Area position

Updated 30th April 2013

Just to the right of the entrance is a sink taking flood overflow from site 3800. A 2.5 by 1.5m entrance enters a 4m stoop to a low chamber with a 5m slope down to a deep sump pool. It possibly connects with site 0103, Cueva de Espada. To the left, up a short slope, a sandy choke was dug into at Easter 2013 into a small chamber with no obvious way on.

After a surface survey, the position was changed from 30T 451101 4800931; ETRS89: 30T 450999 4800722 to that shown above.
