South Vega VN50229555 Alt. 255m  Length 120m Depth 35m

A 5m pitch drops onto rubble. The second pitch in a rift can be laddered between boulders or through a tight slot and is a 14m drop into a small chamber. The exit is through a small hole in the left hand wall. This emits a draught through a short series of 1m diameter tubes ending at a sloping 8m pitch into a grand chamber which is directly under 460. The base of the slope chokes while up the slope leads to a tight 12m pitch (dropped to a calcite choke) and a well decorated rift about 3m wide, choked at the end. The draught is lost.
