This is more in keeping with the spirit of the quiz – “What lies here?”
Will try this immediately. Your other suggestions, while worthy of a guess are possibly a little too simplistic. I am pretty sure the co-ordinates are correct, which rules out some of your other suggestions. I only say this because another “contestant” says he has a correct answer and it has been checked.
My own gut feeling is that there is something buried in the ice here, or lying under the ice, in the water – hence I will try variations on “Williams”, “bulldozer” etc.
Once again, thanks for the advice
