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.
Forbidden Gully is a great place to find old preserved powder and wind buff.
It starts just beneath the Outer Limits traverse, try to find the way through.
You'll be skiing protected powder between the upper sections of the aprons of Hidden and Northwest.
It is really only about 250ft long, but the turns in here are high quality.
This area never sees the sun, and doesn't get skied that much.
