A cinder cone (or scoria cone [1]) is a steep conical hill of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or scoria that has been built around a volcanic vent. [ 2 ] [ 3 ] The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent.
Roden Crater is a cinder cone type of volcanic cone from an extinct volcano, with a remaining interior volcanic crater. It is located approximately 50 miles northeast of the city of Flagstaff in northern Arizona, United States. [4]

Cinder Cone is in Lassen Volcanic National Park. Cinder Cone is a 700 ft (210 m)-high volcanic cone of loose scoria. [5] The youngest mafic volcano in the Lassen volcanic center, [6] it is surrounded by unvegetated block lava and has concentric craters at its summit, [5] which have diameters of 1,050 ft (320 m) and 590 ft (180 m).

Cinder cones typically only erupt once like Parícutin. As a result, they are considered to be monogenetic volcanoes and most of them form monogenetic volcanic fields. Cinder cones are typically active for very brief periods of time before becoming inactive. Their eruptions range in duration from a few days to a few years. Of observed cinder ...
Interior of Amboy Crater showing a lava lake and the distant breach in the cinder cone rim. Interior of Amboy Crater from near breach showing lava lakes. Amboy Crater is a dormant cinder cone volcano that rises above a 70-square-kilometer (27 sq mi) lava field in the eastern Mojave Desert of southern California, within Mojave Trails National Monument.
Schonchin Butte is a cinder cone on the northern flank of Medicine Lake Volcano in the Cascade Range in northern California. Frothy lava, cooled in the air, created the large cinder cones throughout Lava Beds National Monument. It is named for Old Schonchin, a chief of the Modoc people during the late nineteenth century. Erupting more than ...
The tephra accumulates in the vicinity of the vent, forming a cinder cone. Cinder is the most common product; the amount of volcanic ash is typically rather minor. The lava flows are more viscous, and therefore shorter and thicker, than the corresponding Hawaiian eruptions; it may or may not be accompanied by production of pyroclastic rock.
