Analysing terrain data
The exposure grade does not take into account objective hazards (stone fall, seracs, etc) but only the consequences of 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): Certain death in the case of a fall.
Either opt for a longer descent down the glacier from the top of the Girose lift or access the glacier via a short walk to the Col des Ruillans.
Either offers fantastic freeriding on the glacier.
If you start from the top of the Girose lift, a short hike to the Dome de la Lauze offers breathtaking views across the whole of the alps - look out for Mont Blanc in the distance. Ski the fall line towards the rocky outcrop that is difficult to identify from above.
The glacier is popular but still fairly crevassed.
After the rocky outcrop traverse skiers right over the ridge and reach the Col du Lac and re-join the Vallons de Chancel.
Don't get too carried away skiing down the glacier as it is a dead end. To avoid the steeper terrain on the Vallons de Chancel you can also traverse back to the classic Vallons de la Meije route via the Breche Pacave.
