A gap or crevasse at the junction where the ice abuts the rock at the foot of a mountain.
A chasm in the snow which can extend many hundreds of metres into the core of the ice.
Each degree is 60 nautical miles, the distance between each band of longitude that wrap the earth. 90 degrees South is the South Pole and 90 degrees North is the North Pole, with the equator being at 0 degrees.
A durable Russian cargo plane, which specialises in flying to inhospitable locations.
From the Greek work ‘Katabatikos’, meaning going down-hill, and is a glacial wind that moves from the heights with the cold air to the lowland where the air is warmer (generating a wind). As Antarctica is essentially a giant glacier, the wind blows from its centre (the high point of a dome) to its fringes.
A rock formation sticking out of the ice. In Antarctica they are the peaks of mountains that lie buried under the miles of frozen snow (much like the tip of an iceberg in the sea).
A sled on runners, which is towed by a skier and in which is stored his rations and tent sealed closed with strapping and velcro.
The plural of ‘sastrugus’. The origin of the word is Russian word for frozen wave. It’s a lumpen formation of ice that comes in many different shapes and sizes: small, large, rounded and jagged.
Overhangs of snow on a mountain ridge.
Originally animal skin and now synthetic, they are stuck to the bottom of skis to allow the skier to gain purchase on the snow when sliding but to prevent him slipping backwards (due to the direction of the hair going from from the front of the ski to the back).
A durable, small twin propeller plane used a lot in Canada. The ones in Antarctica were fitted with skis rather than wheels so they could land on the ice.
