Hmmm... I've changed to the location you cited.
The map in the paper highlights the entire north facing beach front.
The text indicates both a low lying area often covered by the sea at high tide and a higher area. My guess would be the modern road is well above the tide mark. So the burials could be both near the modern road, and then down to the waterfront.
Something is not right. This message is just to keep things from messing up down the road
