A wide shaft, about 4.5m deep with an oak tree in the entrance. The hole has a flat floor with a slope down to a bone-filled rift, with a rift going above but pinching out. A small inlet is possible from site 722 which is just above. No real prospect of digging. (This is a very obvious hole and must have been known previously?)
