CO-ORDINATES: 30T X:0364417 Y: 4789200
ALTITUDE: 455
LENGTH: 500m (excluding beyond sump 1)
DEPTH: -37(including sump 2)


LOCATION:

Follow the canal for 1km down from La Cueva del Agua. On the sharp bend in the canal (after walking through a tunnel on planks supported above the water) one finds a sluice gate and a cave entrance.


ENTRANCE:

The entrance has been modified by blasting and lies on the fault. A stream issues from the cave and joins the canal.

DESCRIPTION:

The passage has been enlarged by blasting for the first 200m and the stream is carried by a man-made canal. This has re-directed the stream from its previous route which was down a steep fault-guided rift that we did not explore.

Shortly inside the entrance the first sump is met, dived to air bell after 35m.

A further 100m of walking and climbing leads, via a series of deep pools, to a sump, very large and clear.

Possible continuations include steep upward slopes (ed. 2011 - climbed in 1970's by Colin Boothroyd - no leads) and a draughting but impassably tight hole above the sump. The second (terminal) sump was dived to -55m in a descending canyon - continues down. (ed. 2012   sump tied off at approx -37m (not 55m as reported)).  

Engineers had worked extensively in the cave, penetrating as far as the sump, presumably when the canal and hydro were built.
