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.
Now you're talking about some of the most extreme skiing Taos has, and most people have never heard of it.
This line requires traversing a narrow spine then it's a couloir plunge into the bottom of Dog Leg and Hunziker Main.
This is serious stuff here so never go alone and take an informed guide with you if you absolutely insist on going.
Don't be surprised if it's roped off even on the best days.
