Chaos Crags, Lassen Volcanic Park, California. The Crags are a
cluster of rhyodacite domes near Lassen Peak. Rubble in the foreground extending
to the base of the Crags is a large rockfall-avalanche deposit that was generated
approximately 300 years ago by three separate explosive events that caused
the domeface to collapse. This
deposit is called the Chaos Jumbles. Photograph by R. Forrest Hopson.
