Réseau de la Dent de Crolles

Gouffre Pulpite

Northing: 45.31407° Easting: 5.85586° Altitude: 1,901 m

How to find it

Follow the GR9 from the Col du Coq past the Trou du Glaz onto the plateau above. At the signposted junction follow the path up towards the summit. After about 350 metres there is an obvious spoil heap 40 metres on the left, which marks the location. Note that some sources on the web give the altitude as 1,790 metres - this is incorrect.

Further information

Having been identified as a potential entrance from below, Gouffre Pulpite was dug open in 2010. Details of the cave are not readily available. It is short, but is flood prone so should be avoided in wet weather and snow melt. It has about 150 m of passage, including 20 m of restricted passage (the Tortue Ninja), between the entrance shaft and the main feature which is a 145 metre shaft dropped in three stages - 85 m, 20 m, and 40 m, the Puits du Lac. This lands into the main passage in Trou du Glaz below the Lantern shafts. From here, it is possible to exit through Trou du Glaz (4 to 5 hours) by ascending the permanently rigged Puits de l'Ogive into the Trou du Glaz upper story, or join one of the standard through trips from Trou du Glaz. All the pitches have been fixed with pull-through chains and traverse ropes. The Pulpite - Glaz route is used for commercial caving.

It is worth noting that that there is a complex of passages above the Puits du Lac shafts, with at least one connection to the Grotte du Guiers Mort. These passages, and the story of the connection to the surface, are described in an article by Olivier Dutel in Scialet 39 (2010), pp. 94-98 (copy available on bona fide request).
