Cutbank Kills: Point Bar or Cut Bank? Depositional Processes The consequences of misunderstanding sedimentological processes can be fatal. Learn how.

2. This
is
very
sad.
A
mineral
owner
drowned
in
the
river.
But
-­‐-­‐
was
it
an
accident
or
a
murder?
Here's
a
temporary
marker
near
where
they
pulled
him
out.
How
horrible.

3. He
had
just
leased
his
land
containing
thick,
briAle,
highly
fracable
Woodford
shale
for
$2
million.
He
also
liked
noodling
for
caFish
in
the
river
whenever
they
opened
up
the
floodgates.

4. Oh
no.
The
river
was
in
flood!
If
he
did
not
understand
how
rivers
flow
-­‐
how
they
deposit
sand,
and
also
erode,
then
he
could
have
been
in
trouble.
I
think
he
was
murdered
for
his
money!

5. Check
it
out.
He
thought
it
was
a
point
bar,
but
it
was
a
cutbank.
Point
bars
are
good
for
wading.
Ah
yes!
A
point
bar
is
where
sand
is
deposited.
It
makes
nice
river
banks
and
mini-­‐
beaches.

This
is
what
it
is
…

7. Three
young
guys
drowned
noodling
for
caFish.
The
stepped
off
a
cutbank
and
then
the
current
swept
them
into
some
bushes.
They
were
trapped
under
water.
The
deep
water
is
where
the
caFish
like
to
forage
for
food.

8. I
think
he
might
have
thought
he
was
on
the
point
bar,
but
the
river
was
in
flood,
and
it
changed
course.
That
is
what
happens.
So
a
point
bar
became
a
cut
bank?
That
is
scary.
Yes!
and
it
is
very
scary...
respect
fluvial
systems,
but
especially
when
they
are
in
flood.

9. Yes!
This
is
a
great
moment
to
look
at
sedimentary
systems.
Ancient
point
bars
make
great
traps
for
oil.
Also,
it
is
why
sand
deposits
are
so
tricky
to
map.
Great!
Let's
review
and
see
what
we
learn!
