| The largest
caves in the Cheddar catchment occur along the southern side of Blackdown,
around Charterhouse. These caves, GB Cave, Charterhouse Cave, Longwood
Swallet, Manor Farm Swallet and the recently extended Upper Flood
Swallet are classic examples of swallet caves. Relative to their
size, this group of caves, especially GB Cave, are some of the
most intensively studied in the world. All five major caves are similar
with streamways, often well decorated with stalagmites, descending
down to a sump or a choke, with up to four tiers of relict high-level
phreatic passages. The caves drain to Cheddar Risings. Above these large springs at the mouth of Cheddar Gorge there is a complex series of abandoned caves. The largest is Gough’s Cave, 2.1 km long, which intercepts the underground River Yeo, which has been followed upstream through several deep sumps.   |
 Discovered in 1898, this show cave is also one of Europe’s most important Upper Palaeolithic archaeological sites and the home of ‘Cheddar Man’, one of several skeletons found in the cave. Mitochondrial DNA from this skeleton was found to match that of a school teacher living nearby today. Several other smaller caves, Great Oones Hole, Long Hole and Gough’s Old Cave occur higher in the cliffs. Further up the gorge is Reservoir Hole, a relict cave system which once drained to Cheddar.  |
