In the open air on the plateau of the Dent de Crolles in the Chartreuse massif, the entrance shaft to this crossing (called the P40), offers an unusual route through the rock.

Objective? To descend the P40 located at 1935 meters above sea level and follow the route to the Trou du Glaz, about 300 metres below.

13 wells intersected by meanders allow this junction, first made in 1946.
