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 steep headwall lookers left of the 'Baldy Chutes' above Alta's Ballroom area.
The slope is steep and prone to avalanche so Alta rarely has it OPEN and Perla's may only be skied when OPEN.
It is supposedly named after a Forest Ranger who was caught in an avalanche on the slope (and was OK).
There are various lines down this headwall, most are exposed and exciting.
