Hi,
No idea, can't remember. Plus I'm not likely to ever be there again, and I've given up mapping.
Do with it as you wish I guess.

If this is not the water you refer to, please give me a link to the object.
And I'm not new, I like anonymity and privacy, had my main account for 5 or 6 years.

It's in the bottom of the quarry, it's actually quite a bit large than I've marked looking at my photo again. It's a permanent feature
