In October I visited a few of the magical places so beautifully compiled in the #WeirdWalk book.
The exact locations of the ancient megaliths and geological wonders are given in Ordnance Survey National Grid (#OSGB) coordinates, a British system of geographic grid references I had not previously heard of.
Locations are noted as two letters representing squares in nested grids and numerical 'eastings' and 'northings' distances from the southwestern most corner of each square.

Yesterday's #POTD #PictureOfTheDay from Geograph was erronously listed as the island of Barra. It is actually Vatersay/Bhatarsaigh

Note that the Ordnance Survey, whose mapping is used, uses the Scottish Gaelic names for locations in preference to English

"Port Deas an Uidhe"

Also this statement seems wrong:

""Wilmott worries that these maps, now dominant, lack information that more traditional maps like Britain’s Ordnance Survey (OS) still have: “An OS map shows you where a stile is for horses; I’m not sure Google Maps even knows what a stile is. ""

I've never seen a horse stile marked on #OSGB mass market topo maps. OTOH I do know a map provider who does have that sort of information: https://overpass-turbo.eu/s/1yJS
