Zheltovsky rises across a valley NE of Iliinsky volcano. The flat shelf on the right flank is the eastern rim of a 4 x 5 km, largely buried Pleistocene caldera. The western rim of a smaller, late-Holocene caldera forms the break in slope on the left side just below the summit lava dome complex. The crater in the foreground is a NE-flank maar of Iliinsky that formed in 1901.
