Survey of the Réseau de la Dent de Crolles
This is a Deep Zoom-style implementation of Gilbert Bohec's 2007 compilation survey of the Réseau de la Dent de Crolles. You should be able to use your mouse to zoom in and out of the image, pan round the image, and a tool bar option allows you to go into full-screen mode. If you can't, or you can't see an image, then you can download the survey as a simple image (1.7 MB).
Note that the survey does not include the five recent entrances of Gouffre Pulpite, Gouffre Bob Vouay, Maxi Méga Marmotte, le Nid de Choucas, and but an indication of where they fit in can be gleaned from a small scale survey available here (0.38 MB). The recent entrances (2022) of la Grotte des Excités, l'Entrée des Artistes, and le Balcon are all associated with Grotte des Montagnards in the eastern cliffs, and a survey is not yet available. A survey is also not yet available of the most recent entrance Gouffre du Coeur (2023).
