Approaching the cave from the North West, descend the steep 10m high karst slope, to a 2m x 3m entrance shaft at right hand edge (viewed downslope) of the rock exposure.


2m x 3m entrance shaft at right hand edge (viewed downslope) of the rock exposure


The entrance shaft has two old spits, placed low down on the north wall. However, the southern wall provides a natural thread and large rock boss to give a sloping 5m descent to a boulder wedged across the rift shaped passage. A single bolt rebelay at the wedged boulder gives a free hanging descent of 13m to a sloping gravel floor.
Upwards from the gravel slope a 1.5m wide rift has not been followed but appeared to curve to a drop, possibly into the main chamber below.
Down the gravel slope a large boulder (which contains an old spit in its outer face) at ground level forms the lip of the final pitch. A single bolt to the right as viewed looking down the pitch, gives a sloping descent to a rebelay after 10m, followed by a deviation 4m below and finally landing on the chamber floor after a total 18m descent.
A chamber approximately 30m in diameter slopes from the gravel cone at the base of the pitch towards a rock rim at its downslope edge. Beyond this rock rim extends to a wide down dip bedding passage, a clear route is not easily identifiable but small canyons in the bedding floor may provide a way on.
No draught was detected, although the air was generally fresh and cold.
