We continued work at the top of the rift/pot. What appeared solid is not, and there are a lot of boulders, cobbles in a matrix of finer sediment above the opening. Managed to bring quite a bit of this down and now have a small chamber about 1m x 1m x 1m although not quite big enough to turn around in safely. The downside of this work is that a good quantity of debris has fallen into the rift/pot so there is a considerable amount of clearing to be done. We are puzzled by this passage development we did expect to see another wall to the rift – are we heading into a chamber? Only digging will reveal what lies ahead.
