The small chunk of North America enclosed within the state boundaries of Connecticut and Rhode Island includes parts of at least six former continents, microcontinents, and volcanic island chains, each with its own geologic history. Roadside Geology of Connecticut and Rhode Island introduces readers to the sequence of mountain-building collisions that welded the pieces of land together and to the subsequent upwelling of magma that nearly broke them apart again. Twenty road
guides, complete with maps, photographs, and diagrams, locate
and interpret the rocks and landforms visible from the state s
highways and at nearby parks and historic sites. Readers will discover stretched pebbles at Purgatory Chasm, folded marble
at Kent Falls State Park, Eubrontes footprints at Dinosaur State Park, and glacial moraines protruding from the waters of Long Island and Block Island Sounds.
