The formation of Stump Cross Caverns began millions of years

The formation of Stump Cross Caverns began millions of years ago, when the area which is now the Yorkshire Dales was covered by oceans. Sediment from the ocean floor would eventually form limestone, the basic material from which the caves are made. The caves themselves began to form as the limestone was eroded by weak acid rain, created when carbon dioxide from the atmosphere mixed with the precipitation to form carbonic acid…..fascinating nature at its best 😊
