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.
Stanley East Face provides roughly 1000 feet of alpine skiing.
It has a good pitch and is fairly straightforward.
Be careful of convexities and wind loading, but in general, if there is enough snow on Stanley East Face it is far safer than Stanley Slide Path or Stanley Headwall.
