Abstract

Surface exploration has revealed three additional
karstic streamsinks on the lower slopes of Western
Bluff All appear genetically related to Croesus
Cave, but today discharge their base flow to the
more recently evolved Tailender Cave Spring.
This is despite the fact that one streamsink lies
only 100 m from Croesus Cave. Drainage from
Blue Lake, a sinkhole pond, has been traced into
Rat Hole Cave, and the connection from that cave
to Tailender has been confirmed. Aquaduct
Swallet probably drains directly to Tailender,
345 m lower and 3.6 km distant. A major
extension has also been discovered in Rubbish
Heap Cave, source of the stream that discharges
from Lynds Cave, but from which drainage
connections to Croesus under high discharge
conditions have previously been hypothesised.
These data compound the evidence for the
existence of a major integrated karst drainage
system and a high probability of inter flow between
some of the components under high discharge
conditions. The highest level of protective
management is warranted for this very important
complex.
