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 Upper Caravan Traverse can be used to bail out of Caravan early if the conditions aren't good, or you simply want to get into Close Call.
Ski just right of the trees on the left side of Caravan, head left as the trees stop, and Caravan fades right.
This is also the top of Trap Door area.
It can have some rocks in it so be careful.
