A very small entrance was enlarged to give a squeeze through to the top of a chamber with a 5m drop to the choked floor. All the walls and roof are covered with old, friable concretions and there is an ONCE beachball at the bottom. When explored, there was a good draught to start with but there was no draught at all once descended and no possible way on.
