   One of two resurgences at this level on the north side of the Vega valley, the other being Fuente de las Colmenas (363). Crawling leads to a small chamber and a duck. A calcite climb on the left bypasses this and leads to a deep pool which bends to the right and ends at a draughting 'sump'. The draught issues from a small eyehole. The passage continues under water to the right of the sump pool. An 8m awkward dive surfaces in a rift with the main way on in a parallel rift. The draughting passage continues to link with Fuente de las Colmenas. A roof level passage 60m beyond the sump draughts out strongly but only connects further up the cave.

A water trace from a sink in the Cubjia valley (near Regatón) has been started (February 2024) and is ongoing. Detectors are in Rioturto Inlet, Cueva Molino and this resurgence
