Here’s the historical context given by James on Flickr.
9,600BC (approximately) some of the first Homo Sapiens come to the most western peninsula of Europe, which will one day become an island, Britain.
During the last ice age there had been several changes between glacier advance and retreat. Now the ice is beginning to melt and in time it will have dramatic changes to coastlines.
For the time being hunter gathers follow the mammoth and reindeer who can still travel across dry land to this part of Europe.
