Réseau de la Dent de Crolles
« on: June 04, 2021, 04:49:19 pm »
Gilbert Bohec has informed me that the Dent de Crolles system now has a thirteenth entrance - le nid de Choucas (The Jackdaw's Nest).

It is well named as it is located high in the eastern face. It was discovered from below by scaling in the Grotte Chevalier.  The photograph, taken by Gilbert from his house, has a red cross marking the new entrance. You can see the Annette and Chevalier entrances marked at the top of the grassy terrace towards the left.

I think I would have got vertigo if I had stuck my head out of there...  :o

It's always struck me as a happy quirk of nature that the other entrances are conveniently situated at the base of the cliff, rather than halfway up it.

That's geology for you - the two large phreatic passages at the eastern end have a tendency to follow the base of the Urgonien limestone which form the cliffs.

Knowing (and admiring) the French way of things I fully expect on my next visit to find a series of abseil stations installed allowing access from the cliff top.  Or a via ferrata traverse, either will do.

Shame you didn't find it Andy then it could be called Sparrow' Nest.
