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.
Sunrise Traverse is a very exposed traverse from the Big Bang entrance to Couloir Extreme allowing access to Sunrise Chute and Upper Feather Trees.
It crosses above a large cliff band which can fill in fairly wide depending on the snow year.
Nonetheless, this is a No Fall Zone.
