The man who discovered the 'abyss of time'
In the 1700s, the geologist James Hutton identified a formation of rocks that would transform how we think about time.
In the first of three films about "deep time", journalist and author Richard Fisher traces Hutton's steps to one of geology's most important locations in Scotland. He set out to find a richer view of the past, but in doing so discovers a coastline that harbours signatures of the deep future.
Richard Fisher is a senior journalist for BBC Future, and author of The Long View.
