The Bering Glacier is the largest and longest glacier in continental North America, with an area of approximately 5,175 sq km, and a length of 190 km. Located in coastal south-central Alaska, it is bounded to the north by the St. Elias Mountains and to the south by the Gulf of Alaska. The Bering Glacier is also the largest surging glacier in America, having surged at least five times during the twentieth century. The glacial meltwater drains into ice-marginal lakes, the largest being Vitus Lake in the south and Berg Lake in the north. The Seal River drains Vitus Lake into the Gulf of Alaska, and the Bering River drains Berg Lake into Controller Bay. The Bering River is the site of a coal field with an estimated 35 to 65 million tons of recoverable coal. The potential development of the Bering River coal field has created a century-long battle between conservationists and developers such as the Guggenheim-Morgan Alaska Syndicate in the early 1900's, and today there are Korean interests.
