Large masses are also always falling down from the ice-front.
The 'Aurora' retreated to the open sea, and headed to the west in search of a break in the ice-front.
This is not the case of a mere temporary recession of the ice-front.
The evidence for this is found in the presence of a continuous, terminal moraine, at or just in advance of the present ice-front.
In the oscillations of the ice-front marking the final retreat of the Alpine glaciers there were three epochs of advance.
No mere temporary retreat and re-advance of the ice-front can account for these phenomena.
