The Cinder Cone in Lassen Volcanic National Park is a
700-foot-high volcanic cone. Now dormant, the cone was formed in two
eruptions of ash and volcanic cinders in the 1650s, as indicated by recent
geologic studies of the volcano. The cone was built to a height of 800 feet
above the surrounding area and spread ash over 30 square miles around it.
The black and charred-looking Cinder Cone is bare of any sort of life and
together with the surrounding lava flows and ash deposits make for an
interesting sight, a lesson about how volcanic activity can change an area.
