did a search for Stenness and when I zoomed in found Maeshowe and the Standing Stones Hotel. Or not - the map is centred on the Hall of Ireland and the sites ain't even in the area shown, the A964 runs down the image rather than tha A965 across. Even the search on Maes Howe has the same result. Looks like there was cloud over the Heart of Neolithic Orkney on that day, so no detail.
