Dan O'Neill: author on the Bering Land Bridge

Award-winning Fairbanks author Dan O’Neill's 2004 Book The Last Giant of Beringia: The Mystery of the Bering Land Bridge not only tells the story of the historic land bridge that connected Siberia to Alaska, but also of the scientists, in particular geologist Dave Hopkins, who worked so hard to synthesize the evidence that has led to our current understanding. 

During periods of glaciation – otherwise known as Ice Ages -- our sea levels dropped by as much as 480 feet. The Bering sea is only about 160 feet deep. Therefore, during these periods of global cooling what today is the Bering Strait was dry land -- land that supported plant life and animals.
