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 (E1): Exposure is limited to that of the slope itself. Getting hurt is still likely if the slope is steep and/or the snow is hard.
Medium Exposure (E2): As well as the slope itself, there are some obstacles (such as rock outcrops) which could aggravate injury.
High Exposure (E3): In case of a fall, death is highly likely.
Extreme Exposure (E4): In case of a fall, the skier faces certain death.
A broad, steep face to the left of Exterminator, Snag Chute can be identified by two dead trees at the top.
Enter through the live trees that guard the top.
Watch for rocks at the top.
In early season, the best entrance might be on the left.
Snag Chute is really two shallow gullies that are steeper than Exterminator, which sits just to the right
