Mendipshire How many Swallow Holes

Interesting to note when driving about the general area that there are so many apparent swallets in the fields, but choked up and grass covered.

Whilst I am no expert I suspect that the known swallets are just a small fraction of the potential total.

A lot of those "swallets" are actually mines.

The gruffy field on the right at the Miners arms crossroads is a classic example. All the depressions are very old mine shafts t'owd man used to dig down and throw the spoil around the top in a circle. once he had gone as deep as he could (20' or so) he would start a new one next to it. Net result is a field full of circular depressions.

You can see the same at Charterhouse in the field above GB (Largest chamber in Britain  ;) ) and also along side velvet bottom on the East side (above Stainsby's shaft)

Any real swallet worth a look has been dug to death  :(

although there are a few large depressions near Lamb Leer that might be worth a look ( there is a line of them from Swallet Farm across the field towards St lukes, It may be a geological feature though (Neptunian dyke, or something))

Thanks Les.
Actually it was the area near the Miners I was thinking of in particular.
I had wondered why a cave area like this had so many apparently undisturbed swallets - but with your explanation it all makes sense now. Thanks.
What were they mining? Lime or lead?

Re: bomb craters...
Actually the high ground between Manor Farm to Tynings and Burrington to the north (Blackdown?) may have few bomb-craters, this was the 'decoy Bristol' in WW2.

This paper:

Stanton,W.I., 1986. Archaeological Notes - Natural sinkholes affecting the Priddy Circles. Proc. U. Bristol Spel. Soc., 17(3), pp 355-358.

discusses the concept that some natural sinkholes have been misidentified as mine shafts.

There are certainly bomb craters on Blackdown. I think there are eyewitness accounts of them being "formed" in some of the UBSS logbooks.

For more on digging, and why swallow holes are generally not very promising, check out a superb article by Dr. Stanton, from Studies in Speleology, Vol. IV, September 1983, 77: titled "Digging for Mendip Caves".

Lead and/or associated silver (But mostly lead, I seem to recall that the silver content of the lead was less than 2% (but I could be wrong (again)))  ;)

I think it has been said and repeated many times,
that there were more than a thousand swallow holes on Mendip
before man started messing with them, miners / farmers / landowners etc.

Probably most swallow holes only take noticeable volumes of water in fairly extreme conditions. :cry:
