4/5/20 Report - Pre-Columbian Indigenous Metallurgy and Tumbaga. An Old Find. FDOH Dashboard.


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

Source: See Penn.Museum link below.

AD 1519, central Panama: the conquistadors were angry. They had promised the Spanish court a mass of gold in return for investing in their risky transatlantic voyage. But having failed to find the legendary gold mines of the region, they had resorted to looting the treasuries of the local chiefs and the grave goods of native cemeteries. Then came the shock. As the soldiers began to melt down the heaps of ornaments they had gathered up, they discovered that scarcely anything was made of pure gold. Rather, the metal was debased with large amounts of copper....

You might also like the article entitled Pueblo Indians Adaptation of Spanish Metallurgy, which discusses a 17th century site.  Here is the link.


Here is one illustration from that article.


It reminds me  of some of the small pieces that I was picking up when cobs were found earlier this year.  Some of those were modern, but not all of them.

The Aztecs certainly had lots of gold, but nowhere near as much as the conquistadors believed. It turned out that all that glittered was not necessarily gold - much of it was an alloy called tumbaga.

The metallurgical skills of the pre-Columbian Indians went unrecognized for centuries prior to the pioneering work of Dora M. K. de Grinberg and others in the past fifty years or so. De Grinberg, an Argentinian archeologist working in Mexico, doggedly followed tenuous leads to uncover ample evidence that the ancient Indian metalworkers were far more knowledgeable than had previously been supposed...

Archaic Period Point Recently Found in Plowed Florida Field.
Find and photo by JamminJack.

A couple days ago I posted a photo of an axe or tool and had it mislabeled as an Archaic point.  I went back and made that correction in the old post.  This is actually the Archaic point that was found the same day as the other item.  It measures about two inches and was among the finds that Jack and his buddy found in a newly plowed field.

Jack said, I did some research and found there was an outpost and old post office (1800s) nearby... 

Thanks Jack.

The Georgia governor despite a shelter-at-home order, opened the Georgia beaches, which like almost everything these days, was a very controversial move.

Here are today's Florida numbers from the Florida Dept. of Health dashboard.


You can use this link to access the interactive dashboard.

As you know the models depend upon data and assumptions, and the data, in my opinion is not very good.  There does not appear to be an overall highly consistent system and many states have not been reporting at all.

If you take the numbers from Germany, they have about a 1% coronavirus death rate, while the mortality rate for Spain and France is about seven times that.  That is a huge difference, which I believe must be due to measurement or reporting differences rather than population differences or differences in treatment.

Anyhow, you can keep up with the Florida statistics by using the FDOH dashboard.

You certainly can't say that coronavirus is irrelevant to metal detecting while the beaches are closed and we are under a variety of orders and advisements.

The Treasure Coast surf today is 3 - 5 feet and tomorrow is supposed to be 5 - 8 feet.

5/12/18 Report - Cocoa Beach. Jewish Conquistadors. First Americans. First Depression of New Hurricane Season. 80-Foot Wave.

Cocoa Beach Thursday
Photo by James F.

James F. sent me the following email along with the photos of Cocoa Beach.

Well, Cocoa Beach is an absolute mess after "re-nourishment" for metal detecting. Along with the tons and tons of sand come thousands and thousands of fragments of iron fragments from the dredging pipes. These are anywhere from a 1/8th-inch to 1/4 inch deeply rusted and highly conductive bits of Fe strewn, as my grandfather used to say, from Hell to breakfast, up the beach for literally miles.

What was once a very nice semi-productive beach is now a disaster for the next few years. The beach is nice from a tourists standpoint, but all but sterile from mine.

I've attached a couple of pictures I took yesterday, including a few iron fragments that now plague the beach here.



Rusty Iron Chip Like Those That Litter The Newly Renourished Beach.

Thanks James!

A few days ago I commented on the shiny pieces of metal that look like aluminum or titanium that I often get questions about.  One thing that I get just as many questiions about are small cob-sized iron flakes or chips like the one shown above.  You'll find iron flakes like this on many beaches, and the thing is that sometimes they turn black and can look very much like cobs.

Many metal detectors will pass them over and many will easily identify them as being iron, but if you have any question, as many people do, a quick way to tell is with a magnet.   If a chip like this sticks to a magnet, it is not a reale.

As James suggested, they are common after beach renourishment projects.  They come off of the large rusty pipes and other equipment.  Other beaches have similar iron flakes that come from older sources such as old erosion control structures, and some even come from various other rusting items.  On one treasure beach it was thought that a lot of these came from an old barge that was once used as a salvage vessel.

Conference presentations were dotted with colorful stories. Consider that of the covert Jewish Conquistador Alonso de Avila. He first enlists in the army of Hernando Cortes -- as a bookkeeper. In appreciation for accounting services rendered, he is then made the first mayor of the newly created city of Veracruz. But the glory is fleeting. He is arrested as a relapsed Jew by the Mexican Inquisition, accused of keeping a crucifix under his writing table and stepping on it -- a common but spurious charge, said Dr. Eva Alexandra Uchmany of the Universidad Nacional in Mexico, who told the story...

Below is a link for an article about the little known history of Jewish explorers in the New World.

The Americas are a big place, but the Native American group that first settled it was small — just about 250 people, according to a new genetic study.

These people, known as a founding group because they "founded" the first population, migrated from Siberia to the Americas by about 15,000 years ago, said study co-lead researcher Nelson Fagundes, a professor in the Department of Genetics at Federal University of Rio Grande do Sul, in Brazil...

By some theories the native or indigenous Americans may have been immigrants too.  Here is a link to the rest of the article about some of the first peoples of the New World.

An 80-foot wave recently set a record as the most massive wave of the southern hemisphere.

The first tropical depression of the 2018 season could be developing right now as Invest 90E.

https://www.aol.com/article/weather/2018/05/11/tropical-depression-could-be-first-of-2018-hurricane-season/23431627/


But locally we can't expect any more than a two or three foot surf for several days.

Happy hunting,
