Nice one ! Do you have photos of the opened bergschrund on glacier de la tour de bousine ?
Unfortunately not. But to be more specific, there was a crevasse to get in and to get off the glacer, both passages still possible at the narrowest point, but considering we were late in the morning and that the rest of the snow was melted, we were quite cautious. To the summit of Boussine coming from Combin, no other way but the W side.
