Analysing terrain data
The exposure grade does not take into account objective hazards (stone fall, seracs…) 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.
Named for the cornice that often forms here, this run starts steep with a few rocks to navigate.
Once through the first few turns, this slope opens up below Sasquatch Rock into an open bowl.
Watch for chunks of cornice here.
Access from either Southback gate along the Throne ridge bootpack.
Traverse around the back of the Throne to Avalanche Basin (A-Basin).
Kirner's Cornice is the last run into A-Basin before either hiking to the King summit or traversing around the back of the King to Silver Basin.
