Usually in seeing a sinkhole it suggests that the surface is being nibbled away from beneath. Not surprisingly there are tunnels under this farmer’s field. At the bottom of this sinkhole there is a barrel in the hole.
This feature beside which JC is standing sits about 50 meters from our newly discovered cave – Wasteland Waterway. All along the front of this buried ridge – not easily seen from a distance there are numerous sinkholes, several of which are taking streams from a marshy area nearby. On second thought, it might also be a buried fissure, it’s hard to tell as there is so much overburden.
JC and I are still trying to understand the local geology. We are optimistic that the cave we have found connects several of these sinks.
In about two or three weeks we are returning to follow the passage for a greater distance. We think we are on to something that could be substantial if it doesn’t sump. Then again XS Wire also looked a bit like this (but smaller) and it sumped pretty quick.
Seeing that the tunnel beyond where we had crawled begins meandering it might suggest a lot of open bedding plane space. The layer in which the passage has formed is very much pitted and corroded, the layer above the tunnel seems to erode much more smoothly. There is evidence of flooding up beyond the tunnel entrance so I’d imagine that this is not the place to be on a rainy day.
