Hammonasset
(Captions
Transcript)
Intro
Ralph:
Here
we
are
at
the
Meig’s
Point
area
of
Hammonasset
State
Park.
What
we
have
here
is
a
long
pile
of
boulders
along
the
shore,
which
extends
offshore
towards
Faulkner’s
island
in
the
background.
Many
of
these
boulders
are
quite
different
from
each
other,
and
they
form
a
huge
pile.
What
do
you
think
happened
in
the
past
to
cause
what
we
see
here
now?
Hammonasset:
Rocks:
Bedrock
Ralph:
Here
we
are
in
front
of
the
bedrock
just
north
of
the
boulder
field
at
Hammonasset.
You’ll
see
that
it’s
a
salt
and
pepper
black
and
white
color
because
it’s
predominated
by
quartz
and
mica.
It’s
also
lightly
banded
or
foliated.
Check
out
the
zoom
tool
and
the
rock
chart
to
see
if
you
can
ID
this
bedrock.
Bedrock
Acid
Test
Ralph:
Okay,
let’s
do
the
acid
test
on
this
bedrock
outcrop.
Well,
it
didn’t
fizz,
so
it
can’t
be
marble
or
limestone.
Hammonasset:
Rocks:
Boulder
Field
Ralph:
Here
we
are
in
the
middle
of
the
boulder
field.
It’s
a
long
narrow
band
that
extends
along
the
shore,
and
it
even
can
be
seen
out
off
shore
as
those
boulders
sticking
out
behind
me.
From
this
vantage
point
the
boulders
all
look
fairly
similar,
but
as
we
take
a
close
look
you’ll
see
there
are
some
very
striking
differences
in
them.

Ralph:
This
is
one
of
the
largest
boulders
here.
As
you
can
see,
it’s
rounded,
it’s
about
four
meters
in
diameter,
and
these
color
bands
are
derived
from
the
minerals
that
make
them
up.
We
have
pink
feldspar,
some
mica,
and
some
quartz.
Check
out
the
zoom
tool
and
rock
chart
to
identify
this
rock.

Ralph:
Here’s
a
medium
sized
boulder.
It’s
rounded,
about
a
meter
in
diameter,
and
it
has
sort
of
a
black
and
white
salt
and
pepper
look
because
of
the
minerals
that
make
it
up,
predominately
quartz
and
mica.
Check

the

tool
and

chart
to
identify
this

Ralph:
Here’s
a
medium
sized
boulder.
It’s
rounded,
about
one
meter
in
diameter,
and
it
has
this
rusty
brown
color
because
it
has
high
iron
content,
so
it’s
stained.
Check
out
the
zoom
tool
and
rock
chart
to
identify
this
rock.

Ralph:
This
small
boulder
is
a
little
bit
different.
It’s
very
round,
as
you
can
see,
and
it’s
quite
smooth.
The
small
crystals
that
make
it
up
give
it
a
very
uniform
gray
color.
There’s
no
banding
or
foliation.
So
check
out
the
zoom
tool
and
rock
chart
to
see
if
you
can
identify
this
rock.
