Anatomy of a Surge Surge When a glacier surge occurs, rapid downstream motion and stretching of the ice can advance the terminus by many kilometers. The glacier may swallow its own valley. A surge is a short period when a glacier can go as much as 100 times faster than it normally goes. dyson airwrap cost canada
