The summit of Cinder Cone contains nested craters with several crater rims created as a result of changes in vent location and eruption intensity. The scoria cone was formed during eruptions several hundred years ago in NE Lassen Volcanic National Park. Prospect Peak, an andesitic shield volcano capped by a small pyroclastic cone, is the forested peak in the background NW of Cinder Cone.
