Cave details
This cave is almost connected to Lost John's Cave. The Ireby Fell entrance enters a series of pitches leading to a semi-circular shaped main stream passage. Two sumps must be passed (the first can be pumped or bypassed, but the second is divers only, sorry) to enter Notts Pot. Notts Pot has entrances leading to what must be the most complex vertical maze in Britain with several choices of routes. Most routes eventually reach the sump which leads into the well decorated Notts 2 with its terminal sump, and alternative dry entrance. This almost connects with Lost John's, and will almost certainly soon become just another part of the extensive Lancaster - Easegill - Pippikin - Lost John's system. In the other direction, Ireby Fell Cavern has tighter passages connecting with the larger passageways of Rift Pot and Large Pot. Importantly, these drain in the opposite direction to the main flow, into the currently unconnected Kingsdale Master Cave, showing that future connections could provide a very extensive cave system of around 110 km.
