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.
Route finding on SE Throne Left is even more challenging that SE Throne Right.
For this reason, some of the lines are rarely skied.
This steep run faces the sun and gets stripped by the prevailing winds.
Under the right conditions however, this can be relatively untracked.
Access from the upper Southback gate at the summit of the Throne.
Follow the treed ridge on the skiers left until the slope opens up below.
The further down the ridge you go, the more open it gets.
There are two main runs in SE Left.
The first one is a steep face that eventually drops away on the left, forcing you right toward the bottom of SE Right.
Left of this face find an open couloir that narrows towards the bottom before opening into Avalanche Basin.
Numerous other lines exist for those willing to launch off cliffs.
Watch for rocks during shallow snow conditions.
