Located in Nidderdale on the border of the Yorkshire Dales National Park, Stump Cross Caverns is one of Britain’s premier show caves. Stump Cross Caverns offers a range of facilities for a great family day out, including a gift shop and tea room as well as the caves themselves. Following your excursion into the caves there is an optional twenty-minute film presentation, informing visitors of the history and development of the caverns within the local area.
The formation of Stump Cross Caverns
Stump Cross Caverns began to form 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.
Many years ago, underground streams found their way into the cracks and began to expand the cave system as more rock was worn away. Once the streams had gone from the upper levels of the valley the cave system was left behind, and the mineral structures that are present today slowly began to form as water dripped through the caverns.
