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.
The summit is a must do when skiing Treble Cone.
The best views are from here; you can see for miles in every direction and the highlight is the magnificent mountain of Black Peak. It's around a 20 minute hike and is always a good choice after recent snowfall as it has that extra height and catches the dry NZ snow.
It also gives you a long run back to the saddle chair. Be careful of wind and the slopes up here do get affected. Once the top is reached there are many routes to ski down; it's an open face so pick where you want to go and go for it.
