Località

From the small village of Adons, we will follow the signposted path, first with signs and then with cairns, which heads to the Pas del Portús; this route is done calmly in 1.3 hours. Once at the cairn that indicates the entrance to the Pas del Portús X:320883, Y:4687283; Z:1694, we will continue along the ridge in a NW direction, where we will find several quite spectacular dolines. The graller del Portús is located 300 metres from the Pas.

Descrizione

Morfologia

The 8x5-metre entrance opens at the bottom of a doline 18 metres in diameter and 6 deep. The shaft descends 25 metres to an inclined platform that meets a parallel spindle, which connects at various points with the initial shaft. From the ledge a 10-metre shaft places us on an inclined floor of 9x2 metres.

Progressione

On the West side we find some parabolt anchors with plates to install the rope (data from 2010).

Altri dettagli

At certain times of the year, both on the platform at -28 metres and at the final base, a large quantity of snow accumulates. The inclined floor of 9x2 metres has a large quantity of jackdaw guano.

Storia

Known since ancient times by the local people, legend has it that during a fight between two rams, they pushed the woman who was looking after them and she fell into the graller. They say that the ring she was wearing appeared at the Font de Rivert.....(how many times will we have heard a similar story in other places).

The first exploration of which there is a record was carried out by the ERE of the CEC on 4 January 1966, after having had to pay a symbolic wage to a man from Abella d'Adons to accompany them to the entrance of the cavity.

In January 2021 members of the SAM de Tremp explore a side window located in the wall of the shaft, but this ends after a few metres.
