7/15/15 Report - The Big Three Factors Of Hunting In Dry Sand. How Waves Move Very Big and Small Objects. The Langeid Viking Sword Finally On Display.


Written by the TreasureGuide for the exclusive use of treasurebeachesreport.blogspot.com.


Ornate Viking Sword.

A deadly weapon and symbol of power -- jewellery for a man, with magical properties. The sword gave power to the warrior, but the warrior's strength could also be transferred to the sword. That is how they were bound together: man and weapon, warrior and sword.

This sword was found in Langeid in Bygland in Setesdal in 2011. It is a truly unique sword from the late Viking Age, embellished with gold, inscriptions and other ornamentation. The discovery of the sword has not been published until now, when it is being displayed for the first time in the exhibition 'Take It Personally' at the Historical Museum in Oslo...

Here is the link for the rest of that article.

When talking about where to hunt for gold jewelry on a dry beach, I could sum up ninety percent of what needs to be said in a couple of paragraphs.  It isn't that complex.  It doesn't change as much as the wet sand or water does.

It comes down to looking where the most people of the right type do the right things.  The primary factors are (1) number of people, (2) type of people and (3) their behavior.  Number is obvious.  Go where many wealthy people who wear a lot of gold either participate in very active behaviors or are involved in taking off or adjusting jewelry.  Example: busy volleyball court at a resort that attracts a lot of active wealthy people.

Of course there is a lot more that could be said, but that tells you the vast majority of what needs to be said.  You can't sum up where to hunt wet sand and shallow water so easily. There are a lot more factors and things change a lot.

Number of people, type of people and type of activities would be a start for those areas too, but it would only be a start.  After those factors you would want to include how the water moves sand and objects, and that is quite complex.

I've been at this a long time. I'd say something over thirty years, sometimes not as actively as others due to different careers and things, but one of the most surprising things to me is how much I continue to learn.

I knew a lot about where to look before, but a lot of the time I didn't know why.  I didn't know how it all worked.  In the last few years, I've filled in some of the blanks. I now understand some things that puzzled or confused me.  Having a more complete understanding helps in a variety of ways.

A few days ago I talked about coins being flipped up and over the face of a cut.  I first told what I saw happen on one occasion maybe twenty years ago.  I then received and posted reports by others verifying what I'm now calling flip-ups.  In a case reported by Clint L., the object flipped was a gold ring.  In a case reported by Bill P., the object flipped was a reale.

You might have been skeptical.  You might have wondered how objects could flip up and over a two foot cut.

I think the illustration that I provided in my 7/13 post might have satisfied many of you.  However if you still are not sure, you might be satisfied after reading today's post.

I came across a book entitled, Wave Action In Relation To Engineering Structures, by D. D. Gaillard, Captain, Corps of Engineers, U. S. A., 1904.  It is a free Google ebook.  It is a very technical and mathematical engineering book, and isn't easy to quickly browse.  You'll find the link below.

The book provides a lot of good information - much that has been widely published and easily available in recent years, but also details of a lot of experiments and additional specifics that you might not have read before.

Below are just a few examples many similar examples found in the book.  Whether you find these anecdotes convincing or not, I'm sure you'll find them interesting.

Just to give you the idea here are a few.


And a Florida example.


Like I said, that is to give you the idea.  You can find more examples like this as well as experimental data and mathematical calculations in the book.

Click here to go to that book.

After these remarkable examples, you might not find it hard to believe that something like a coin or ring could be flung up and over a cliff.

The power of the sea is amazing.  These events are almost beyond belief, yet this is a very credible source, and others have attested to similar things.

The book provides evidence of other things that I've talked about in the past.  The effect of density on how items are moved is one important one.  You can find the required force calculated for different examples. The density and surface area of the objects are factors, just as is the case for coins and jewelry. Precise mathematical formulae are provided.

While many of the principles I have presented are supported in this book, you will have to downscale many of them to apply to smaller objects.

You might wonder why you would want to know this.  If you do know this type of material, you can look at the waves and know a good bit about the bottom.  You can easily estimate the depth of the water where the waves are breaking, for example.  You will know where sand is building and where it is getting washed away.  That might tell you where to hunt when the water calms down.

If you know that the depth of the water is about one half the wave length ( distance between peak to peak) where the waves are breaking, you can look out and immediately have some idea about how deep or shallow the water is there.  If you keep a mental note of that, you will know when the near shore sand is coming or going and something about the shape of the bottom in the shallow water at that location.

On the deep side of the breaking waves, the bottom is not being affected much.

Most importantly, you'll be able to get an idea of where and when objects will be moving.  As a result you'll better know where to look to find things.

There is a great deal to it.  I have learned a lot from experience, and I have learned a lot in recent years, putting together my own observations and experiences with what I read.  I am enjoying the learning process and it is continuing at a rate that surprises me.

I got a lot more from that book that applies to metal detecting in very practical ways, but I can't put all of that into one post.

The next two days the Treasure Coast surf is supposed to be very calm.

7/13/15 Report - Explanation Of Flip-Ups. Dating A Coca Cola Bottle. Palm Beach Island Detecting.


Written by the TreasureGuide for the exclusive use of treasurebeachesreport.blogspot.com.



Straight Side Fort Pierce Coca Cola Bottle.


Yesterday I gave you a link to a web site that lists the start dates of various Coca Cola Bottling Companies.

Here is an old straight-side Fort Pierce Coca Cola bottle that I found over a year ago.  I just cleaned it up a bit.

Unfortunately the top is badly damaged.

A few years ago I found and sold a West Palm Beach straight-side Coca Cola bottle that was more damaged than this one, and it sold for over $100.

The reason I am showing this one today is to show you the relevance of the link I gave you yesterday.

That site says the Fort Pierce bottling company began in 1914.

KovelsKomments says, Straight-sided glass bottles were used by Coke bottlers from about 1903 to 1916-17, when the now-standard Coca-Cola bottle was introduced.

That narrows the date of this bottle down pretty well.

It would be 1914 - 1917.

That is pretty good for a bottle that doesn't have much else that would give you the date.

I was thinking about what Clint L called flip-ups.  Those are coins or other objects that get flipped up and over a cut and settle just behind the cut.

There are times, when I think it appears that objects have flipped up but when there might be another explanation.  There are times when a layer of shells is deposited, and a few other things might be in with the shells.  The beach then cuts through that deposited layer leaving some of the layer behind the cut.  That happens with some frequency.

I know one detectorist who has found most of his cobs by hunting a thin layer of shells laying right behind a cut.  He thoroughly hunted one such area daily and found a good number of heavily worn half reales.  I found a few in the same location.  These were small half reales about the same size as some of the shell pieces.

Actual flip-ups do happen though.  Clint described one case, as did Bill P., and I've seen it myself.  In the case I recall best, a coin was resting on a slanted slab of sand that had just been separated from the face of a small cut.  It appeared to me that the coin had been in the sand that was being eroded.  That could have left the coin in a very peculiar vulnerable position on a slanting and very irregular surface.  It was definitely not settled into the sand.  I can't recall it in any more detail than that.

The illustration above shows what I think probably happens.  An object is laying on or in loose sand in front of the cut.  A wave crashes at the foot of the cut and splashes forcefully up, throwing any vulnerable objects.

When beaches are cutting a lot, water will be crashing right on the cut.  Waves can hit a cut very forcefully, splashing up.  I'm sure you've seen it.  The loose sand near the foot of the cut will direct the water and force up and back.

I've decided to make a distinction between flip-ups, like those I'm talking about today in which an object must jump up at least a short distance, and coins or objects that flip over but do not really jump - not much more than the length of the object itself.

Flipping coins are very common, but most of the time they do not flip very far at once  I remember watching a coin flip the last time I was on the beach.  In that case, I had just dropped the coin.  Before it had settled into the sand a rush of water came by and it flipped over.  Immediately after that rush of water went by, it settled.  The next couple of very small waves put a thin layer of sand over the coin, after which it did not move.

Anyhow, I wanted to distinguish between flip-ups, which flip good distances (I might start calling them jumps or something like that) from flips, which are much more common and less surprising.

I think flip-ups, or jumps, might happen

Tony (penzfan) got this nice photo while hunting on the Palm Beach island the other day.

He found, One .925 ring, One Copper Bracelet, One Snake Ring, One Russian Ruble and some clad.

Below is a photo of his finds.

No significant change in beach conditions on the Treasure Coast again.  Expect very smooth surf towards the end of this week.

We've been having some nice low tides.

Happy hunting,

7/12/15 Report - Steamboats On The Indian River. Flip-ups And Eye-Balling. Good Coca Cola Bottling Plant Web Site.


Written by the TreasureGuide for the exclusive use of treasurebeachesreport.blogspot.com.


The St. Augustine - Indian River

Terry T. has a blog on railroads and has a nice post on the Jupiter and Lake Worth Railroad that you might want to look at. 

 http://jterryt.blogspot.com/

I once talked about steamships traveling the Indian River.  There were a few docks where steamboats such as the St. Lucie made regular stops.  One was down by Jensen.  

Here are some nice photos that Terry sent along with the links to the source of each photo

Thanks for the photos Terry.  I'll bet there is some good treasure waiting to be discovered in the Indian River.

Some of my favorite bottle finds came from the River.

Clint L. sent me the following email.


Hi. I wanted to comment on "flip-ups". I was searching south of Lake Worth Beach around winter of 1990. There was a 3 foot "berm" and it was almost to High Tide with rough winter-time waves.
I was searching around the berm and moving south when I spied a ladies Gold Nugget Ring laying at the base of the berm. As I reached to pick it up, I was hit by one of those waves and knocked off balance.

I got up and looked for the ring but it was gone. I searched about 30 minutes all the way into the water but to no avail.  I went back to the point where I was hit by the wave and was ready to continue to search the berm when I spied that very same ring laying on the edge of the top of the berm.
That wave literally, threw the ring straight up and it landed on the lip of the berm.

I always am looking around as I search because I do not need to look at the coil as I know where it is going. This habit of looking around lets me find good stuff by eye.

Another example is that at Lake Worth Beach, I have seen and recovered herring bone chains as they roll up the beach and roll back down. I found out that herringbone chains straighten out due to the micro sand particles filling up space between joints in the chain.

I saw 6 inches of a heavy Gold chain moving back and forth in the interzone where water runs up the beach. People were walking all around it. I stopped and pulled it and at the end of the chain was a 14 Kt. 3/4 oz. Maltese Cross. Surfer's necklace I bet!

Always look around when you are in the water. I saw many "pieces of seaweed" just under the surface that I scooped and it was $10 and $20 bills!! ...

You might remember that I also posted how Bill P. said his first cob find was a cob that apparently flipped up on top of the beach just behind a cut.

I've seen it happen and now have heard from others who have seen it happen too.

Clint provides some good advice about keeping your eyes open while you detect.  You can cover a lot more ground visually than you can with your coil.

Thanks or the helpful email Clint!

Here is a really good web site that gives the starting dates for the bottling plants.  I see that the Fort Pierce plant began in 1914, for example.  You'll find Coca Cola bottles from all around the country on the Treasure Coast, but our local bottles are some of my favorites.
