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.
A serious glacier run in the spectacular Argentiere Glacier basin.
Head to the R of the rocky Rognon, then straight down, leaving a characteristic rocky ridge on your L after the glacial section below the Rognon.
Don't stick too closely to this rocky ridge as you head down as it ends in cliffs.
Instead head down and R slightly to rejoin the Rognons Glacier.
