1804: cave
Riaño 30T 451488 4800544 (Datum: ETRS89. Accuracy code: G) Altitude 127m

Updated 1st February 2006

An open entrance in a depression below a chicken coop. The 2m wide entrance rift drops down over boulders until the passage turns left where it is about 5m high. A few metres further on the rift closes in. It is possible to climb up in the rift to see possible continuations, but the way on is near the floor where various contortions gains a wider chamber. At the far end of this, calcite closes in again and it appeared likely in 2002 that a generator and chisel would be needed to continue.
However, the Easter 2003 excavations in site 1805 gave an aural and visual link with this cave. Both appear to be near to the supposed downstream continuation of Cueva Riaño (site 105)
