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.
Directly under the tieback lift starting at Ptarmigan, there is a really nice line of roll overs and road crossings.
This makes for a fun pump track-esq trail that is very playful and has the potential to get some decent air.
Its not the x-games, but you might get some cheers from the lift.
