Thumbnail Photo (see caption)Kambalny (left-center) and Koshelev (far right) volcanoes rise above the Kurile Lake caldera to the SW, one of the scenic highlights of the Kamchatka Peninsula. Kambalny is the southernmost large volcano in Kamchatka. Both volcanoes have produced 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.

Thumbnail Photo (see caption)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.

Thumbnail Photo (see caption)Koshelev (upper right) is one of the southernmost active volcanoes on the Kamchatka Peninsula, seen here SW of the Kurile Lake caldera. It contains four main cones constructed along an E-W line over a Pleistocene edifice with the central and highest peak being the youngest. An explosive eruption occurred at the end of the 17th century. Alaid, the northernmost volcano of the Kuril Islands, is the peak on the left horizon.
