If it was on the surface, yes. But there is a lot of salt underneath
Cheshire, that has not leached in millions of years. I could very
easily believe that many such deposits are mixtures of sand and salt,
and that there are places where salty sand is an accessible mineral
(and not near a current seashore).


Thinking of which, a few years ago, we went to a hilltop village in
Provence, called Les Baux. It's thousands of feet above sea level and the
pathways and walls are studded here and there with limpet shells - it was
fascinating!
