Notes
Slide
shows
a
crater
in
front
of
Mount
St.
Helens.
These
craters
were
caused
by the
ash
flow
that was
blasted
out
of the
main
crater
during
the
initial
eruption
on
May
18.
The
ash
contained
volatile
gases.
As the
gases
leaked
out
of the
ash
, the
crater
would
form
as the
ash
collapsed.
The
crater
is
approximately
200
meters
across
at the
top
and
probably
100
meters
deep.
This
view
looks
more
like
a
lunar
landscape
out
in
front
of
Mount
St.
Helens.
There were
craters
of this
type
all
over
the
area
,
littering
it.
Subjects (LCSH)
Volcanic gases
Volcanic ash, tuff, etc.
