The Sedankinsky lava flow is shown here with the source and the terminal part of the flow marked with pink stars. The vent lies at about 1,600 m elevation on the south flank of Gorny Institute volcano. Based on tephrochronological dating, the eruption took place about 6,200 years ago. The flow descended the Sedanka River valley.
