Hope Island - Narragansett Bay, RI

Geology

There are many outcrops of bedrock on the island. This bedrock is part of the Rhode Island Formation. It is Pennsylvanian-age slate, siltstone and conglomerate that has been highly metamorphosed.

The soils are extremely rocky, fine, sandy-loam derived from glacial till. This soil of the Canton and Charlton series is relatively thin in some areas and thick in other places over the bedrock. Two small freshwater wetlands have two small ponds that may be pocketed on bedrock or be underlain by tight soil material (hardpan).
