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.
Heading south from the Upper Weather Station takes you into the Pumphouse area, which offers about 650 feet of tree skiing.
The top of Pumphouse is significantly flatter than the bottom.
Since it has a southern aspect, Pumphouse is much better when there is new snow.
