About 50m past Wade's Entrance the track to Gaping Gill Main Shaft passes between two rocky shakeholes. That on the left merely chokes after 3m, while on the right is OBJ Hole (see surface survey). The first pitch of 4m can be free climbed easily. At bottom of this the blind pot mentioned in Northern Caves as 10m deep is in fact 3m; and can be traversed over to reach the head of a 12m ladder pitch (see cross section). The final pitch, an 18m free hang, reaches a shingle choke in the floor of the rift. An oral connection can be made with the passage in Flood Entrance Pot which is only a metre or two from it (survey).
