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.
The trees around Pyramid are great fun, providing you stay safe; ride in pairs at least, with a helmet and a plan.
Look out for tree stumps and undergrowth in early season; a foot of powder can obscure a lot.
Best to wait until it's really filled in.
In the later season.
Taking a line from Pyramid to Lower Powderhorn helps ensure you've got a definite run out.
Do watch out for clumps of bushes that grow there, which create bubbles of snow that you can sink down into, which sucks.
