The Vanishing Ship Mystery 00:06:00
It's like when you go to see a magician show and he makes something huge like an elephant disappear before your very eyes.
You know it's a trick, but you still can't imagine how it could have been done.
Such was the case in 1872 when an entire ship vanished in the Mississippi River, a very public place, with no wrecks, no sinkings reported at all.
What could have happened to the SS Iron Mountain?
That's coming right up on Skeptoid.

The disappearance of the SS Iron Mountain.
We're all familiar with ship disappearances in the Bermuda Triangle.
Though many say that they're the result of some supernatural force, it's far more likely that each incident is a case of a big, stormy ocean taking its toll on small, poorly maintained, or simply unlucky craft.
But when a ship disappears without a trace from a river, it's harder to imagine an explanation.
And the legend of the SS Iron Mountain is difficult to explain away.
Here's how her story is usually told.
This is an excerpt of the version on paranormal.about.com.
In June 1872, the SS Iron Mountain steamed out of Vicksburg, Mississippi with an on-deck cargo of baled cotton and barrels of molasses.
Heading up the Mississippi River towards its ultimate destination of Pittsburgh, the ship was also towing a line of barges.
Later that day, another steamship, the Iroquois Chief, found the barges flowing freely downriver.
The tow line had been cut.
The crew of the Iroquois Chief secured the barges and waited for the Iron Mountain to arrive and recover them.
But it never did.
The Iron Mountain, nor any member of its crew, were ever seen again.
Not one trace of a wreck or any piece of its cargo ever surfaced or floated to shore.
It simply vanished.
Some versions go on to say that ghostly voices can be heard near the site screaming, they're trying to hurt me!
Help!
As with most legends, there is some truth and some fiction.
Let's see if we can separate the two.
The Mississippi River was and is the most important navigable river in the country.
In parts, it's over a mile wide and plenty deep enough to swallow a steamship.
Near the region in question, the present-day river is about three-quarters of a mile across, but 150 years ago, she may have been much wider, especially during flood season.
It is conceivable that a ship could have sunk rapidly with no one on shore noticing, especially in a time before radio.
It would be unusual for no wreckage or debris to be found.
Nearly every part of the ship and its cargo was buoyant.
The river was a highway, and one of the dozens of other ships also on the river should have seen wreckage or cargo floating downstream.
The shores in that region were dotted with farms, plantations, and towns, with frequent riverboat landings to provide the population with supplies and mail, and also to transport cotton and other goods north.
Riverboats had regular routes, but stops would be scheduled according to where cargo needed to be.
These comings and goings were reported in local newspapers.
Because of this, we know that there definitely was a sternwheeler on the Mississippi River called the towboat Iron Mountain.
She was launched in 1872 and served for 10 years.
At 181 feet long, she was a giant and modern with all-steel boilers, the first on the river.
This was a ship that everyone on the river would recognize.
It is correct that she was a cargo vessel that also towed barges, and she did have the route from Vicksburg to Pittsburgh, her home port.
Two points for the legend, but those are quickly subtracted.
The date in the legend must be wrong.
1872 is the year she was launched, not the year she vanished.
Newspapers report her comings and goings all through the 1870s.
The picture that normally accompanies the story on the internet is obviously wrong, even at a glance.
It depicts a small side wheeler, not a multi-decked sternwheeler.
The main picture for this edition of Skeptoid depicts the actual Iron Mountain, as we can tell from the letters IM suspended between her stacks, and the most obvious clue, it says Iron Mountain on the aft portion of her superstructure.
Here's the interesting part.
She did disappear.
But it was in 1882, 10 years after the legend states.
What follows is the story that fits the research.
On March 26, 1882, the towboat Iron Mountain was steaming north from Vicksburg, towing five empty barges.
After she left Vicksburg, the next reported sighting wasn't of the vessel, it was of her five empty barges, which had been cut loose and were coming down the river, presenting a hazard to navigation.
Such occurrences were not uncommon.
The Mississippi is notoriously difficult to navigate, as the water level changes and submerged objects shift and can't be seen.
A ship pulling barges would cut them loose if there was trouble.
Barges Cut Loose in Flood 00:02:23
This could include running aground or even having an issue with the boilers.
Also, the river was in a flood state so severe it became known as the flood of 1882.
It was the largest flood on the Mississippi in recorded history up until that time.
This meant that riverboat captains were steaming blind, as any obstructions they'd memorized were now underwater, in a different place, or replaced by other unseen hazards.
The Iroquois chief was also a real vessel, and she did see the barges and collect them.
As was the common practice, the barges were towed to port, and there they awaited the Iron Mountain's return to pick them up.
As the legend states, the Iron Mountain never returned.
In a world that can feel overwhelming, spreading thoughtful, evidence-based content is one of the best ways to make a positive impact.

Doubting the Field Discovery 00:04:43
The reason for the failed pickup is pretty well documented.
Newspapers reported the incident across the region.
There was no mystery.
According to the Weekly Louisianian of April 1st, 1882, About 10.30 last night, the towboat Iron Mountain, just 25 miles above Vicksburg, struck an obstruction and sunk in three minutes.
All saved except the stewardess, Mrs. Ellen Otterman, colored.
It's as simple as that.
Most likely she hit a submerged tree that ripped a hole in her side.
A great many riverboats succumbed to the same fate.
But the story doesn't end there.
The next day, as men went to survey the damage, they were surprised that the Iron Mountain had indeed vanished.
An extensive search was conducted, and while some parts of the ship were located downstream, the ship itself could not be found.
It was surmised that the river had risen and floated the stricken vessel off the snag and then downstream, where she finally sank beneath the muddy waves.
It wasn't until several months later that her wreck was found.
Oddly, it wasn't found on the river, but in a field on a former plantation called Omega.
How did a large sternwheeler get off the river and into a field?
As was mentioned before, the Mississippi River was flooding.
Near where the Iron Mountain ran into trouble, the river had broken through a levee at Omega Landing.
As the river poured through the levee, so must have the Iron Mountain, now miles downstream from where it was originally damaged.
A report from the Public Ledger of Memphis, dated June 24th, 1882, tells this story.
An incident to be remembered concerning the flood of 1882 will be the sinking of the towboat Iron Mountain, which occurred on the night of 26th of March.
The weather was dark, drizzly, and foggy, the pilot not being able to tell where they were at the time.
It was supposed that she struck a stump and sunk in 100 feet of water, and her owners never expected to see or hear anything of her again.
Now, here comes a story, with the officers of the steamer Goldust as authority, that the Iron Mountain has been found in a field two miles and a half back of Omega, or Stumpy Point, the place where she was supposed to have gone down.
The wreck is said to be high and dry and comprises the hull, machinery, and a small portion of the woodwork.
Thus, we have a complete story of the life of the Iron Mountain on the Mississippi.
With the Iron Mountain lost, the crew went on to work on other ships.
We even have a record of the barges.
They were carried by the Smoky City back upriver in May of that year.
I was unable to determine what was done with the wreck, but it was probably scrapped.
A record from the Merchants Exchange of St. Louis shows the following.
March 25th, 1882, towboat Iron Mountain, sunk near Omega Landing, was a total loss.
Valued at $65,000, insured for $20,000.
Well, it sure wasn't an insurance scam.
To put things in perspective, the Iron Mountain was one of over a dozen wrecks for March 1882 alone.
Ships were sinking all the time in the Mississippi, not for any paranormal reason, but simply because it was a difficult waterway and there were a lot of ships.
With newspapers reporting not only the sinking, but also the finding of the vessel, how did the legends start?
Based on the many stories I've read, it seems that they're all copying each other.
The earliest version of the legend I could find was in the Frank Edwards book, Stranger Than Science.
Published in 1959, this was Edwards' second book of embellished stories, continuing a tradition established by Charles Fort decades earlier.
The book was popular, and it's possible that he was the originator of the tall tale that has been repeated ever since.
Books published as recently as 2010 still report the vessel as vanished without a trace.
It's a shame that folklorists and paranormal enthusiasts need to embellish what is an interesting story in its own right.
The case of the Iron Mountain is a fun puzzle to solve, but it's definitely solved.
Or is it?
Just when I thought all the questions had been answered about the Iron Mountain, I found an article in the public ledger calling into doubt the finding of the vessel.
This is the same paper that on June 24th said the hull had been found.
On July 1st, they reported this.
That seems to be a canard about the finding of the hull and machinery of the towboat Iron Mountain out in a field two miles back of Omega, Louisiana.
Some pieces of the cabin were found, but the search for the hull has been abandoned as fruitless.
So is the legend true?
Solving the Iron Mountain Puzzle 00:02:01
Hardly.
While I was unable to find confirmation of the wreck being found in the field, the legend remains just a fairy tale.
We know without a doubt what happened to the Iron Mountain.
The only question is whether the hull lies beneath the mud of the river or was found in a flooded field.
I maintain that the actual story is far more interesting than the legend.
