Vysokii ("High") volcano looking northwest. This volcano appears to be the northernmost Holocene vent of the Eastern volcanic belt - frontal, subduction related volcanic zone of Kamchatka. Located farther north enormous Kliuchevskoi volcanic group is shifted westward and likely has a more complicated origin related to the evolution of the Kamchatka-Aleutian corner (the junction of Kamchatka and Aleutian arcs). Vysokii volcano has been active from the beginning of Holocene till at least 2000 ¹⁴C years BP, when it produced the lava flow seen at this photo. The lava flow is overlain by SH₂ (1000 ¹⁴C years BP) and SH₃ (1400 ¹⁴C years BP) marker ashes from Shiveluch volcano, OP ash (1500 ¹⁴C years BP) from Baranii Amphitheater crater at the foot of Opala volcano, and by KS₁ marker ash from Ksudach.
