Thanks - but I was hoping for a precise location. From the altitude, and its approximate direction from P40, I suspect that it is in one of the shakeholes in the fault at the head of the Pas de l'Œille. If so, which one?

Thanks -  that's very useful. It looks as if the entrance is on the fault, and about 50 metres from the main summit path. I must have walked past it twenty times...

In the event that someone might find it useful, the location of Gouffre Bob-Vouay, together with the other top entrances to the Réseau de la Dent de Crolles may be found here.

The Bob-Vouay is 180 metres from the summit of Dent de Crolles, and 56 metres below it.
