Caratteristiche

Località

To access it, you must turn off at the roundabout giving access to the Lledoner urbanisation and follow the old road as far as the Creu d'Ordal; a little further on, just where the road turns right, a path leaves from the left-hand side which we follow until reaching the road embankment. We continue to the left until descending into the road ditch; from here we continue about 60 metres in the direction of l'Ordal, where we will find three holes behind the metal protection netting. You have to pass (we do not advise it) under the netting near where there is a small cave one metre long and, from here, taking great care not to touch the netting due to the danger of falling stones, climb diagonally to the right up to the entrance.

Descrizione

Morfologia

Cavity opened during the construction of the road. Through a narrow hole one reaches a chamber full of blocks deliberately placed by the company that built the road. On the right we find a gallery that ends at 2 metres. The chamber is about 3X3 metres; on the ceiling we observe a second entrance that also lies beneath the metal protection netting. The height of the chamber is about 3 metres. After a step of 1.40 metres we find a pit against the wall of about 2.80 metres; at this point the blocks are in precarious equilibrium. At present the vertical extent of the cavity is 6 metres (-4/+2).

Concrezioni

The facing wall is covered with calcite deposits (broccoli).

Storia

Cavity opened during the construction works of the new bypass of the N-340 road at its passage through the coll de l'Ordal; these works took place between the end of the last century and the beginning of the 21st. The first exploration was carried out on 11 May 1997 by Federico de la Vega and A. Arque of the Grup Mediterrànea while the excavation of the road was being done; they, amid the works, made a quick visit and a sketch of the cavity, which they named avenc de la Variant. In March 2009 it was visited by the GE Badalona, unaware of the previous exploration despite it having been published in the magazine Excursionisme, and they named it coveta nº 5 de la Cuneta.
