According on the checks made by the PGHM on last recorded positions of their mobiles, it's likely they've abseiled back to the la Bérarde side. What I've heard is that the last call they made home was done Monday, to tell they were doing the abseils, but they didn't specify their position. Then nothing.
The entire area is avalanche city now. They're very experienced, well equipped and they know the Ecrins well, let's hope they will made out of it.
