Depth: 1148m
Surveyed length: >6111m
Entrance altitude: 1652m
Entrance coordinates: 4*55'06"; 43*14'04"
Location
On the Xitu del Ario, N. of Gustuteru, Picos de Cornion (western massif).
Access
Starting from Los Lagos (reached by road from
Covadonga), follow the trail from Lago Ercina to the Ario refugio. The
cave entrance is on the right of the path, 100m before the orientation table
at the Xitu viewpoint (which in turn is about 500m before the Ario
refugio).
Notes
The cave is formed on the Montaña
limestone, (upper carboniferous). The main drainage has been dye traced
to fuente Culiembro in the Cares gorge (alt. ~350m), with two smaller
(probable) drainages to the fuente de la Canal de Trea and the fuente de la
Canal de la ria de las Parvulas. The cave was explored by Oxford University
Cave Club between 1979 and 1985. Two new entrances were added in 1985;
pozu de la Cistra and pozu los Caracoles (both lower than the Xitu
entrance). The cave ends in a sump.
Survey: surveyed by OUCC to BCRA grade 5b.
