Wookey Hole Caves then passes through major cave systems such as Swildon's Hole, Eastwater Cavern and St Cuthbert's Swallet, around Priddy, but 95% is water that has percolated directly into the limestone. The southern slopes of the Mendip Hills largely follow the flanks of an anticline, a fold in the rock that is convex upwards and has its oldest beds at its core.

The outer slopes are mainly of Carboniferous Limestone, with Devonian age Old Red Sandstone exposed
Pindai Caves Pindai Caves The Pindai Caves of New Caledonia are an archaeological and palaeontological site important for the study of prehistoric human settlement as well as of the Holocene fauna of the island. The Pindai area has been occupied by humans for varying periods over the last 2,800 years. The site comprises six caves, in coral limestone upraised about , at the seaward tip of the Népoui Peninsula on the north-west coast of Grande Terre, about north-west of Noumea. Two of the caves have easy walk-in access; they contain the richest cultural material and the fewest fossils. The other four caves
