6,000 years ago, this area was still just sea water.

gas, jet fuel, milk cartons,

diapers, and lubricant.

these white clouds are just water vapor.

but below are black lagoons filled with toxic wastewater,

a by-product of refining crude.

aerators pump oxygen into the ponds

to feed natural microbes that help neutralize the sludge.

but millions of pounds of chemicals from this refinery

still make it into the surrounding environment

each year.

what makes this refinery unique

is that it's just a stone's throw

but it's actually bauxite,

with less than a hundred casualties

and full control of the city.

this marble obelisk was completed in 1908

to mark the site of the last conflict

fought on the u.s. mainland against a foreign nation.

jackson has been a hero in this town ever since.

much has changed along the banks of the mississippi river

since the days of steamboats and slavery.

vast fields of cotton and sugarcane

have been replaced with new industries

and futuristic-looking landscapes, like this one.

as a "tailings pond." this red lake is what's known

at first it looks like southern red clay,

to guide them upriver.

a toxic byproduct of making rolled aluminum foil.

this pond contains 120 million cubic yards of it--

more than the earth that was removed

to build the suez canal.

the best way to grasp the size of these enormous facilities

is to see them from the air.

this one is a holding tank for phospho-gypsum,

the byproduct of a nearby fertilizer plant.

these facilities lie in a vast industrial corridor

known as "cancer alley."

it stretches 85 miles,

from new orleans to baton rouge,

and is home to more than 130 industrial plants.

becnel was soon able to buy back the estate

along river road today.

in the early 1800s,

almost half the sugar consumed in the u.s.

was louisiana sugar.

this vast estate, known as evergreen,

was built on sugar cane profits.

with 37 carefully preserved buildings,

the most intact plantations it's considered one of

in the south.

in the early 19th century,

pierre becnel, the estate's owner,

spent so much money remodeling his family home

that he went bankrupt and had to sell the place.

but with sugar so profitable,

but sugar cane continues to be grown in great quantities

and the plantation's slaves.

they lived here, in these simple cabins.

great profits from sugar would not have been possible

without slave labor.

it was backbreaking work,

and in 1811,

slaves in this parish rose up--

the largest slave revolt ever to take place in the u.s.

some 500 slaves marched downriver towards new orleans,

but were quickly attacked by a militia of planters.

many of the slaves fled into nearby swamps.

most were shot,

and others were hanged.

in the early 19th century,

and settled in what's now texas instead.

but on mardi gras day, 1699,

a second group of french settlers

finally located the mouth of the great river.

these days, gps guides 6,000 ocean vessels a year

from around the world

right into the mouth of the mississippi.

a single bulk carrier like this one

can be loaded with more than 100,000 cubic meters of grain,

which will be exported to countries like egypt and china.

this port at new orleans

is part of the biggest grain and soybean export hub

in the u.s. today.

in louisiana,

cotton and sugar were louisiana's top crops.

they were grown here,

on plantations that line louisiana's famous river road,

which follows the mississippi from new orleans to baton rouge.

when it was constructed in 1839,

the oak alley mansion was set at the end

of a double row of 28 oak trees

leading from the river to the house.

today, this avenue of great trees is popular with tourists...

and hollywood.

"interview with a vampire" and "primary colors"

were both filmed here.

it's not planting season yet,

containing the graves of nearly 4,000 union soldiers.

each uniform runs into the hundreds.

over just one weekend, they play out, step-by-step

a battle that lasted more than six weeks.

once the union troops cut off supplies,

ran out of food port hudson's defenders

and were forced to eat their own horses,

and even rats, to survive.

on july 9, 1863,

after hearing of the fall of vicksburg,

those who were left finally laid down their arms and surrendered.

but by then, both sides had suffered huge casualties,

with thousands dead or wounded.

just south of the battlefield

lies the port hudson national cemetery,

each authentic cannon can cost tens of thousands of dollars.

buried here in tidy rows. the confederate dead weren't

their bodies were left in the trenches where they fell.

the victory at port hudson finally gave the union forces

control of the entire mississippi.

but the civil war that battles had been waged wasn't the first time

to control traffic and trade on this river.

arriving in new orleans, the harvest legend,

a 45,000-ton bulk carrier,

prepares to make a 135-degree turn against the current.

before these giant ships

even enter the mouth of the mississippi,

they're required to have

a licensed local river pilot on board

from across the south.

the civil war battles that brought an end to slavery

are still being re-lived today.

smoke from canon fire rises over port hudson.

in may 1863,

while major general ulysses s. grant

was attacking vicksburg,

more union forces gathered here,

hoping to seize control

of one of the last confederate strongholds

on the mississippi river.

the little-known battle of port hudson

was an important turning point in the civil war.

every year, 500 men and women gather here

like louisiana... narrator: there's no other place

they are passionate re-enactors

who live in period tents before the battle begins.

most are louisiana natives;

some even descendants of the confederate soldiers

who survived the siege.

on may 23rd,

more than 30,000 union troops arrived to take the fort.

those in red uniforms

were from an elite fighting unit called the zouaves,

the green berets of the day.

despite being outnumbered, the confederates fought hard.

for a captivated crowd, these re-enactors try their best

to capture each important turn of the siege.
