Video – “A Dangerous Glacier Grows Inside Mount St. Helens’ Crater”
According to Charlie Anderson, independent geologist and vulcanologist, the crater, officially named Crater Glacier, is growing unusually fast. In fact, its, and is the fastest growing glacier in the continental United States
This video appears to be rather old, but even today Crater Glacier glacier is still growing and advancing at a steady rate of about 25-30 meters per year (80 to 100 feet per year), according to the USGS. The glacier is advancing across the crater floor and dropping into the Loowit and Step Channels.
