Upper Flood Swallet which was originally known as Blackmoor Flood Swallet, is an exceptionally well-decorated cave near Charterhouse, in the carboniferous limestone of the Mendip Hills, in Somerset, England . The cave is part of the Cheddar Complex SSSI.

The entrance was revealed in the Great Flood of 1968,[3] giving the cave its name.[4] It was dug consistently since then with breakthroughs occurring in 1971, 1972, 1985 and 2006.[1]

As of September 2008 it is over 3.5 km in length and around 125 m deep.[5]

The 2006 breakthrough

In September 2006 cavers squeezed through an excavated boulder choke into new passage. In a series of three digging trips they discovered 1.2 km of well decorated cave.[6]
