10/8/17 Report - Knowing Your Beaches: Classifying and Categorizing for Metal Detecting. The Blog Poll. Hurricane Nate.


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

Hurricane Nate caused a lot of flooding and road and beach closures in the western Florida Panhandle.  There is a storm surge and still high waves.

I wanted to talk a little about the blog poll today.  I had a lot of information entered and lost it so I'll start over.    I'll do a little now, and if I have the patience, more later.

The current blog poll should provide some good and interesting information.  It will unoubtedly give us some good insight but also leave some unanswered questions.  Already the early responses made it clear that cobs are found other places than on the Treasure Coast.  That isn't surprising, but those of us  who live here focus so much on the Treasure Coast, that we might not think much of hunting other areas of Florida and the world.  It is always fun to travel and detect new places.

People have reported cob finds from both other areas of Florida and areas outside of Florida.  As you probably know, cobs can be found on the West Coast of Florida, Canaveral area, West Florida, and many other places.  I have regular readers from North Carolina and other states and regions where cobs are found.

I am hoping that you will take the little time necessary to respond to the poll, because when we have good information we all win.  You don't need to be afraid of giving away your favorite spot.  The poll covers five years and does not tell anyone what area is hot now or next week or next year.  And we all know that things change.

In retrospect, I wish I would have specified a longer time period than five years.  Hurricane Sandy was about five years ago, and I'd like you to include that time period.  Since then beach detecting conditions on the Treasure Coast have been poor more than not.

If you read this blog and get anything out of my free work, I hope you'll make a contribution in the form of your response to the polls.

There was an 8-mile stretch of beach that I detected frequently in the 1990s.  I looked at it as consisting of 15 different zones.

The first zone was a very narrow swimming beach where a lot of people crowded on nice days.  It produced a lot of good quality jewelry on a regular basis.

Moving north and going around a bend was what I considered zone 2.  This was a longer and wider shallow-water area that produced significantly less jewelry, and the jewelry there was of a significantly lower quality, even though the area was still in the same park.

Moving farther north was zone 3 - a dead zone.  Almost nothing came out of there.  It was in front of a condo, but it seemed few people from that condo ever went outdoors, let alone swimming.

Zone 4 was the next area, which was in front of a condo or resort that was closed.  The beach there produced relatively little, but on a few occasions when the beach eroded, you could find good coin lines with a little jewelry on the eroded slope.

Zone 5 was a private beach club.  A lot of people went to the beach and swam there.  I found less there than I thought I should and always suspected there was somebody else that cleaned that location regularly.  I wouldn't doubt if it was some of the staff of the club.  They didn't like me being there and I once was told I couldn't detect there, but I knew better.  I called the county offices and they told me the public had every right to use that beach back to the erosion control markers. Public tax dollars maintained that part of the beach.

Zone 6 was another dead zone.  One or two nice pieces came out of the shallow water even though it was covered with sea grass and had  lot of aluminum junk.

Zone 7 was around a sand spit that extended out into the shallow water where a lot of boaters parked.  The interesting feature of this zone was the remains of a wreck  under the beach where the sand bar joined.

Zone 8 was a good hole.  It was in front of an active high-scale resort.  Not as many items as in zone 1, but higher quality.  Some very good finds came from there even though there was known competition.  I believe that it was resort staff.  A fellow stood and watched me working the water one day and left cursing when he saw me dig a gold chain in very shallow water.  I could tell that  a lot of my finds from there were not the easy finds and were things somebody could easily miss.

Continuing north some more, next was zone 9, another condominium.  This one had more active people and produced a few good finds.  It was much better than the other condominiums but not nearly as good as a few of the other zones.

Zone 10 was long dead zone.

Zone 11 was a big public park with a huge shallow swimming area.  This swimming area would produce very few coins but almost always a piece of gold or two.  It was visited by more detectorists than any other zone other than possibly zone 1.

Zone 12 was at the north end of the parking areas.  Most park visitors stayed in the main swimming area just south of there.  Zone 12 was a relatively small area where it seemed people parked before the paved parking was put in.  This area produced coins and jewelry dating back into the 1800s.

Zone 13 was larger and had a much lower concentration of coins.  The quantity of finds was low and the quantity was no better than average.

Zone 14 was  rock outcropping that was usually covered by sand, however after one storm there was a virtual carpet of older silver coins and jewelry there.

The next zone (zone 15) was a small area where people in the past evidently parked along the road and visited the nearby small beach.  The coins there were generally mid to early 1900s.  They were usually very heavily corroded.


I have a number of reasons for going through the list, but mainly wanted to give some idea of how you should get to know your beaches as potential detecting sites. 

I might expand on this some other time in the near future..

Sunday the wind is from the south and the surf is down again.  There is a nice high tide today though.

Happy hunting,

10/7/17 Report - Difficulties of Dating An Artifact: Florida Dugout Canoe Find. New Poll. Hurricane Nate. Sand Monster.


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

Hurricane Nate
Source: nhc.noaa.gov

Hurricane Nate is not going to affect the Treasure Coast but might affect the Florida Panhandle.

Bathtub Beach is eroded and they are talking about bringing in more sand next week.  It seems like that is a continual thing there.  I talk about obstacles to sand flow like rocks and sea walls that cause localized erosion.  The houses to the north of Bathtub Beach cut off the sand flow.

Remember what I posted yesterday about renrourishment sand.   Depending upon various factors, it could have something good in it.

The winds have turned southerly and the surf is now down to 2 - 4 feet.  There will, however, be a good high tide.

The dugout canoe found in Cocoa by Randy Lathrop back in October was thought by some to be very old.  After closer examination, its age is in question.

A Florida Division of Historical Resources archaeologist inspected the 15-foot log vessel, and radiocarbon dating results were released Thursday. The tests determined there is:
• A 50 percent probability the wood used to make the canoe dates between 1640 to 1680.
• A 37.2 percent probability the wood dates between 1760 to 1818.
• An 8.6 percent probability that it dates to 1930 or later...

"The canoe has some interesting features, like the presence of paint and wire nails, that indicate it may have been made in the 19th or 20th century, so this adds to the mystery," she said...
Or, perhaps the canoe was made in the 1600s or 1700s, saw use for many years, and was modified over time..
"Florida has the highest concentration of dugout canoes in the world. We have more than 400 documented dugout canoes in our state. Each canoe is important in that it adds to our database and helps fill out the picture of how people used these canoes over thousands of years," Revell said...
Here is the link for the complete article.

Of course we want to learn the age and identity of finds, but it can be difficult or impossible to do with precision.  Even with readiocarbon dating you are left with probabilities, not a precise date.

One tricky thing we often neglect is that an item can be from widely disparate age ranges.  Part of an item can be older than another part, and then it can be used for years or centuries and modified, repurposed or remanufactured.

It is especially difficult to put a date on some barely identifiable clump or something without any context shown in a photo.

Even coins that give you a mint date don't tell you when they were lost.

I posted a new blog poll.  This one should be interesting.  I'm trying to determine where treasure coins or cobs have most often been found during the past five years.  Answer to the best of you recollection.  Thanks much!

You might find this interesting.  It is about a real sand mover.

The other day I mentioned a few older finds I made in renourishment sand.  Joe D. wrote in about metal detecting renourishment sand.  Here is what he had to say.

I'm glad you brought up the subject of how important the original location of the renourshment sand source is when surveying beach locations to detect, since that is what many of us end up detecting when there is little erosion going on. 

I wanted to give you a few examples of the locations of the last several I've had knowledge of and detected often as they were put down and subsequently eroded out.

The most recent of which was the beach South of Jupiter inlet, from the inlet to the end of the public beach. The sand source was a little inside the inlet in front of Dubois Park. An area with quite a bit of history, but not the original inlet location, which was a little south. Nevertheless, my thinking was that it might turn up some good stuff if it was not overly filtered for size; which I believe it was based on the composition after the fact. I have found nothing old or fossilized in this stuff, which looks more like shell rock than beach sand, and barely moved at all compared to the regular beach sand from when Irma came through. 


On another renourshment project in the South end of Palm Beach a year or so ago, they dredged from offshore about a quarter of a mile and were nice enough to dump the larger filtered items in a nice pile in Phipps Park for a couple of months. It was all shells and rocks and anything of size that didn't meet the sand size specs. I found many piece's of copper sheathing and several brass spikes over that period. And there were many shell collectors there all the time.

Another two renourshment projects in Palm Beach at the main beach were not productive. The most recent came from directly off shore, which is now gone. And the one before that was trucked in from a sand pit on the other side of Lake Okeechobee! They, and us, paid big bucks for that one, only to watch it wash away in a year or so.

One of the most important things I learned about this process is that the sand is filtered for grain size, and I guess, secondly if at all, is quality of sand, which probably differs from each location based on the governing body, and how much it will cost, and how much the state will cover. If you can find out or get access to the filtered material before it is hauled away, that is where a lot of the good stuff is.
If you have anymore knowledge to add, it would be interesting to hear of any other observations besides my own.

   
Thanks. Joe D.


Thanks for sharing your experiences Joe.  I hope others will as well.

Joe brings out some important factors: the source of the sand and the filtering.

Just a few days ago I mentioned how I found a WW II cap badge in  renourishment sand just south of the Fort Pierce inlet.  That wasn't from the most recent renourishment project.  It was one or two projects before that, but the point is that good old stuff can be dumped on a beach with renourishment sand.  At that time, there was also a bunch of garbage in the renourishment sand, including a lot of mangled aluminum cans.  They didn't bother to filter a lot of the garbage out that time.  

Renourishment sand can be tricky.  There can be a variety of layers form different times that get mixed together in no discernible order.

There is one place on the Treasure Coast where new sand was dumped a year or two ago.  It is a fine white sand, and near the dunes they planted sea oats in it. Under that sand is a thick layer of sand from fifty or more years earlier that was dug from in front of the beach and dumped on the dunes and beach.  That time they dug down through sand that is recent and down through sand that contained millions of years old fossils.  When it was dumped on the beach, it was not dumped in order, but spread out so that Styrofoam cups and plastic garbage bags were mixed together with ancient fossils.  Despite the mixing you can easily tell the difference between this sand with older items spread through it and the most recent renourishment sand.  The point being that renourishment sand can be  either homogeneous or a varied mixture.

I tend to do a little sampling of any renourishment sand to see what might be in it.

Observe the different types of sand that you can see on a beach.  If you carefully observe the sand, you'll be able to see how it is moving.

Notice when different layers are exposed.  Different layers can be associated with different types and ages of finds.  The sand can tell you a lot about where you should spend your time.

Tell me about your finds and experiences with detecting in renourishment sand.

A breathtaking hoard of ancient Roman bronze artifacts, described as the first of its kind in British history, has been unearthed by a pair of metal detector enthusiasts.

The 4th century hoard found by Pete Cresswell and his brother-in-law Andrew Boughton in Gloucestershire includes a sculpture of a "licking" dog never found before in the UK.

The licking dog is an example of a healing statue, and may be linked to a Roman healing temple at Lydney, near the Forest of Dean...

Here is the link for the rest of that story.

There will be a nice high tide today.  The surf will be decreasing a foot or two.  The wind will be shifting to a more southerly direction.

Looks like Nate will be a hurricane, but won't affect us in any significant way.

Happy hunting,
