FATMAP difficulty grade
One way to access to this line is via the top of the Corbeau's ski lift, or in case of the slope being closed, you can get there via the blue slope "Le Lac" going into the wrong side.
Won't recommend this if the slope is open as this might end up in collisions.
We will need to follow the black slope "Corbeau", then before the middle section turning into the left of the slopes.
This will be a long crossing crossing quiet easy navigation as we will need to be over a long trees section, nothing really dangerous as this won't be steep and trees help to make the line stable.
We aiming to stay higher as possible until the flat part, then we will follow a gully between trees as this will be the only access to our line.
Keep an eyes into the left part of the line as avalanches can come easily, other dangerous hazard will be present at the end of the gully with a lake, to keep it clear once the gully is done and the really is flat you will join the lake.
So be careful as mistake will bring you into the lake and area is likely to be without any peoples at all, what can kill you in case of mistake, we will stay higher than the lake into a long walking or pushing traverse in order to join back the Bosson's ski lift or getting access back to the blue slope "Le Boude".
Last hazard of this line will be the fact we are getting close a ski lift where collisions can happen, good knowledge of avalanches is needed as slow crossing for about 20 minutes will make it more risky to cross above the lake until the bottom of the ski lift.
