Bolshaya Ipelka (Russian: Большая Ипелька) is a massive shield volcano at the southern end of the Kamchatka Peninsula in Russia's Far East region.[1] It represents the largest volcanic structure of southern Kamchatka Krai, covering an area measuring 32 km (20 mi) long and 42 km (26 mi) wide.[1][2] Bolshaya Ipelka is of Pleistocene age and formed west of the main volcanic zone in southern Kamchatka. The shield volcano is now inactive, having last erupted during the Pleistocene epoch.[1]

Bolshaya Ipelka is extensively eroded, having been dissected by deep valleys along its flanks that were formed as a result of glaciers flowing out from the summit during past glacial periods. The summit is the most severely eroded part of the original cone, which originally had a much higher elevation than its present 1,155 m (3,789 ft). By contrast, the neighbouring Opala stratovolcano has an uneroded form and is still volcanically active, having last erupted about 300 years ago.[2]
