Glacier Travel with Heavy Machinery
- Use extreme caution when travelling in a vehicle in glaciated terrain.
- 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
- 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
