Exposure

Exposure

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.

As well as the slope itself, there are some obstacles (such as rock outcrops) which could aggravate injury.

Description

Less steep than some of the Brevent couloirs but not to be underestimated.

Although shorter than the other Brevent couloirs the Allias offers a wider canvas perfect for opening up.

After following the "Charles-Bozon" piste hang a right before "Altitude 2000" into the wide couloir leading you into the Brevent bowl and then the track down to Chamonix- make sure there is enough snow to get you down or it's a long walk!
