Mendip Hills lithics. Large numbers of artefacts have been found near Neolithic, Iron Age, and Bronze Age features, such as the barrows and forts around Priddy and at Dolebury Warren. The caves of Cheddar Gorge have yielded many archaeological remains, as flood waters have washed artefacts and bones into the caves and preserved them in silt. The Cheddar Man, Britain's oldest complete skeleton, was found in Gough's Cave, part of the Cheddar Complex. Within the Mendip Hills AONB, good evidence exists for 286 definite examples of round barrows, including the Priddy Nine Barrows and Ashen Hill Barrow Cemeteries. The Historic England Archive
Wookey Hole Caves as an inlier at the centre. Wookey Hole is a solutional cave mainly formed in the limestone by chemical weathering whereby naturally acidic groundwater dissolves the carbonate rocks, but it is unique in that the first part of the cave is formed in Triassic Dolomitic Conglomerate, a well-cemented fossil limestone scree representing the infill of a Triassic valley. The cave was formed under phreatic conditions i.e. below the local water table, but lowering base levels to which the subterranean drainage was flowing resulted in some passages being abandoned by the river, and there is evidence of a number of abandoned
