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.
A bootpack up from the top of Showcase T-Bar leads you to the glacier, which should be open if the T-Bar is.
However, on the rare occasion it isn't and you're desperate to get a few turns of sweet pristine virgin powder then you can continue on a 10 minute bootpack up towards Horstman Peak and get a few turns in bringing you back alongside the groomed run Showcase.
This normally stays fresh even after heavy dumps because not many want to do the bootpack.
A route for those that just want to get every possible in-bounds run ticked off.
Save your energy for bootpacks elsewhere!
