A group of small cinder cones outside southeast rim of Fisher caldera. The largest cone, on the left, is about 300 m high. These cones formed during a single eruption and produced a lava flow (red area in foreground) that traveled ~9km southward, nearly reaching the Pacific Ocean. In the background is the eastern caldera lake (far right), the eastern caldera wall, and the low area outside the eastern caldera (center). View is to the north.
