News from Davide Corengia Gruppo Grotte Milano

Abstract by Annalisa Basili   Translated by Claudia Rossetti

The cave 1661 in Grigna ( so called “Abisso Speleo Salmonato”) had been explored in october up to a well with departure in a bottleneck to be enlarged, from where was possible to see a following vertical. Once furnished with the necessary equipment to dig out, Davide Corengia, Fosco Ratt and Andrea Maconi restarted exploring. After having widened, in about one hour and half of work, the narrow passage on the well and the window, that gives access to this new zone, they begin the exploration: a first P15, a following P10, two jumps and a further well. The place is getting wider below us; we are in a big fracture 25 meter high.

Here the cave starts to become wet. To the base a landslide, a new jump (P20) and it is needed to secure the well’s start (instable rocks of 20-25 kg). At the bottom of the well (about 25-30 meter deep), a window shows an enormous ambient. It is getting late, the drill is unloaded… we have to come back, but now the explored well reach -100 meter and we think 200 meter extension…there are still many things to see and the well is waiting to be explored..
