Landforms of the North Atlantic Coast - Fine Art Print Map

The intricate coastline of the North Atlantic region reflects recent  glacial landforms and relatively minor sea level changes across a wide and flat continental shelf whose outline is much smoother. The Saint Lawrence River Valley, in contrast, is a fundamental boundary in the tectonic history of North America. The Laurentian Shield north and west of the river is the ancient North American core. The Appalachian uplands to the south and east arrived much later in successive waves. The Hudson and Connecticut River Valleys are remnants of these developments.

The sequence of Montreal Hills poking up out of the Saint Lawrence Valley (in the center of this map) is a fascinating footnote in the geologic history of the area. These local curiosities turn out to be one end of a long sequence, somewhat obscured by New England's mountain topography, and most of them under the ocean. The line extends past the Mid-Atlantic Ridge toward West Africa. The North American Plate moved across a fixed plume of molten rock coming up from the mantle. Yellowstone and Hawaii are related examples of the process.
