Some years ago I came across a reference to a stream or streams sinking somewhere around Clee Hill with a short resurgence cave approximately 1 km away. However, I can't track down the reference anywhere. Can anyone help?

I presume you don't mean Foxholes/Oreton stuff do you as they're 4km from Clee Hill?

There is also a narrow band of Oreton Limestone about a kilometer to the south of the hill which is overlain by the Cornbrook Sandstone, so in fact there's probably a square km or two of limestone there. That sounds like your area?

Thanks all, very helpful. But unfortunately, not very encouraging!
