A volcano crater filled with water---CALDERA
Yes, although technically, strato-volcanoes *are* cinder cones (composite cones), built up of layers of ash. But the term "cinder cones" (ash cones) is usually applied to smaller cones that form within the vicinity of large volcanic calderas, such as Crater Lake in Oregon. They may be associated with either strato-volcanoes or shield volcanoes.
