Volcanism along the elongated Maly Semiachik massif has progressively migrated to the south. The southern flank is mantled by Holocene cones and lava flows. The SE rim of a large Pleistocene caldera forms the low ridge in the background and the Pacific Ocean is visible in the distance. Photo by Dan Miller, 1990 (U.S. Geological Survey).
