Terrain Map of the Lower 48 States

The physical geography of the United States' contiguous 48 states consists of four primary terrain features.  The western mountains stretch from Washington, Idaho, and Montana in the northwest down to California, Arizona, and New Mexico in the southwest.  To the east of these mountains lie the Great Plains, which cover the central third of the country.  The Appalachian Mountains run from northern Maine down to northern Georgia and Alabama.  The eastern coastal plain runs along the Atlantic Coast from Maine in the north to Florida in the south, then westward along the Gulf of Mexico coast to Texas.
