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.
Follow Nüllisch Grat ridge form slope nº9 till the slope corner, you are almost the the ridge level from there go to the top of the ridge and enjoy the views from Leidbach valley and Leidbachhorn standing on the left.
Ride down to the creek at the end you will have to follow the creek line till Leidbachalp (1793m), few houses remain from the town just before the tree line.
Keep riding down the creek till you will find few farms and a trail which you can follow to get bach to slope nº10 and ride down to Rinerhorn base station. Just be aware of the snowconditions at lower altitude, which will be the key to succes through this backcountry route.
