Cricket and I had our driving test this week, our introduction to the conditions and hazards associated with driving at Scott Base, Antarctica.
Transportation has changed a lot since the days of the early explorers. Until the late ’80s dogs were used for travel, however, snow machines and vehicles have taken over. Our instructor was Lex, the mechanic at Scott Base this year. Lex is an amazing mechanic as he can repair and modify diesel, petrol (gasoline) and two-stroke engines and hydraulics, all of which are in the fleet. He is a very busy man.

For the most part, when travelling between the American Base McMurdo and the Pegasus air strip, we use trucks modified for travel down here. The larger tyres are used because the standard snow tyre would wear out the road too quickly. The vehicles are all four wheel drive. The fuel used is also modified to withstand the low temperatures: the diesel vehicles use AN8, an aviation fuel containing Kerosene; the petrol (gas) equivalent is Mogas, it has reduced octane.

The vehicles all have block heaters to keep the oil and lubricants flowing when not running and in-cab heaters, these are activated when the vehicle is plugged in. At McMurdo there are several dedicated plug-in places just for Kiwi’s. We also have a “hitching rail” here at Scott Base for plugging in.
