Geology of New England These settlers could have moved to recently formed dune fields, which were produced by wind erosion of glacial outwash deposits, such as those found in the Ohio Valley, in the Hudson and Connecticut River valleys, and in the Israel River valley. Early human settlers could have populated these river valleys in order to observe the caribou migrating northeast along the newly formed rivers. Geology of New England New England is a region in the North Eastern United States consisting of the states Rhode Island, Connecticut, Massachusetts, New Hampshire, Vermont, and Maine. Most of New England consists geologically of volcanic island
Geology of Rhode Island Pleistocene glaciations. The state's geology is part of the broader geology of New England. Rhode Island is divided into two distinct physiographic regions. The Eastern Highlands occupy the northwestern interior of the state, near the state line with Connecticut while the majority of the state's land area is grouped with the larger Atlantic Coastal Plain that extends along the eastern seaboard of the US. Rhode Island is the only state in New England formed entirely atop basement rock from the microcontinent Avalonia. The bedrock of Rhode Island first took shape with the emergence of a volcanic arc near a subduction
