Kambalny (left) and Koshelev (right) rise above the SW shore of Kurile Lake caldera at the southern tip of Kamchatka. The caldera formed in two stages, the first about 41,500 radiocarbon years ago and the second about 7,600 years ago during one of Kamchatka's largest Holocene eruptions. The small island (right-center) is the lava dome referred to as the "Heart of Alaid”. The peak on the distant horizon at right-center is Alaid in the Kuril Islands.
