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.
Sunrise, Elevator and Escalator are three steep lines going from the top of West Ridge down towards Doom & Gloom.
Escalator is the furthest and easiest of the three consisting of a 30m steep pitch which is fairly wide and unexposed.
This is a great pitch to practice your steep narrow skiing on, and a good alternative to gunning down Sunrise or Elevator.
Sometimes the pitch can leave some debris at the base.
Elevator can be compared to other double blacks such as Cockalorum, Upper McConkeys and Sapphire Bowl.
