Scans from “Images D’Escalades,” a collection of mountaineering pictures covering climbs in the Alps – most of them were taken by André Roch, who was both a well respected climber and avalanche expert. I could not find any specific date for when it was published, but some years listed with a few of the climbs photographed indicate that it was likely released around 1946. I’ve also attempted to translate parts of it from French, but I’m sure it’s not perfect.
L’Arête nord du Weisshorn (4505 m) est vertigineuse. Le parcours de cette crête se fait constamment au-dessus de précipices très profonds. – The northern ridge of the Weisshorn is breathtaking. The course of this ridge goes over very deep precipices.
