Jib Tunnel (Dihedral)

Location
Grid Reference: SD 7510 7270

Altitude: 399 m

The entrance is behind a large boulder in the true right hand bank of Fell Beck, just upstream of Gaping Gill itself.

Description
Jib Tunnel offers an excellent route into the main chamber via Lateral Shaft, giving views across the main shaft. Two 60m ropes are required (or 104m ladder and 110m lifeline).

A P-bolted traverse in the tunnel leads to a Y-hang across the top of Lateral Shaft. Four in situ deviations keep the rope out of most of the water. The rope lands on the end of a large ledge. A bolted traverse with in situ hangers (not P bolts) ends in a P bolt (and the end of the first 60m rope).

A descent from here reaches an entertaining in situ deviation which can be made easier by using your own longer sling. Two single P bolt rebelays allow a free hanging descent from the roof of the main chamber.

Access
Permission for access should be obtained from the Ingleborough Estate Office

History
Discovered in 1872. First descended in 1896 by the YRC.
