Ridge and trough/Dorsale et talweg

Good day yesterday, we left the ridge.
Today, we are reaching a trough, that generates squalls and all kind of nasty winds...
Anyway, we keep progressing.

Bonne journee hier, on a quitte cette dorsale.
Aujourd'hui, on atteind un talweg, qui nous genere des grains et du vent a la con.
Ca fait rien, on continue a progresser!
