An interesting report, especially for those of us who know the area.
And it reveals that the potential of the enormous resurgence I photographed during a rafting trip down the Tara canyon remains untapped. I took this photo in August, after several weeks of dry weather. The resurgence is blocked with boulders, but the cliff behind it is riven by a high, vertical cleft. I would say it is several times the size of any of the resurgences in the Cares gorge in the Picos, including Culiembro, the outlet for all the caves in the Ario area and beyond.
