The Geology of Groton State Forest

For anyone who loves a walk among the trees and wonders why the ground feels solid beneath their boots, this guide opens the door to the quiet story written in stone. It shows how noticing the shape, color, and texture of rocks can turn an ordinary hike through Groton State Forest into a small adventure in earth history.

The heart of the book is a clear, friendly look at the granite that makes up the forest’s hidden backbone. You’ll learn to spot the light‑colored ledges on mountain summits, recognize the mottled glacial boulders that line the streams, and even distinguish the tiny mineral grains of mica, feldspar and quartz when a fresh surface is exposed. Simple explanations help readers of all ages understand how glaciers shaped the landscape and left a patchwork of stone and soil behind.

Beyond the immediate trail, the booklet offers brief connections to nearby areas, hinting at a larger granite body that stretches far beneath the Vermont countryside. With easy language and lively illustrations, it invites families and solo explorers alike to ask “why?” whenever they spot a rock, turning curiosity into a lasting appreciation for the natural world.
