Porthstenack Cove? - Near Tregeseal Stone Circle

I have my doubts about this having had any mining connection, as there is nothing that I can find of the area being used as such; there is a clay working to the south, I know, and I do not see any possibility of this being a bomb crater from the 1941 bombing at Tregaseal. In view of the presence of minnows, I believe this to be an ancient water pool, as the area is quite lush and level. I will see if I can work out the geology/topography. If anyone knows to the contrary, let s hear it. What was the largest minnow that you could see? They can grow to 4 inches. Tin streaming has been worked in the area, it has to be said. Water was taken from the stream at Bostraze, to operate the mines at a the lower level, so had no need to construct a pool for supply.

The area is a natural water trap, being a large glacial depression. The oaks that once grew here eventually were lost, after the building of St Just Church, using many of the trees. Oak trunks have been found at twelve feet depth. I have seen much the same thing happening in London, where trees were removed, leaving a very wet area, the soil quickly is washed away, not having cover, and precipitation no longer being retained by the trees themselves.
