Cinder cone. 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.
A tuff cone, sometimes called an ash cone, is a small monogenetic volcanic cone produced by phreatic (hydrovolcanic) explosions directly associated with magma brought to the surface through a conduit from a deep-seated magma reservoir. They are characterized by high rims that have a maximum relief of 100–800 meters (330–2,620 ft) above the ...
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). [ 3 ]
Lava Butte is a cinder cone in central Oregon, United States, just west of U.S. Route 97 between the towns of Bend, and Sunriver in Deschutes County.It is part of a system of small cinder cones on the northwest flank of Newberry Volcano, a massive shield volcano which rises to the southeast.

Gabrielse Cone is a remarkably fresh, clearly postglacial monogenetic cinder cone, located in the Tuya Volcanic Field in British Columbia, Canada. It is about 400 m (1,312 ft) in diameter and has a central crater about 30 m (98 ft) deep. It is Holocene in age and to its northeast appears to be breached with the remnants of a lava flow.
Scoria is a pyroclastic, highly vesicular, dark-colored volcanic rock formed by ejection from a volcano as a molten blob and cooled in the air to form discrete grains called clasts. [1][2] It is typically dark in color (brown, black or purplish-red), and basaltic or andesitic in composition. Scoria has relatively low density, as it is riddled ...
Eve Cone is a well-preserved black cinder cone on the Big Raven Plateau, British Columbia, Canada. [1] It is one of the 30 cinder cones on the flanks of the massive shield volcano of Mount Edziza that formed in the year 700, making it one of the most recent eruptions on the Big Raven Plateau and in Canada.
