Fragments of the earth's crust drifted together to form Alaska. And they are still very much in the process of drifting and forming. And what they have formed is already the largest state in the United States of America. It's twice as large as Texas and has fifty percent more coastline than all the states in the lower 48 put together. We'll tour the Red Onion Saloon; ride the White Pass and Yukon Railroad and check out 1,500 square miles of ice cap.
