Cinder Cone - John Seach

A cinder cone is formed by explosive eruption or lava fountain. It is composed of mostly loose material.
The cone may be beautifully symmetrical with slopes of 30-40 deg, and height of several several
hundred metres. The diameter can be several km. A cinder cone is composed of material ranging
in size from 4 to 32 mm (lapilli or little stones).
