The compound 2156-m-high Kambalny (left center) and 1812-m-high Koshelev (far right) stratovolcanoes rise SW above the azure waters of Kurile Lake caldera, one of the scenic highlights of the Kamchatka Peninsula. Kambalny is the southernmost large stratovolcano on Kamchatka and Koshelev is its southernmost historically active volcano. Both volcanoes have produced late-stage, very recent lava flows from flank vents on complex older structures. The small island in Kurile Lake caldera is the "Heart of Alaid," a rhyolitic lava dome.

The compound stratovolcanoes of Kambalny (left) and Koshelev (right), rise beyond the SW shore of scenic Kurile Lake caldera at the southern tip of Kamchatka. Kurile Lake caldera formed in two stages, the first about 41,500 radiocarbon years ago and the second about 8000 years ago during one of Kamchatka's largest Holocene eruptions. The small island (right center) is the "Heart of Alaid," a rhyolitic lava dome. The conical peak on the distant horizon at right center is Alaid stratovolcano, the northernmost of the Kuril Islands.

The elongated Koshelev stratovolcano (upper right), the southernmost historically active volcano on the Kamchatka Peninsula, rises SW of the Kurile Lake caldera. Koshelev is a complex group of four stratovolcanoes constructed along an E-W line over a Pleistocene shield volcano. The central and highest peak is the youngest. The only historical activity of Koshelev was an explosive eruption at the end of the 17th century. Alaid, the northernmost volcano of the Kuril Islands, is the conical peak on the left horizon.
