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.
The Rats Nest is an alternate, but not generally easier entrance into Great Scott.
There is a rope to help you side step down the steep and exposed rocky section into Great Scott.
To find the rope use the Silver Fox gate then immediately stay high left and you will see the Rats Nest gate.
This can be a great way to ski Great Scott if you are intimidated by the standard entrance, however Rats Nest is no peachy entrance either, and your skis will hate you.
