This cache and others along the Pennine Way are part of a Multi-Cache trail that have been set up by the Yorkshire Dales National Park Authority and Natural England with kind permission of the landowners.
This cache is part of a longer series of Caches, located along the Yorkshire Dales section of the Pennine Way Footpath. There are 10 caches in total along the trail (8 traditional caches and 2 finale puzzle caches). The two finale caches need a combination code to access them. The only way to gain the combination for the final two puzzle caches is to find all of the other 8 traditional caches along the trail. Inside each cache will be a ‘cache code’ consisting of a word and a number. You must obtain these to open either one of the final two caches. The caches are as follows:
cave and karst (GC1P2JX)
cistercian miners (GC1P2P3)
sinkhole stash (GC1P2PT)
hill of the winds (GC1P3F6)
jackdaw hideout (GC1P2PT)
bridge over troubled water (GC1P2RK)
devils causeway (GC1P2R6)
peat and turbary (GC1PPAB)
final caches choose from either:
malham finale (GC1P3D4) or hawes finale (GC1PPAA)
Once the final caches have been opened follow the instructions to obtain your treasure!
Note: The final two caches have been designed, so they can be reached from either direction of the Pennine Way. You only need to visit one of the final caches.
Churnmilk Hole
This cache is located in one of the many sinkholes located in the Yorkshire Dales National Park.. A sinkhole, also known as a sink, shake hole, swallow hole, swallet, doline or cenote, is a natural depression or hole in the surface topography caused by the removal of soil or bedrock, often both, by water. Sinkholes may vary in size from less than a meter to several hundred meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms.
They may be formed gradually or suddenly, and are found worldwide. Sinkholes are common where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by circulating ground water. As the rock dissolves, spaces and caverns develop underground. These sinkholes can be dramatic because the surface land usually stays intact until there is not enough support. Then a sudden collapse of the land surface can occur.
