The Geology of Calvin Coolidge State Forest

Each summer the pine‑scented valleys of Calvin Coolidge State Forest draw campers, hikers, and picnickers seeking both recreation and a glimpse of natural history. This guide invites anyone with a curious mind to step beyond the trailhead and discover why the hills and valleys look the way they do. By blending clear explanations with local maps, it turns a day‑trip into an adventure in earth science.

The book introduces the three cornerstone principles that geologists use to read the stone record: uniformitarianism, superposition and faunal succession. Simple analogies—like comparing rock layers to a layered cake—make these ideas easy to grasp, while vivid examples show how modern rivers and deltas echo ancient ones preserved in the forest’s rocks. Readers learn to treat each outcrop as a page from a deep‑time storybook.

Armed with these tools, visitors are guided on a journey 550 million years into the past, visualizing ancient seas, volcanic intrusions, and the slow rise of the Green Mountains. The narrative connects the present landscape to its geological past, offering a richer appreciation of the scenery that surrounds every campsite and trail.
