Looking up, he could see that the shaft divided behind a curtain. Later in the year he entered Jib Tunnel, and realised that this was the parallel shaft that he had seen, and that a man could be lowered directly to the floor of the Main Chamber from its lip. The following year, he set up a series of jibs and pulleys, and was lowered in a boatswain's chair, becoming the second person to reach the Main Chamber. Jib Tunnel was used for explorations of the system until 1921, when the current system of lowering the winch from a gantry positioned across the corner of the Main Shaft was developed.

Lateral Shaft, a direct descent into Gaping Gill Main Chamber which is a popular caving route, and has had considerable significance in the history of the exploration of Gaping Gill. It lies within the designated Ingleborough

Professor McKenny Hughes reported that the entrance was blocked with glacial fill until a flood in 1872, when it got washed out. He wriggled round the large boulder and reached the shaft which he estimated as being in excess of 90 metres (300 ft) deep. In 1895 Edward
Calvert, of the
