The Columbia Glacier is one of Alaska's better known tidewater glaciers, both from the standpoint of tourist attraction and the model it provides for scientific investigation. In 1973 it became the object of close scientific scrutiny. In Alaska, some 50 to 60 glaciers calve into the sea, but exhibit such diversified behavior that they have baffled glaciologists for decades. For instance, some ...
Their study focused on Alaska’s Columbia Glacier, which flows into Prince William Sound and is one of the state’s fastest-retreating glaciers. The researchers reviewed a catalog of about 16,000 seismic events from two dozen Alaska glaciers, including Columbia.
Columbia Glacier, located about 40 kilometers (25 miles) west of Valdez near the epicenter of the great 1964 earthquake, is rapidly losing its battle for survival. It is the last of Alaska's 52 tidewater glaciers to begin its epic retreat from the sea. Granted, Alaska still has plenty of glaciers left, but the tidewater glaciers--those that empty directly into the sea--are on a drastic decline ...
