   Walk-in sized entrance gently slopes down and bends to the right where it stays wide, but height reduces to stooped walking then crawling. A 2nd entrance crawling / body sized can be seen up the next gentle leaf litter slope letting light in (#5373) creating a small through trip to an adjacent doline / shakehole nearer the derelict barn.
    A void on the right-hand wall (woodland side) in the stoop / crawl was partially blocked by fallen rock. This was opened up by excavating the sandstone bedding layer roof and the sandy floor, creating a body sized tube into a void beyond. The route drops vertically down over mudstone, but can be free climbed with the aid of a rope. Approximately 4m down the limestone is re-intersected. A step is encountered and a window opens out onto the top of a column of rock with a rift passage trending perpendicular to the main passage above. After climbing down 2m from the step, to the base of the rift, a rock and boulder strewn slope trends downwards towards the end of the cave where the water sinks to the far left corner, creating a very tiny streamway continuing in the direction of the rift passage. Above is an aven with a hole approximately 30cm diameter above where a small trickle of water dripps through the hole. Slightly back from the end of the cave, on the right hand wall (looking inwards) is a small inlet. The inlet is approximately 1-1.5m above the floor level. There is no apparent ways on. The floor at the end has fine gravels in it and water appears to flow away in a small trickle of a stream rather than disappear through boulders in the floor. [Jess Eades, Martyn Grayson]
