Black Butte Volcano
-- Geographic Setting, Geologic and Eruptive History
Two of the main eruptive centers at Mount Shasta,
the Shastina and Hotlum cones were constructed during
Holocene time, which includes about the last 10,000
years. Holocene eruptions also occurred at Black Butte, a group of
overlapping dacite domes about 13 kilometers west of Mount Shasta. ...
The extrusion of the
domes about 9,500 years ago was accompanied by the formation of
pyroclastic flows
which extended more than 10 kilometers south and
5 kilometers north of the domes.
