We took Rohan this time so he could film the extensions and help us with exploring the new passage with a lump hammer. After another 10m, we thankfully found a way up into larger passage, which was pleasant exploration of about 80m until we were forced to stop at a calcite blockage. We dug our way down to stream level but progress here was horrible and muddy and tight, and continued this way for at-least another 50m (Rohan and James took a look ahead). With me worrying about dehydration I headed back to drink some water and met them half way. Dave said the big stuff in this cave is really nice and worth a visit.
