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.
Not for the faint-hearted! As you might imagine from its name, the pencil is a long, thin chute accessed via a cornice (the size of which depends on snow conditions) which shoots you out onto Double Rubble.
The snow will be good here - at least for the first person! The entrance can get pretty scraped out though from the access side-slip in that people tend to make.
Ensure the run below is clear before you send it though as you'll be coming out with some real hot sauce! Check the chute and snow conditions out from Double Rubble beforehand.
