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.
Tanner Gulch is considered a “classic couloir” that begins with a headwall chute, opens up to a large apron and open bowl with fun rolling terrain all the way to the bottom.
You would go up the upper western chute, with the reward of a wide, steep, sustained 40 degree descent.
It is also a an avalanche terrain trap, as it is a long sustained funnel, with the lower fifth serving as a depository for any debris that rips from above.
To the saddle its a 4.3 mile hike, beginning at 7,400 ft elevation, and topping out 3,400 vertical ft higher (By comparison, the highest you can obtain at a Utah ski resort is 3,243 vertical feet at Snowbird).
