Clòt Mejan Dera Cometa de Montoliu

From the track from Bagergue to Liat, well before reaching Plan der Tor, there is the ravine called Arriu des Calhaus, coming from the lac de Montoliu. A path on 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 outcrop of ruiniform appearance of black schists, and the cavities called lower and middle are found on the west slope of this rocky outcrop. Approximate coordinates and without much precision.
