Stones of the Refuge shelter at Witchcraig

Stone enthusiasts only!
There is a stone-built refuge area at the top of Witchcraig hill behind the Korean War Memorial near Linlithgow & Beecraigs country park. 
It is made up of different stone types from all over Scotland. So here is a collage of rocks along with a picture of the guide to what is what.
They are labelled A to Q, but seem to be missing A & F. Probably the little metal letters fell or were pulled off.
Here is what the refuge stone looks like from a few years ago in this other blip. Plus an extra of the guide to the stones that is a bit bigger as it's probably not readable in the collage!
Anyway, not very exciting, but 400 million years of geology can't be all bad.
