One of the systems that we eventually located this past weekend was beneath a plateau; a multi-level cavern that has been hollowed out by the water. The uppermost level is dry. There is a middle level; floored by great banks of mud and at times, pools of water. There is also a lower level that is totally submersed. By way of digging and hammer and chisel, local cave divers had found their way through from a spectacular karst window in glistining white marble to a deep pool in a nearby water body.
In the accompanying picture I am in the dry upper level. It is very tomb-like, the air is still and silent and my passage stirred up dust that left me hacking and wondering what it was that I might be breathing in.
It is necessary to pick your way quite carefully through this upper level as the rocks do not appear all that stable. In several places there are pits that connect to the middle level and it was by way of these shafts that I conducted my explorations.
