Località

160 metres N of the ruins of the masia of Casa Nova. From here a small path must be followed in a N direction along the ridge line. At first it is overgrown and somewhat faint. After 160 metres it passes within barely 2 metres of the mouth of the pit, which lies to the left of the path in the direction of travel.

On the upper part of the left slope of the Fondo de les Llenties, not far from the well-known Avenc de Can Ramonet.

Descrizione

Morfologia

A 12-metre shaft of oval section and just over one metre wide along most of its course. 2 metres above its base a small window opens that connects with a short inclined conduit and gives access to a small 4-metre pit, at the bottom of which the progression remains blocked. At the upper part of this pit it continues via a narrow chimney, which has been ascended for 6 metres until the narrowness prevents passage.

Progressione

At the bottom of the 4-metre pit the progression remains blocked. At the upper part of this pit it continues via a narrow chimney, which has been ascended for 6 metres until the narrowness prevents passage.

Storia

Cavity discovered in 2005 by Àlex Arbonès (SE-CE Sitges) and Yago Marzoa, who were prospecting the area of Casa Nova and saw what appeared to be the mouth of a pit half covered by blocks; the mouth was then cleared and they descended about 4 metres of the first shaft, but the cavity remained completely filled with sediments.

Some years passed without returning, and it was not until around 2009 that members of SE-CE Sitges (Marc Arbonès, Miquel Muntanyola and Rafa Fraguas) together with other volunteer companions began removing stones, blocks and earth, hauling it all up with a bucket and the help of a tripod and a pulley.

The Sitges caving group disbanded but they kept going to the cavity to remove sediments with the help of some members of GE Talaia de Vilanova i la Geltrú (Jaume Mirabent and Mireia Henández) until 2018, when they reached 14 metres of depth.

Finally, on 1 May 2019 Rafa Fraguas returned accompanied by Josep Guarro and they made the survey.
