LONG VALLEY,<br />
CALIFORNIA<br />
Huge eruption 760,000 years<br />
ago formed Long Valley Caldera<br />
and ejected flows of hot glowing<br />
ash(pyroclastic flows), which<br />
cooled to form the Bishop Tuff.<br />
Wind-blown ash from eruption<br />
covered much of the Western<br />
U.S.<br />
Remains active and may erupt<br />
again, so is monitored<br />
