within the park—Pinney Hollow, Ottauquechee, Bethel, and Missisquoi formations—each with its unique characteristics and historical significance. Through the application of geological principles, Dodge reconstructs the area's geologic history, detailing how ancient seas contributed to the formation of sedimentary rocks, which later underwent metamorphosis due to earth movements. He elaborates on the laws of geology, such as uniformitarianism and superposition, allowing readers to understand the significance of the park's rocky landscape and its evolution over millions of years, influenced by factors like glaciation and sediment deposition. The book encourages readers to engage with the environment, fostering a deeper appreciation of the natural world that surrounds them.
