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.
Smuggler's Knob is found skier's right on the Third Bowl rope line if you've stayed right in Good Luck Glades.
As you stay right you'll have fun options open up through some glades with small rock options on the left as you merge back into Lower Third Bowl.
If you stay right towards the rope line you'll get into Big Tree Chute and finish at the bottom of Third Bowl.
