   A stream rises at the head of a small wooded valley below a 4m limestone cliff. The stream splits immediately inside the entrance. The left hand passage is stooping size for about 45m to a T-junction where, to the right, a tall rift passage can be followed in liquid mud, but has not been pursued. To the left the main passage continues, becoming small and partly excavated through mud walls. Some 30m from the junction, an excavated section squeezes through to a 12m high, drippy aven with a crawl through to a similar sized feature to the north. The muddy trench continues upstream for another 25m or so until more excavation is required at a sideways squeeze. "Station 0" on plastic paper  is on the northern mud wall at this point. There is a draught blowing out and no particular difficulties in scooping out the passage forward.
   In summer 2006, "30m" was added to the length beyond station 0 by removing mud from the walls. The passage continues with more work required. The new length remains unsurveyed due to the muddy conditions. "The next trip will need to survey this and continue with the mud mining". That trip occurred at Easter 2013, when there was a "huge stream exiting the cave". The passage at the end was pushed round a corner to a small pool with a cascade entering. This comes out of a rabbit-sized hole with no prospect of digging. A survey was carried out but there is something wrong with the data. The total length above is a reasonable figure.
   The Black Mud Inlet has been dug, disturbing some foul-smelling sediment. Several body lengths have been excavated and the passage continues much the same. Wearing a wetsuit is recommended.
   Just inside the entrance, straight ahead, a walking-sized route quickly leads to crawling round to the right then left past two dams. These are man-made with a water pipe. Water flows out from a narrow rift which has strange acoustics and could be enlarged.
Below the entrance, the resurging water sinks between large blocks without any immediate prospect (site 2184).
