In 10m diameter shakehole on N side, half way up easy way out of the 4m deep, flat floored depression. A small hole leads to a drop where stones fall about 2m. No draught when the temperature was 11C. To dig would need caps or snappers and only be worth it if there is a good draught in hot weather (i.e. inward).
