Clòt Superior Dera Cometa de Montoliu

From the track from Bagergue to Liat, quite a way before reaching Plan der Tor, there is the ravine called Arriu des Calhaus, coming from the lac de Montoliu. A path to the right of the track climbs in the direction of the Pòrt d'Urets, about 300 metres before reaching the flat area at the 2200 m contour; to the right of the path there is a rocky area of ruiniform appearance made of black schists, where the cavities known as lower and middle are found on the west slope of this rocky area. Following the path, two bends further up and on the crest of a small valley bottom, the upper hollow is found. Approximate coordinates and without much precision.
