After persistent rain last weekend, it was not a surprise to find that the trip through Chamber 20 was wetter, the calcite cascade had water flowing down it. As suspected the sand dig was had about a metre of water at the bottom and there was still a trickle of water flowing into it, as such, it was undiggable. There were a few rocks in a vulnerable position, if a slump-in occurred they might end up at the bottom of the dig. So, these were moved and the spoil retaining wall was extended.
We were in the Hunter’s a bit earlier than usual. At least the forecast is for dry weather for the next few days, so the dig might drain. Unfortunately, it will not take much rain to refill it though.
