Connecticut and Rhode Island. Such a little chunk of North America captures so much geology. Parts of at least six former continents, microcontinents and volcanic island chains all pushed together, each with its own geologic history.
Continents crashing together built enormous mountains and welded the pieces of land
together. A subsequent upwelling of magma then nearly broke
them apart again.
The twenty road guides Roadside Geology of Connecticut and Rhode Island use full color maps, photographs,
and diagrams to locate and interpret the rocks and landforms visible from the state's highways, nearby parks, and historic sites. A Block Island tour is included.
You'll tour Purgatory Chasm's stretched pebbles, the folded marble of
Kent Falls State Park, Eubrontes footprints at Dinosaur State Park, and
glacial moraines protruding from the waters of Long Island and Block
Island Sounds.
