A physical map of Europe from 1916 showing color-coded elevations and water depths for the area extending from Iceland to the natural boundary between Europe and Asia (Ural Mountains to the Caspian Sea), and the Arctic Circle to the Mediterranean Sea. Land elevation colors range from below sea level to over 6000 feet, and water depth colors range from sea level to below 1000 fathoms. Navigable rivers, bodies of water, mountain systems, and major landform and coastal features are shown. The map also shows averaged isothermal lines in degrees Fahrenheit for January and July across Europe.
