Visoky, at the northern end of a chain of small volcanoes trending NNW from Gamchen volcano, is a small Holocene stratovolcano with a youthful-looking summit crater constructed over the east flank of the Pleistocene Bogdanovich shield volcano. Vysoky (also spelled Vysokii) lies only 4 km NE of Komarov volcano. Another small Holocene volcano lies between Komarov and Vysoky. These mark the northernmost Holocene volcanoes of the Gamchen volcanic ridge and the northernmost of the near-trench portion of the Eastern volcanic belt of Kamchatka related to subduction of the Pacific Plate. Visoky was active throughout much of the Holocene until as recently as at least about 2000 years ago, when voluminous lava flows were traveled down the volcano's flanks.
