312 Cueva del Mazo
South Vega VN52249575 Alt. 227m  Length 230+m Depth 15+m

A small cave which carries a tiny stream through the limestone knoll at the bottom of La Vega.

A tight rift intersects a low stream passage. The remainder is hands-and-knees or flat out crawling on a bed of black sandstone. The passage becomes too tight on a corner, although this might be hammered out. The cave should join with site 368. A couple of side passages on the right are fairly grotty with sloppy mud and dangling roots.
