THE MAHOGANY SHIP - Rob Simpson's Warrnambool Shipwreck Sites

The Mahogany Ship - one of Australia's greatest mysteries

This blog has several sections and pages describing evidence for three potential shipwreck sites near Warrnambool. These are where inland shipwrecks were reported in the Warrnambool sand dunes (known as hummocks) in the nineteenth century. Scroll down for the information about each site or click on the links to skip to the separate pages about site coordinates and Q & A. 

During the nineteenth century shipwrecks were reported in several quite different places in the Warrnambool hummocks. Therefore, they cannot all be "The Mahogany Ship"! Some books about The Mahogany Ship emphasise three areas where inland shipwrecks were most often reported.

Sites 1, 2 and 3

Three sites between the Australian towns of Warrnambool and Port Fairy could be worthy of archaeological investigation. 

This article links to a video about my Site 1 and explains my Sites 2 and 3 in detail. 

"The Mahogany Ship" is probably a popular collective title for several shipwrecks stranded inland in the Warrnambool hummocks that were observed in the nineteenth century. Witnesses didn't report that they were constructed of mahogany, but several mentioned the colour of mahogany. The Mahogany Ship is therefore probably not merely one shipwreck, but several shipwrecks that were stranded inland, and they were unlikely to have been built of mahogany. However I am not suggesting that the term "The Mahogany Ship" should be abandoned.

Reading academically reputable books about the Mahogany Ship makes it clear that there were probably at least three inland shipwrecks in the 11 kilometre wide hummocks area. All were covered by windblown sand and lost by the late nineteenth century.

Site 1 is in the hummocks (sand dunes) halfway between Gorman's Lane and The Cutting (a connection to the sea from an inland lake). My reasoning is explained in a documentary video on YouTube called Quest for the Mahogany Ship. Please click on the link or if that doesn't work, copy and paste it.

The coordinates at the centre of the site are: 38°20’58”S, 142°21’38”E. To find the site on Google Earth, copy and paste the coordinates without a full stop at the end in the search bar. Please note: Use Google Earth – not Google Maps.

Site 1 - Summary of the evidence in Quest for the Mahogany Ship:  

Aerial imagery using the principles of aerial archaeology provides very compelling evidence. This coalesces with the following spoken evidence from literary sources. These are nineteenth and twentieth century reports that are compatible with one another, and with the aerial imagery:

John Mason: “halfway between Port Fairy and Warrnambool”.

Alexander Rollo: “could not be seen from the water’s edge, being high up in the hummocks”.

Alexander Rollo: “between two hummocks a quarter of a mile east of Gorman’s Lane and 4 chains north from the sea”.

Alexander Rollo: “opposite Helen Rock”.

James Rock: “halfway between Gorman’s Lane and The Cutting”.

Mrs Dickie: “close to the end of Gorman’s Lane”.

Mrs Smith: “a short walk from the end of Gorman’s Lane”.

Pat Maddon: “east of the lane, up near The Cutting”.

4:05. John Mason in 1876 spoken by Daryl Francis:

John Mason speaking:

“Riding along the beach from Port Fairy to Warrnambool in the summer of 1846, my attention was attracted to the hull of a vessel embedded high and dry in the hummocks, far above the reach of any tide. The hull was full of drift sand. The timber of which she was built had the appearance of cedar or mahogany. The wreck lies about midway between Port Fairy and Warrnambool, and is probably by this time entirely covered with drift sand.”

6:08. Alexander Rollo spoken by James Simpson (stage name James Jackson):

Alexander Rollo speaking:

“In the years 1854 and 1855, when residing at South Warrnambool, I and others were in the habit of walking along the Port Fairy beach. I remember a wreck that was lying far above high water mark. Her stern pointed towards Port Fairy and only her timbers were standing about three or four feet above the sand, surrounded with vegetation. From the position and appearance of the wreck, I am perfectly sure, she came ashore before the district was inhabited by Europeans. She could not be seen from the water's edge, being high up in the hummocks.”

16.40. James Rock spoken by Andrew Simpson:

James Rock speaking:

“There was a channel cut through the hummocks by Mr Rutledge to drain a large area of swamp considerably east of Gorman’s Lane. The wreck lies about half way between Gorman’s Lane and this channel; but, if anything, nearer the channel than Gorman’s Lane.”

I have altered the wording slightly for simplicity, but not the meaning.

It was seen a year or two later but only the top timbers, then it disappeared and has never been seen since”.

19:48 Pat Madden spoken by James Simpson (stage name James Jackson):

Pat Maddon Speaking:

“East of the lane, up near the cutting. My father-in-law had a cow that calved over that way, and when he went looking, the calf could not be found. The old cow had hidden it in the tussocks. He started to drive the cow home, thinking that she would break back to the calf, but she did not. He met up with another local resident, Doherty, and asked him to look for the calf, which was soon found. The calf was tied to the wreck until it could be brought to the farm.”

I altered the wording slightly for simplicity, but not the meaning.

Anecdotal evidence.

Site 2 is in the hummocks one kilometre (.62 of a mile) east of The Cutting. There is a very short video on YouTube showing this. It has the uninspiring title of Shape! Please click on the link or if that doesn't work, copy and paste it. The link to this video is:

Site 2 is explained further down the page.

Discovery of Site 2

I discovered Site 2 on 18-01-09. I was accompanied by my son James. I was immediately struck by the obvious symmetry of the large complex of sand and grass covered shapes looming above ground level. They are unlikely to have been created by nature. This was reinforced by further investigation.

On 19-01-09 I returned with my camera and made the video entitled Shape.

Aerial archaeology using Google Earth

For this purpose, I don't use Google Maps which is for finding streets. It is much better to use the Google Earth program – free online.

The ghostly outline of the structure can be seen on Google Earth. (Unfortunately, it is absent on updated versions.):

I have superimposed yellow lines for clarification. The wavy line is a very steep track leading up to the site. Vegetation is growing over the site and making it less recognisable.

It is not the familiar shape of a ship, but it is symmetrical. The image is quite typical of traces of buried structures found by this method. See the many articles about aerial archaeology online. Aerial archaeology is not to be confused with mere aerial photography which is taking photos from the air of objects that are completely recognisable at ground level, such as buildings or archaeological sites that have already been excavated.

The centre of the object, according to Google Earth, is at 38°21'05" S, 142°22'48" E.

Once found, click on View/Historical Imagery and slide the pointer to the extreme left. This gives an image made in 2004. (Added on 6-10-25: This is no longer so as Google Earth has updated. The image above is my screenshot of the original.)

Drought and aerial imagery

I have now realised why it may be that the older aerial images of both sites show the outlines of the buried objects more clearly. Much more vegetation covers the sites now than in 2004. Certainly, comparing my 2009 movies with my 2015 movies taken at identical places makes it very clear that there is a much thicker covering of vegetation in 2015.

There is a Wikipedia article called 2000s Australian Drought at http://en.wikipedia.org/wiki/2000s_Australian_drought

It says: "By 1995 the drought had spread to many parts of Australia and by 2003 was recognised as the worst on record."

In my opinion the 2004 images on Google Earth show more sand and therefore the outlines of what might be concealed beneath; and the more recent images show the vegetation that has grown since and covered the sand.

I am not dismayed that the more recent images don’t show the outlines and that the older images do. Different conditions, lighting and methods of photography can give quite contrasting results.

Matching of the shapes with the Google Earth outline

I visited it again on 30-10-14 with an associate. The object was to ascertain whether the outline that can be seen on Google Earth does in fact match the striking geometrical shapes that can be seen on the landscape. We used three different GPS devices – all of which gave similar results. We found that the shapes are indeed in the same place as the Google Earth outline.

Investigation of geometrical alignment

The associate and I returned on 1-11-14 to investigate whether the northern and southern sections are in geometric alignment and therefore might be two parts of one object. It is difficult to judge from the side (where the video was shot) because a hummock seems to have formed over the centre of the object. However standing on the hummock makes it possible to view the two visible sections on either side. Their alignment strongly suggests that they are sections of one large object.

I also took more photos and movies – particularly of Tower Hill in the distance.

Measurement of length

The associate and I visited it again on 15-4-15. Our aim was to measure the shapes – particularly to see whether the length is 180 feet as on Google Earth. This was confirmed, although the ruggedness of the terrain made measuring difficult. I do not claim that the measuring exercise is necessarily perfectly accurate - given the wildly undulating topography.

We returned on 16-4-15 to take more movie clips and photos. I noticed something that had not seemed obvious before. There is a symmetrical prow shape (covered in sand and vegetation) where a prow appears to be lacking on the Google Earth outline. The "prow" was measured as 20 feet long.

Therefore, as best as it is possible to gauge, the shape is about 200 feet long if the hypothetical prow is included. We did not measure the width due to the sheer difficulty of working there. But measuring it on Google Earth, the width at the widest point is about 100 feet.

The vessel seems to be unexpectedly large – but then fact has a way of being stranger than fiction!

Near the south end an irregular feature can be seen within the structure. It gives the impression that a large mast has fallen across the object on an angle. It can also be seen clearly on Google Earth. However I am not prepared to claim that it is a buried mast without proper evidence.

19th Century anecdotal evidence – Mrs Manifold

Mrs Manifold's evidence about the Mahogany Ship says (among other things) that it was "strangely designed and constructed". This evidence is second hand and relayed through others. Different versions of it appear in various books about the Mahogany Ship.

19th Century anecdotal evidence – Mr Mason

Mr Mason's evidence includes the information that "her general appearance bespoke a very slight acquaintance of the builder with marine architecture". Both of these witnesses therefore claimed that the vessel they saw was not shaped like a normal ship.

Primary source:

Letter from John Mason to T. H. Osborne, secretary of the Western Steam Navigation Company at Warrnambool in 1890. Note that the same letter does not say where the shipwreck was, although there was an accompanying map, now lost. The letter gives the opinion that it would have been a small ship – but is vague on that point. 

19th Century anecdotal evidence – Captain Mills

It is compatible with the famous and often repeated evidence of Captain Mills:

"Well to the eastward of Gorman's Lane. Proceed eastward along the beach till you bring the point of land on which the old iron church stood in line with the highest point of Tower Hill Island. The wreck would be almost in a straight line with those objects, well in the hummocks." 

The innocent sounding word "almost" suddenly becomes crucial – it is in fact almost in a straight line with those objects as my photos and movie clips show! A sighting that is truly in line with those objects ends about three kilometres to the east – where it is much more difficult to see them. It seems unlikely that Captain Mills intended one to proceed along the beach that far! Please note that the Mills evidence is second hand and relayed through a contemporary acquaintance. It is to be found without variation in many books about the Mahogany Ship.

The site is therefore "almost in a straight line with those objects, well in the hummocks".

Tower Hill from the site. The old iron church was just to the right of the peak. It is sometimes called "Tower Hill Island" because it is nearly surrounded by lakes - not because it is in the sea.

19th Century anecdotal evidence – Mr Saul and his son

It is quite possibly compatible with the Saul's fence evidence.

A letter from Saul's son on 28th April 1909 states:

"I cannot give you the exact time, but I think it must be 40 years ago, he erected a fence for the Warrnambool Borough Council across the hummocks, about three-quarters of a mile east of Gorman's Lane. When he came home after completing the contract he informed me that he came across an old wreck high up in the hummocks, and I believe he said it was to the eastward of the fence but I cannot say the exact distance. It was within a half mile of the fence and nearly buried in the sand."

"About three-quarters of a mile" plus "within half a mile" is about 1.25 miles or less. According to the Google Earth ruler, the site is 1.28 miles east of Gorman's Lane. The vagueness of the evidence makes it possible that this could be the object that Mr Saul saw – perhaps from a distance and without using an accurate method of measurement. If it was "nearly buried in the sand" by about 1869, whatever is left could be deeply buried by now.

The Lieutenant Stanley Locality Plan

The site is in the same place as the black cross on the nineteenth century Lieutenant Stanley Locality Plan that appears, in different versions, in books about the Mahogany Ship. 

A line has been drawn from the highest point of Tower Hill to the cross. The line almost transects the point of land on which the old iron church stood.

Conclusion

I believe that the symmetrical shapes above ground level are likely to have built up over a human made object. Surely it would be a seagoing vessel – although it is not the usual shape of a ship. There is anecdotal evidence that people in the nineteenth century saw a shipwreck of unfamiliar design in the Warrnambool hummocks.

In my opinion the site is worthy of archaeological investigation. I cannot, of course, judge how much of the original object might survive today. In my opinion (and in the opinions of my supporters) action could be taken to prevent further deterioration.

INVESTIGATIONS

October 25, 2016 – Ground-penetrating radar

A GPR company scanned the site, assisted by some associates. The exercise was difficult to conduct due to the extreme ruggedness of the territory. With such a large site, it was not possible to scan in fine detail during one day. The equipment was dragged and pushed - with difficulty - over the shapes. This was done in lines several metres apart.

There are no results for the northern section due to technical issues.

Seventeen objects were detected under the surface on or near the southern half at a shallow depth of about one to two metres. Deeper investigation was not attempted.

It was not possible to understand the nature of the objects.

I am very grateful to those who enabled this project - thanks so much.

February 15, 2017 – investigation with a two metre archaeology probe

The associate and I returned with a GPS device and an archaeology probe to try to find the objects. I had entered the latitude and longitude of each object into the GPS device. The device can then recreate the position – but not always with perfect accuracy. We also had marking stakes.

We were unable to find anything. The exercise was not aided by the extremely rugged territory, unpredicted heat and very strong winds. The probe got stuck in the hard sand with monotonous regularity. I returned exhausted and overheated, and had to go to a local hotel for a giant ice-cream sundae!

February 16, 2017 – more investigation with the archaeology probe

Weather conditions were not a problem. We continued to try to find the objects but were unable to do so. At the end we did find something that seemed to be wood rather than metal or rock nearly a metre below the sand – but were too exhausted to dig by then. It was not at a coordinate found by the GPR. It might only be compact sand.

March 16, 2017 – more investigation with the archaeology probe and an auger

The auger consists of half a dozen extensions, each about 1½ metres long.

The associate and I went to the site intending to drill some deep auger holes. But unfortunately, that was not to eventuate. It was a very windy day, making negotiating the site more difficult than usual. The sand was blowing to the extent that in some places it looked like snow on the vegetation.

We spent a long time pushing the archaeology probe into the ground, with the idea that if we couldn’t find something at two metres, the work of putting in deep auger holes might be self-defeating. Despite doing a lot of work with the two metre probe, nothing seemed to be touched. This could be because any remains of an object would be deeper than two metres. It seems that all we have found is very compact sand. As usual, the probe kept getting stuck.

Eventually, unable to get any clues from the probe, we decided to try the auger. It took some time to decide on a likely place to start. The site is about 1,000 square metres.

Using the auger was tough going indeed as the sand is very compact and the auger kept getting stuck all the time. Progress was unexpectedly slow and we only managed to make one auger hole that was two metres deep.

November 2 and 3, 2017 – Los Angeles movie studio scout and producer

A Los Angeles movie studio that makes documentaries about world mysteries is going to do an episode about the Mahogany Ship. I travelled to Warrnambool to show a scout and a producer the site. We had a very happy time!

November 12, 2017 – Los Angeles movie studio crew

The Los Angeles movie studio spent the day at the site filming. They were at Warrnambool during the week filming material connected with the Mahogany Ship. The documentary will be shown on American TV during 2018.

Some of the film crew assembling near the site.

January 15 to 17, 2018 – investigation with auger 

Two associates and I drilled with an auger in 7 places at the site. We drilled to depths of 2 to 4 metres. Unfortunately, we were not able to strike anything solid. 

In the future

We know, from the GPR equipment readings, that the site is at least 8 metres above sea level, and even higher than that in some sections. We also know that many metres of sand have blown onto the Warrnambool hummocks since European settlement. Plastic – invented during the 20th century – has been found more than 3 metres below the sand near the site. It seems likely that any remains of a seagoing vessel would be found at a deeper level than three metres. We can conclude that investigation at a deep level is needed. 

July 4, 2018 – deep ground-penetrating radar (GPR)

This was done by Jason Brewerton of GPR Imaging Solutions. Jason was assisted by me and an associate. He was extremely competent and knowledgeable, and did a most thorough job!

The west arm. It disappears into a hummock. I find it difficult to believe that sand dunes form at random in the shape of the symmetrical inner ribs of a sailing ship. However, I don’t want to indulge in conjecture without proof. 

Standing on the same arm, taken from the south
after the site became more overgrown with vegetation.

It is difficult to believe that such symmetry can occur naturally in sand dunes. The appearance is of symmetrical objects with a large amount of sand built over them. The arm on the left is the same arm as in the previous two photos.

The hummocks

Site 3 is in the hummocks one nearly two kilometres east of The Cutting. It includes a feature that could resemble a sand covered wall. Site 3 is explained at the end of this article.

In 1985, Jim Henry, Warrnambool historian (and mentor to me), was given information that originated from Mr R. Scutcheon of the Victorian city of Ballarat. This included a map. Between 1914 and 1920 Mr Scutcheon spent holidays in Lynch’s Road, Warrnambool.

He wrote:

“On the hummocks almost directly opposite the end of the road, about 2-3 chains [40-60 metres] in from the sea, on the side of a dune stood two masts which I and others climbed on.”

 

Using Google earth Historical Imagery, there is an outline that could resemble the prow of a ship 1.8 kilometres opposite the end of Lynch’s Road, Warrnambool. The shape is 23 metres long and 12 metres wide. It is 50 metres from the beach. The shape is symmetrical and could resemble the bow of a ship, as though the stern is too deeply buried to cause an outline. At the site I have been unable to find ridges that represent the outlines. As it is a 1.95 kilometre walk from The Cutting, I have been unable to give it nearly as much attention as the other two sites.

However I have taken photos and videos, and it has been investigated with GPR.

Copy and paste 38°21'17" S, 142°23'16" E into the Google Earth search bar, then go to Search/View/Historical Imagery/adjust the slider to 2/2007/then zoom in. The shape and the wall are then very easy to see.

Wall at Site 3

Immediately next to this shape and only 10 metres from it is an almost completely straight wall that is 200 feet long. It can be seen clearly on Google Earth and also at the site. Today it is covered in vegetation. I have been unable to measure the height, but it was taller than me and very easily recognisable. Might is be a sealer's wall? I suggest this as there is a sealer’s wall on King Island (238 kilometres south of Warrnambool) that resembles it. The Warrnambool wall is of course covered in sand, and it is therefore impossible to know what it is constructed of underneath the sand.

The centre of the "wall" is at 38°21'17" S, 142°23'17" E.

Articles and photos can be found online by typing in “Sealer's Wall on King Island”.
