IntroductionThe early Holocene Otdelniy shield volcano (Masurenkov, 1980) lies east of the Savan River, across from the Pleistocene Savan volcano. The 719-m-high Otdelniy lies at the west end of a large group of late-Pleistocene to Holocene pyroclastic cones. It, along with Tundroviy and adjacent unnamed shield volcanoes, is adjacent to a large group of late-Pleistocene to Holocene basaltic pyroclastic cones located about halfway between Khodutka and Opala volcanoes. The cones and associated lava fields are located at the headwaters of the Savan and Asacha rivers, which drain to the Sea of Okhotsk and the Pacific Ocean, respectively. Three groups of late-Pleistocene to Holocene pyroclastic cones and associated lava fields are also located along a roughly 20-km-wide area between the Opala and Savan rivers, SE, south, and SW of massive Opala volcano.
