GLOSSARY

BLIZZARD. An Antarctic blizzard is a high southerly wind generally
accompanied by clouds of drifting snow, partly falling from above, partly
picked up from the surface. In the daylight of summer a tent cannot be
seen a few yards off: in the darkness of winter it is easy to be lost
within a few feet of a hut. There is no doubt that a blizzard has a
bewildering and numbing effect upon the brain of any one exposed to it.

BRASH. Small ice fragments from a floe which is breaking up.

CLOUD. The commonest form of cloud, and also that typical of blizzard
conditions, was a uniform pall stretching all over the sky without
distinction. This was logged by us as _stratus_. _Cumulus_ clouds are the
woolly billows, flat below and rounded on top, which are formed by local
ascending currents of air. They were rare in the south and only formed
over open water or mountains. _Cirrus_ are the "mare's tails" and similar
wispy clouds which float high in the atmosphere. These and their allied
forms were common. Generally speaking, the clouds were due to
stratification of the air into layers rather than to ascending currents.

CRUSTS. Layers of snow in a snow-field with air space between them.

FINNESKO. Boots made entirely of fur, soles and all.

FROST SMOKE. Condensed water vapour which forms a mist over open sea in
cold weather.

ICE-FOOT. Fringes of ice which skirt many parts of the Antarctic shores:
many of them have been formed by sea-spray.

NUNATAK. An island of land in a snow-field. Buckley Island is the top of
a mountain sticking out of the top of the Beardmore Glacier.

PIEDMONT. Stretches of ancient ice which remain along the Antarctic
coasts.

PRAM. A Norwegian skiff, with a spoon bow.

SAENNEGRASS. A kind of Norwegian hay used as packing in finnesko.

SASTRUGI are the furrows or irregularities formed on a snow plain by the
wind. They may be a foot or more deep an
