The exposure grade does not take into account objective hazards (stone fall, seracs, etc) but only the consequences of 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): Certain death in the case of a fall.
The East Face of Fisher Peak is a nice way to end the day after lapping Rob's Knob.
Its about 600 feet vertical, but wide open and moderately pitched.
Skin or boot from the top of Rob's Knob about 200 feet to gain the ridge just South-west of Fisher Peak.
