At LDB -
the Long Duration Balloon site on the Ross Ice Shelf - various buildings
including the balloon hangers were put on berms for the winter. Most snow in
Antarctica does not so much fall as it skitters across the ice until it hits
something and sticks - so by putting these buildings on berms, the drifting
snow collects around the berms rather than the buildings, making it easier
to dig the buildings out the next summer. Buildings on the Ross Ice Shelf
are also built on skids so that they can be pulled around and on top of the
new snow each year. Otherwise they gradually become buried.
