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 Bitter End is a great wide open run that starts out in on the open face below Bathtub and continues down a wide tree alley.
It is also the Southern boundary of Bridger Bowl.
It gets skied often and can get sun affected and even some moguls.
Either hike up and ski the Bathtub and ski fall line into the Bitter End or you can traverse all the way across Mundy's to get it.
After you ski about 500ft of wide open turns, there will be an obvious rollover and boundary marker signs.
You will want to obey, and head left avoiding a very large cliff beneath you.
