A complex opening. The hole deeper into the hill has been dropped for about 10m, but there is no way on.
The opening under the outside rock wall has a constriction 2m down but floor can be seen at 4m. As there is no discernible draught, the effort of enlarging the constriction seems somewhat futile.
