 The generally accepted geographical border between Europe and Asia runs along the crest of the Ural Mountains in central Russia and of the Caucasus along the southern border of Russia.Since the massive twin-peaked stratovolcano of Mount Elbrus rises just north of the crest, it is the highest summit in Europe and also the highest volcano.Some geologists, though, consider the Kuma-Manych depression as the geological border between Asia and Europe.
