A surface-network cavity with several 3 m pits, A 4 m chimney and very narrow crawls, whose access has been completed by an artificial entrance.
Descrizione
Morfologia
The one-square-metre entrance (P 3) is followed by an inclined plane in A joint. We follow A meander with A vault in scree. About ten metres from the entrance on the right, A flat-out crawl gives access to A small chamber from which A new, very tight joint starts, with A slight draught. At the top of the P3, A 4-metre chimney with an exit in A constriction leads us into A hyper-narrow crawl (0.50 x 0.30) with A cooling draught. The artificial entrance (P 3) drops at the crossing of three galleries. After 5 metres, an SSW gallery is choked. The third gallery opens into A small chamber ending in A choke with the possibility of digging it open. This cavity resembles A surface network.
Progressione
Continuing the progression in the main gallery, we meet A P 3 with A draught and possibilities of A continuation. Given the uninviting dimensions of the passage, we decided to create an artificial entrance. To do this we placed A transmitter in the chimney and took bearings on the surface. We took A sighting in the gallery and estimated the length. The surface plotting being done, we dig the new entrance. The most obvious continuation would be at the bottom of the P 3 in line with the chimney.
