The summit caldera rim of Yunaska is seen from an older volcanic center on the western side of the island. The younger eastern complex contains two nested calderas. A young lava flow to the far right descended through a notch in the caldera rim. The peaks in the background are (left-to-right) of Carlisle, Cleveland, and Herbert volcanoes.
