The story
About 450,000 years ago a huge lake held back by ice spilled over the chalk ridge that joined England to France. It started the split that, over a long time, made Britain an island. 33.5 km is the width of the water today, not a route anyone ran. Source: Gupta et al. 2017, Nature Communications.
