Updated 3rd November 2021

   First looked at in 1976, the caves have been explored by the F.C.M.E.. The original notes described a wet weather resurgence, still going but more suitable clothing needed and that other caves nearby needed pushing.

   The sites have no description in reference BV, just a survey in some cases:

• Site 16: Cueva Cagulia no survey, no length.
• Site 17: S. Cubillo 1 no survey, no length
• Site 18: not named, survey, length 30m
• Site 19: S. Cubillo 3, survey, length 60m

   The sketch surveys in L76 should "agree" with the BV surveys in some cases. Not all the sites noted in 1976 have been documented in BV.

   In November / December 2015 water tracing from Cueva Orillón was found not to emerge in this area. Detectors were placed in one of these resurgences (Surgencia Cubillo 3, that the AEC Lobetum catalogue as site 1) and a resurgence futher to the north catalogued by the Cuencans as site 5. The Surgencia Cubillo 3 has been GPS'd at 30T 0456164 4793211.

   With the area map in the BV (the AEC Lobetum catalogue) it should be possible to separate out the caves here and give at least an approximate grid reference.
