Analysing terrain data
The exposure grade does not take into account objective hazards (stone fall, seracs…) 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.
There are various ways to access the back of Treble Cone.
Either hike up to the Summit Ridge line and drop in anywhere along there, or hike up to the left side of the summit ridge as if you were going to Wedding Cake Rock.
The backside is a massive open face with small gullies and playful terrain.
It does get sun affected but as long you head there in the morning it's fine.
You can go down as far as you like, but it's not worth going all the way to the valley floor.
You're better off stopping as the terrain flattens out and skin back up to Wedding Cake Rock, probably taking around 1.5 hours if you're fit. On a pow day or spring corn, it's a lot of fun and there's nothing too technical so it's great for the casual tourer.
All avalanche gear is needed; it's still backcountry and away from the resort boundary
