Description

General description

BTH - 13/03/2026

It is a segment of the Three Counties System, linking the Rift Pot system to the south with Notts Pot to the north.[3] This popular cave starts with a pitch series that eventually opens out into a very large series of dry sandy passages. The entrance is a vertical concrete pipe at the bottom of a shakehole that was last shored up in 2006. The traditional route is down three pitches (Ding, Dong, and Bell), but there are several alternative routes. All may become impassable in wet weather. After many metres of rift passage is Well Pitch which accesses the main lower sandy passages known as Duke Street. At the far end of Duke Street is Whirlpool chamber where a short sump (not free-diveable) gave access to cave divers into further passages known as Ireby II.

History

The prominent depression of Ireby Fell was marked as "The Cavern" on the first (1847) issue of the Ordnance Survey maps, though the early explorers could see little justification for the name. Various digs were undertaken from 1932 onwards until in 1949 a small scar on the NW side of the shakehole gave access to a passage that reached the first pitch. Much of the cave was explored and surveyed down to the sump at the end of Duke Street. The cave entrance then became blocked in 1953 until it was reopened in 1963.
