In OTL, the farthest south the ice reached in Europe was close to London. All of Scandinavia was also buried in ice, giving birth to the Baltic Sea. Although some areas were buried in ice, the majority of Russia was still ice-free.
In this alternate last ice age, the ice went as far down south as Paris and as far west as London. Scandinavia remained buried in ice, but now the ice covered the Russian federal regions of Northwestern, Central, Volga, Southern, North Caucasian, the Urals and Siberia.
What kinds of differences should I expect to see in the terrain and topography of the affected areas?
