Jeff and I made a recent reconnaissance in the Wasteland Waterway Cave system as we suspected that with the filling of the Blue Barrel sink, the cave passages had been blocked and so the deeper reaches of the cave system would now be sealed forever. But nature is more persistent than that and the sink had cleared itself out from beneath. On the surface there is a slight indent, but below the tunnel is perfectly clear.

I suppose this now brings to light the question as to when we are going to push the tunnel to its very furthest endpoint. We strongly suspect that beyond the ‘gulch’ and the aerofoil the tunnels get bigger again. You ask what is stopping us? It’s a long cold crawl and a tight squeeze at the end of that which makes me somewhat leery.
