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.
Mammut Pro Team Athlete Dani Arnold has set a new record time on the north face of the Grandes Jorasses.
At the end of July, the 34-year old climbed the Walker Spur (4,208 meters) in the Mont Blanc massif on the Cassin route in 2 hours and 4 minutes.
He now holds speed records on two out of the three legendary north faces in the Alps. For the third summer in a row, Dani has been focusing on the Grand Jorasses north face project.
In 2016 and 2017, weather conditions made any attempt impossible.
Then, on July 27, 2018, it all finally came together: Dani caught a good weather window and good conditions to set a new record.
The world-class alpinist conquered the north face with a height of over 1200m on the Cassin route in a sensational 2 hours and 4 minutes and was overwhelmed. Full blog post: https://www.mammut.com/stories/dani-arnold-speed-record-on-grandes-jorasses-north-face/
