I've done a bit of research into Magnesian/Dolomitic Caves - somewhere there is a RIGS for the Doncaster/S Yorkshire area. I've never heard of there being any streams in Magnesian or Dolomitic Limestone, although, I think, there is a well/resurgence somewhere, which I believe is the only occurance of a cave related feature on that type of limestone coming anywhere near the water table.
However, that being said, I have a nagging thought that there was a report some years back that water was heard in one of the Maltby caves, not Herne Hill No. 1 - which is open but gated (requires Derbyshire key x 2 to open) but one of the other two, both of which have been landscaped and presumed losft behind the supermarket in question.
Thank you for that information Martin.....
The RIGS. Report took its information from available modern written sources, there is no original feild or other information gathering in that report on the Speleological potential of the region and it's limestone's. Someone had just gone around with a copy of Northern Caves guidebook and that was that.
There are many large resurgences along the edge of the limestone...
Some magnificent phreatic caves are know such as those at Cesswell Crags..... an indication of the scale of cave formation awaiting whoever might do the investigative research and focused effort required
There's at least eight stream sinks that I know of on the limestone near Doncaster, including one very large one......Where tree trunks have been observed to be sucked down.
There is a reasonable height difference and distance between the biggest of the sinks and potential resergences
There is both relic vadose as well as phreatic features to observed in the known caves.....
The flowstone formations, curtains and stalactites, found in some of our Dolomite limestone caves are quite often among some of the most spectacular and beautiful.
It would be exciting to discover and explore an active stream cave, with these indicators of what may be found along the way.......
