Glacier Travel with Heavy Machinery
- Use extreme caution when traveling in a vehicle in
- There is no practical system that allows vehicles (other than
snowmobiles) to be safeguarded in the event of a crevasse fall.
- Vehicles should only be used on predetermined safe routes.
Go around crevassed areas, leaving a wide margin of safety.
- If your field work requires travel through glaciated areas, use
rigorous research, interviews, and investigation to determine any
previous history of the route. Many "new" routes have an
interesting and sometimes disastrous history.
- Before committing heavy equipment to a route in unknown
terrain, reconnoiter the route first by aircraft, and then by
snowmobiles and sledges.
- Always carry survival gear in the cab of the vehicle. It's a
good idea to also carry a spare set of clothing, in case fuel or
other liquids leak onto your clothes. Wear a climbing harness
to facilitate a quick rescue.
- If a vehicle breaks through a small crevasse, continue driving
forward and the tracks may climb out of the crevasse.
- If you fall into a crevasse with a vehicle, kill the engine
immediately to prevent carbon monoxide buildup in the crevasse,
and subsequent carbon monoxide poisoning.
