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 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). [3]
It last erupted approximately 8,500–10,000 years ago and filled the valley with volcanic debris, raising the valley level to 400 feet above Clear Lake. [1] The Clear Lake Volcanic Field is the site of Late Pliocene to early Holocene activity and consists of lava domes, cinder cones, and maars [2] with eruptive products varying from basalt to ...
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 volcanoes with historical eruptions include: Mount Rainier, Glacier Peak, Mount Baker, Mount Hood, Lassen Peak, and Mount Shasta. Renewed volcanic activity in the Cascade Arc, such as the 1980 eruption of Mount St. Helens, has offered a great deal of evidence about the structure of the Cascade Arc. One effect of the 1980 eruption was a ...
