The maar crater in the foreground formed during an eruption in 1901 on the NE flank of Iliinsky volcano. Light-colored tephra was deposited around the rim of the crater and cover the flanks of the volcano. At the end of the eruption lava was extruded on the floor of the 200-m-deep, 1-km-wide crater. Zheltovsky is the volcano to the left of this image.
