The Geology of D.A.R. State Park, Mt. Philo State Forest Park, Sand Bar State Park

A concise field guide to the local geology of state parks on the Lake Champlain shore that explains how to read sedimentary rock layers in the field, including strike and dip measurements, the compaction and lithification of lime muds, and the identification of fossils. It shows how fossils provide relative ages and clues to ancient marine environments, summarizes observable landforms such as terraces and tilted strata, outlines major earth movements recorded by the rocks, and provides a brief geologic time framework and fossil descriptions to help visitors interpret the park's rock record.
