Ice retreat and the emergence of the UK

 SciA nice visualisation shared in Science.

To chart the movements of this ancient ice sheet, geologists assembled scattered clues from the shape of the landscape—features of which were carved by massive glaciers—as well as debris dumped by the ice sheet. For example, researchers pinpointed and dated the edge of the ice sheet by recognizing the hilly terrain made of mud, gravel, and rocks left behind by the retreating ice. Radiocarbon dating of animal remains such as seashells found in these hills revealed when the ice sheet departed from various locations.

Over the past few years, a group of about 40 scientists amassed these data to refine the history of what’s known as the British-Irish Ice Sheet.

It shows the melting and retreating ice which at one point covered the British Isles.

Worth reading the full article and watching the visualisation unfold.

The path more travelled

I'm currently reading Nicholas Crane's new book on the history of Britain's footpaths: how they came about originally following the drowning of Doggerland , and were then refined by successive waves of change: horses, the Roman invasion etc. It's a dense and scholarly work, with plenty of points of interest and relevance to geographers exploring the connections between people and the landscape. He's taking his book on the road in a series of talks, with three confirmed so far. Here's the description for his talk at Stanford's book shop at the end of the month . He's also speaking in Exeter and Stamford. Walking is a cornerstone of British identity and the most popular form of exercise in the UK. But how much do we know about the paths that we walk? What is their history? Why do they follow the routes that they do? Are they permanent? Can we designate more of them?​ The Path More Travelled is a coast-to-coast history of footpaths from the stone age paths...
