Analysing terrain data
The exposure grade does not take into account objective hazards (stone fall, seracs, etc) but only the consequences of the skier falling.
Low Exposure: The route is well protected or easy enough that protection is not required.
Medium Exposure: The route features some exposed and/or difficult to protect sections.
High Exposure: Much of the route is difficult to protect and a fall could be disastrous at certain points.
Extreme Exposure: The majority of the route is "no fall" terrain.
