Separated from the rest of the country by Canada, Alaska reaches well into the Arctic, and features mountainous wilderness, including North America’s tallest mountain, Mount McKinley (or Denali), and Native Alaskan culture unseen elsewhere in the United States. It is by far the largest state in the USA, larger than the size of California, Texas and Montana combined. The state’s territorial waters touch Russia’s territorial waters in the Bering Strait. America’s final frontier is also home to many active volcanoes, found in the Aleutians and in the coastal regions.
