IntroductionThe northern flank of Smirnov is still partly intact, while the southern side has been eroded by glaciers, where its oldest rocks are now exposed.
Inside a wide glacial valley on the SE side there is a cinder cone and an associated 4 km long lava flow. Another pyroclastic cone is located at the base of the valley near the end of the lava flow.
2 fresh-looking lava domes less than 10,000 years old are found in a glacial valley on the north side. On the NW side Smirnov overlies the older edifice of andesitic-to-dacitic Rurui volcano. Rurui volcano still has an active fumarole field on its western flank and might not be completely extinct.
