Skidoos

Skidoos

We used two Bombardier skidoos (SWT 10 and 08) for traversing Whitehall Glacier. These skidoos are easier to drive and to start than the older Alpine II models. However, in soft snow the pulling capacity of the Bombardier is less than that of an Alpine II and at steeper slopes, we had to assist pushing the Nansen sledge manually to avoid the skidoo to be drawn down-slope by the weight of the sledge. Also, in soft snow, a second person had to sit on the front skidoo to enhance traction, which was possible once we radar scanned the area for crevasses. In addition, both skidoos showed signs of fatigue with hairline cracks developing in the chassis of the variator. Overall, the skidoos were reliable and performed well. We are grateful for the in depth discussion with Scott Base mechanics T.Griffith-Jones prior to our field deployment on maintenance and safety issues as well as on necessary adjustments for high elevation deployment. The skidoos were well prepared and fitted with spare parts and we received professional and useful advice during field deployment via radio.
