D5 "Monica" nearly buried in snow after a blizzard. Drifting snow collects quickly in the lee of stationary objects. This is after just a few days of high wind. A D5 or D7 does not have sufficient engine or hydraulics power to break free under its own power. The only way to free the machine safely is through backbreaking manual work with a snow shovel. Wilkes Land, Autumn 1986.
