Iliamna Volcano in Alaska

Alaska. A great land with an even greatest history. Up until 1867 Alaska was under Russian ground. In this year czar Alexander the 2nd sold Alaska to the USA and in 1959 Alaska was named the 49th state of the United States of America. Alaska’s first expedition started in 1741 by Vitus Jonassen Bering and was later continued by James Cook. But in the start of the 19th century many more expeditions followed so as to discover this beautiful land. It is said that in Alaska there are 13 active craters. The most significant and historical ones are Redoubt and Iliamna. They rise above the Alaska –Aleutian subduction zone and are two of the 52 active volcanos that exist in this area.
