Alaska: Physical Geography

Alaska from NOAA

Alaska’s geography varies greatly from north to south and from sea level to its highest peak, Mt. McKinley – at 20,320 feet (6,194 m), the highest mountain in all of North America.

The state of Alaska is commonly divided into four major geographic subregions: the Pacific Mountain System, the Central Up- and Lowlands, the Rocky Mountain
System of Alaska, and the Arctic Coastal Plain.
