Analysing terrain data
The exposure grade does not take into account objective hazards (stone fall, seracs, etc) but only the consequences of 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): Certain death in the case of a fall.
Hochwurzen has steep and not too tight forest, although for the really steep lines close to the top and all visible from the pistes there needs to be a lot of snow and really safe conditions at the same time.
As the most commonly ridden tree runs are between the pistes you can't get lost either, as you'll always get back to the pistes anyway.
As usual don't ski into areas where there are small trees and also don't shoot out on the pistes without looking.
Regarding riding: There are many piste and forest roads crossing- if you are approaching too fast, the compression can be quite uncomfortable.
