What caught my eye there was the apparent angle of the vein. It looks nearly horizontal. We've one like that in North Wales (Moel Ferna) but I understand it to be rare.
Is there much slate mining in the Czech Republic? It's not an area I know much about and there are only 5 mines in the database from CZ.
my orders are to sit here and watch the world go by
