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.
##Ascent One hundred metres after the junction for the Baños de Benasque, and just after the bridge over the brook of Lliterola, follow the right path that comes out of the woods quickly and climbs to the cabaña de Lliterola (2000 m).
Go up the valley by the left bank without any history.
In the case of the Lliterola ibonet (2460 m), the summer route is very far from the valley, but when the snow cover is good you can stay in the notch, especially on the descent.
A steep slope (35° by about a hundred metres) then leads to the overflow of the ibón de Lliterola (2730 m).
Go up to the W the vast slope, generally poorly covered with snow, long and steep enough to reach the final ridge, and follow it to the top. ##Descending Ditto, following the entire notch of the stream, playful.<br/><br/>_This Adventure has been shared under the [Creative Commons Share Alike](https://creativecommons.org/licenses/by-sa/2.5/) licence._
