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 Lower Caravan Traverse is your way out of Slushman's Ravine without having to go through the crux.
It starts about 40ft above the crux chute, and heads across the top of Trap Door, around to Close Call.
It can have some rocks in it, but this is definitely the easiest way out.
