Descrizione
Morfologia
Through a small entrance one enters a single shaft 26 metres deep, bell-shaped and with a ledge at 17 metres from its start. Below it, the rest of the shaft has a greater volume.
Concrezioni
A fairly important lithogenic process has developed.
Storia
The discovery and first exploration was carried out by J.Montoriol and F.Vicens, of the GES-CMB, on 26 January 1949.
We have always thought that there was an error on the part of the first explorers when transcribing the record sheet of this cavity and that of Avenc de la Llosa and they swapped the name of one for the other. Possibly, the Marianet was the shepherd who indicated to them the one catalogued as Avenc de la Llosa and yet the one catalogued with his name has a smooth rock, like a slab, at its entrance.
