Caves: Poole's Cavern
Limestone is slightly soluble in rainwater and, over many thousands of years, surface weathering and groundwater circulation can remove rock material by solution. In relatively hard, low-porosity limestone such as the Carboniferous Limestone, the solution process is focussed on joints and fissures. Over long periods of time, these may be enlarged into underground cave passages.
There are around 250 caves recorded in the Peak District, but most are of short extent and of limited interest for underground exploration. However, a number are much longer and a few are open to the public.

One such cave system is Poole's Cavern at Buxton. Here, visitors can view a range of interesting stalactite and stalagmite formations. This cave system shows evidence of occupation by both prehistoric animals and Bronze Age man. Romano-British people may have worshipped a water goddess in one of the chambers. Many cave entrances in Derbyshire provided shelter for early man and a number have been the subject of detailed study by archaeologists. The caves and the underground drainage system of which they form part, together with the dry valleys, sink holes and springs which are their surface expression, make a significant contribution to the limestone scenery of the 'White Peak'.
