- Source: Sopka (mound)
A sopka is a monumental tumulus resembling a kurgan, referring specifically to those built by the Novgorodian sopka culture of the Early Middle Ages. The archaeological term "sopka" should not be confused with generic the Russian word "sopka" for hills and mountains or smaller elevation with rounded top and gentle slopes.
The term "sopka" was introduced by Zorian Dołęga-Chodakowski.
The Peredolian sopka is a famous example of a sopka.
