From the long cabana walk north along the track towards the Caseton de Andara. Take the first obvious track on the left past T122 and follow it up to the level ground and spoil in front of the mine Google Earth 360950.00 4785411.00


An obvious 2m by 1m walk in adit entrance in a snow filled rift.


Walk into a junction 20m from the entrance. The right hand passage leads to an undescended pitch whilst straight ahead for 200m leads to a 40m pitch. From the bottom the right hand route has not been investigated but left past an undescended shaft leads to a 20m pitch through platforms and a further 10m pitch.    
From the bottom, to the left, over two shafts (the second followed down to a flooded level) the mined level continues to T154 (CUESTA). All the workings taking off this level are blind including the natural shaft 30m from the exit.
