When the blizzard was over, it was necessary to clear the snow from the tractors and sledges. Fortunately, on our way south, we had left our third tractor at a depot not far away, so it was possible to go there with a Snowtrac and retrieve it - checking a safe route and returning very carefully. The first tractor was relatively easy to extract, the "sideways" one proved a problem. First (as above) we tried lifting it sideways with two tractors, using steel cables and bridging timbers: all we achieved was to shake the tractor further down the slot while breaking cables and chains.
