Rock star: I’ve spent 30 years making a Scotland map from pebbles

The amateur geologist told BBC Scotland News he has always had an interest in rocks.

“I always liked going along the beach kicking up stones when I was a boy, and I always had a lucky stone in my pocket,” he said.

After a work colleague at the Clyde River Purification Board presented him with some unique stones, he joined the Glasgow Amateur Geology Society.

And it was then that his idea of creating a map came about.

“I’d never seen it done, so I just started collecting area by area,” he continued.

“At that time I was travelling all over for work so I just collected as I went.

“Every rock you see on that map I went to that place and collected it.”
