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.
