S4E25 · Extreme Alaska

Building Extreme Alaska is about how nature engineered and built America's most rugged state, rock by rock. The State of Alaska is a vast and powerful natural structure forged over millions of years and boasts some of the world's most extreme environments. Alaska is raw and radical - natural engineering - taken to its limit. The construction zone of mountains, volcanoes, glaciers and earthquakes still keep Alaska humming. Building Extreme Alaska leads you through the working parts of this natural mechanical engineering machine.
