Went there again today at low tide, all prepared GPS, tape etc. Thought I could remember where it was, we searched around by the piers to avail :-(
Got back home checked the first discovery pix and deduced I was searching on the wrong side of the peir :-(
I'll shall return again on the next low tide and get a good GPS fix.
I feel this is turning into a right little project :-)
Stone size is 7ft by 4ft.
