7/6/20 Report - Tropical Storm Edouard. Beach Zones. Density and Specific Gravity of Things.

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

Yesterday I discussed liquefaction, which can occur on a beach under certain circumstances that cause sand to act much like a liquid.  I showed a couple photos of liquefied sand being moved by big waves.  Of course, most of the time that occurs near the front of the beach, but when the tides and swells are big, it can occur on the back of the beach.

Before delving more into the physical forces that move sand and other objects, this morning I thought it would be useful to mention the various beach zones of interest to the detectorist.  

Starting off-shore in the shallow water, there can be a sand bar.  That can be a good place to metal detect if there are a lot of bathers using the bar.  That happens a lot down in the Fort Lauderdale/Miami area.  It can be a very good place to detect for modern finds or what I call recent drops, but don't forget that the bar will move, and one side or the other, depending upon the direction the bar is moving, can be good detecting.

Inside of the bar, is often a dip, which can also be good detecting.  In fact some of my best detecting ever was in a cleaned out dip.  The dip can be full of sand and shells, but it can also be cleaned out down to bedrock, which of course is when the detecting can get very good.

On the beach front in the wet sand can also be good detecting, but it can also be poor, depending upon what is going on.  This area can be good or poor, depending upon a variety of factors, especially whether the sand is building on the beach front of eroding.  In either case, good water action can wash up good targets.  In the wet sand below the berm you might be able to find the coin lines or coin holes that I've mentioned many times.  They can also have other good targets beside coins.

The fourth zone is the dry sand area, which of course can be good if people have been using it.  Hunting the dry sand is very different from hunting the wet sand or water because the water does not do as much sifting and sorting there.  Detecting in the dry sand depends more on where things were dropped.  In the wet sand things gets sifted and sorted more, so you are often looking more for where targets ended up rather than where they were lost.  The water does however hit the wet sand area on some occasions and can definitely affect the distribution of finds.

The fifth zone is the dunes, where you will usually not be allowed to hunt.  Very old items will typically be buried a foot or more in the dunes, but when the water hits the dune face, items can be washed out and onto the flat beach.  

It can get a lot more complicated but those are some of the basics of the five zones.

---

We often talk of where you might find heavy items like gold.  As I've said many times, it is really not the weight that we are concerned with.  A ton of Styrofoam will float.  It is more a matter of density, rather than weight.  Other things are important too though, such as the shape of the object.  Bend tons of steel into the shape of an ocean liner and it will float.

Here are the densities of some of the metals you might find.  That helps explain why you can find aluminum when beach conditions are not very good, and why lead is a good sign if you are looking for beach gold.

Again, shape is also important.  Shape a super tanker out of steel and it will float.  Thin sheets present more surface area for the water to push around or lift.

Specific gravity is the density of an object relative to the density of a reference substance, usually water at a specific temperature and salinity.

Having a specific gravity of 19.32, gold is over 19 times more dense than reference water.

Sand has a specific gravity of somewhere around 2.65 to 2.70.   So being more dense than water it sinks in water.  There are a variety of other forces at work on the beach sand though, and the shape and constitution of the sands makes a difference too.

Notice the specific gravity of aluminum is very close to that of sand, so it is no surprised that you can find it in sand that is building on the beach.

Another generality is that it will take a lot more water force to move gold than either sand or aluminum.

If you understand these things it will help you figure out how things are moving and that will give you a better idea of where they might be found.

One of the things about gold rings is the relative lack of a flat surface area for the force of water to act on.  A copper coin on the other hand, will move differently than a gold ring not only because of the different density of the material but also because of the shape.  Likewise the movement of a zinc coin will be determined in part by the adherence of materials to the surface of a corroded coin.

That will provide some background for future discussions.

As I said yesterday, the National Hurricane Center map is starting to light up.  There is now a tropical storm :Edouard.  Edouard will not affect us, but there is a new system down by South America to watch.

6/30/20 Report - Calm Surf and Sandy Beaches. Treasure Coast Fossils. Fishing Artifacts.

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

Typical Sandy Treasure Coast Beach.

The Treasure Coast beaches have been accumulating sand for weeks now.  In the photo you can see where the waves are crashing on a sand bar and then washing sand in, during high tide, up on the beach.

Waves Breaking on Bar

If there is a dip inside the bar, the waves will break on the bar and then disappear if the dip is deep enough.  Where there is less of a dip, the waves will continue in.  You can easily look out and see where the dips are.  

Waves Breaking on Sand Bar.

The dip shown in the above photo had a lot of loose sand and shells in it.  The water was clear and you could see what look like waves of sand on the bottom.  It was far from washed down to bedrock.

Here is another small fossil vertebra found on a Treasure Coast beach.  It is in great shape and is very different than the snake vert.  I don't have any idea what type of animal it might have come from.

If anyone can tell me the animal, I'd love to know.  It doesn't look like the fish verts that I'm familiar with.

Here are a couple stone-age fish hooks found at an inland site that was once a lagoon.  Between 1932 and 2020 the land was drained.  You can see that the fishhook that was excavated before the land was drained is in much better condition than the one excavated from the drier earth.

As they mentioned on the Dino Hunters TV show, bones have to have the right conditions to fossilize.  After an organism's soft tissues decay in sediment, the bones are left behind. Water seeps into the remains, and minerals dissolved in the water seep into the spaces within the remains, where they form crystals.

1/13/20 Report - Beach Conditions Deteriorating On Some Beaches. Photos of Finds.

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

John Brooks Beach Near Low Tide Saturday.

The first and main thing I want to say today is that the beach conditions of the South Hutchinson Island beaches that I checked are deteriorating.  The surf is decreasing and the beaches are building.  I suspect the same thing is happening at the other beaches, especially any of those that were freshly cut on Friday.  I'm therefore dropping my beach conditions rating back to a 1.

This is the third time that the stretch from the condos to John Brooks has had five or six foot cuts in just a few weeks.  Frederick Douglass and the beaches immediately to the south were not cut nearly as much in that time period.

The two following photos show the sand that extends out in front of the beach.  That is where the sand from the cut ended up.

John Brooks Beach Sunday.

You can see the sand that extends out in front of Frederick Douglass beach below.

You can see a bit of a bar in front of Fort Pierce South Jetty beach now too.

Fort Pierce South Jetty Beach Sunday.

Fort Pierce South Jetty Beach Sunday.

All three of those beaches have a pile of sand in front of the beach.

I think Fort Pierce South Jetty beach is now back farther than it was the last time they renourished it.  Expect that beach to be renourished again before long.  They just keep pumping the money onto that one.

Terry Shannon wrote of a good day he had back around the beginning of the year and sent some photos of his finds.

Finds by Terry S.

Here is what Terry said.

… I found a modern 14 k ring, a bunch of coins all greenies, sinkers and then what I believe is ship wreck stuff pictured above. A small musket ball, a latch hook, a large bronze square nail that they converted to a rivet and some smaller old square nails. What I think is interesting is the silver ring.  This is the silver band when I found it and after cleaning.

Silver Ring Find Before and After Cleaning.

Find and photo by Terry S.

The ring cleaned up well and looks nice but it had to be lost a long time to have eaten up to this extent, the inside of the ring is as rough as the outside and it was very thin. I sent a picture to an expert and asked if it could be a ship wreck ring. He said definitely modern. My point is that it is often hard to determine what you have at times. 

Thanks for sharing Terry.

Terry also sent a photo of a half reale, which I plan to show as soon as I get around to it.   I also have some interesting recent finds from other people to show, but I'm getting tired now and will have to pick that up some other time.

11/9/19 Report - Wind, Rain and Some Cuts On The Treasure Coast Today.

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

John Brooks This Saturday Morning.

As you probably know, the wind blew all last night and it rained last night and much of this morning, including when I was out there.

In the photo above, the dark spots in the distance are two surfers.  There were some nice big surfing waves this morning.

John Brooks Saturday Morning.

The cuts you see immediately above are about two feet high most of the way.

There were some cuts at both John Brooks and Frederick Douglass.  The highest was about three feet, but most were two feet or less.

Under the white water is a sand bar that extends out twenty or more yards.  That is absorbing much fo the wave energy.

While it wasn't long until low tide, there were still waves that hit the bottom of the cut.

Frederick Douglass Saturday Morning Before Low Tide.

Frederick Douglass wasn't very different from John Brooks.

Frederick Douglass Saturday Morning Before Low Tide.

I only saw a very thin occasionally layer of shells in some of the cuts.

My photos could have been better despite the blowing rain.  I didn't take time to get good photos because I didn't want my phone to get too wet.

This was the first time I took the Equinox out in this kind of wet weather.

The sand in front of the cuts was still pretty mushy.

Overall, conditions didn't look very promising at these beaches.  I don't know about the Vero/Sebastian area.

The surf was supposed to be 5 to 7 feet today, and it did look like it got that big.

Just a few days ago I mentioned this is the time of year when we get some cold fronts coming through and that is what happened.

The surf is supposed to decrease tomorrow, but increase again later next week.

5/31/18 Report - Illustration Showing How Sand is Moved. Deadly Lightning.

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

Shallow Water Sand Spit

As you probably know, I spend a lot of time talking about how sand and other items move on a beach and in the shallow water.  That is critical information for any detectorist who wants to understand what is going on and where coins and things will most likely be found.  Today I'm going to try to show a developing sand spit.

In the above photo, there is a sand spit that runs from the bottom right of the photo to near the top center of the photo.  I'll outline that below.

Also there was water hitting the spit from two directions.  I'll also try to highlight that.

The predominant direction of the waves is illustrated by the blue line labeled A.  In deeper water that was the direction (from the upper right corner towards the center of the picture ) of all the wind driven waves.  As you can see things were different in the shallow water.

Near the orange circle, labeled D, there seemed to be a point where the waves bent and came up onto the sand bar as shown by C.  I watched this a little earlier before the bar was covered by water and waves were coming from about two o'clock and there were also waves hitting the bar from about 10 o'clock.  I wish I had my camera at that time.

The orange spot (D) would be the first place I'd check with a metal detector, however the dip was not nearly deep enough at this time.

The waves coming onto the bar from the left were getting bent and breaking on the sand spit.  You could see how the spit was bending the waves coming from that direction.

The following illustration shows waves hitting the spit from both the right and left.

Yellow Lines Indicate Waves Coming From Left
and Orange Lines Indicate Waves Coming From Right.

I came back the next morning and, as you would expect, the spit had changed a little.  The tide was lower and you could see more of the sand.  It had changed a little, but you can still see the waves wrapping around the point.

The water was funneling through the low spot and then encountering the slope, and having no where to go, piled up on the slope and the spit.  The waves appear to slow wherever it is shallower.  That causes the waves to bend.  There was undoubtedly also some water bouncing off the hump of sand at the upper left and bouncing back towards the spit.

Layers of Sand Built Up On Left Side of Spit.

Pshewww!  I finally got that done.  I spent a lot of time trying to upload a video but never got it to work.

1/29/18 Report - Recent Beach Conditions and Finds. Gold Rose Pendant. Lead Item.

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

Frederick Douglas Beach Sunday Near Low Tide

This is a good picture that shows a lot.  Notice the line of white water where the water is crashing into the front of the sand bar.  That line of crashing white water shows you where the sand bar is.  The sand bar extends out from the front of the beach maybe forty yards or more.  That means that any cobs being washed in from farther out would have to come over that bar or the bar would have to be moved.

Orange Line Is In Front of the White Water Line I Was Talking About.

Here is the same photo, but I added the orange line to illustrate what I was talking about.

John Brooks Beach Sunday Near Low Tide.

John Brooks looked smooth and mushy.

Blind Creek Beach.

Here is an area that produced scattered clad coins.  Not the cuts at the top of the beach and the slope.  This is not one of the shipwreck beaches.  I just stopped there and noticed the cuts and how the beach had been moved back and decided to pick up some of the the easy targets.

Small Gold Diamond Pendant Find.

Along with the clad was this nice little pendant that fits nicely with the thin chain I found the last time I detected.  The diamond chip is really small.

There was another beach to the north that was also cut back and produced scattered clad coins that I thought would have been picked up by detectorists the day before.

DB sent in the above photo and said this guy was "all in."  I need someone like that on my team to do my digging for me.

Gaylen C. sent these photos of one of his finds.

Here is what he had to say about it.

This was the only interesting find from yesterday [Friday]. Lead I am sure, heavy. I have found several pieces of metal in this small area that exhibit a similar appearance of smooth or flat on one side and a side that looks to me like it landed on a rough surface in a molten state. I'll include photos of a piece of iron that demonstrates what I think I see.

It seems I'm getting ads from people that have emailed me before.  I would guess someone somehow got access to the mailing list.  I'm not sure how I can fix that now, but if you are getting weight loss or other emails from me or some of the others from this blog, it is a hacking issue.  Sorry!

One thing I'll do if I send an email to you, I'll put From TG in the header.  Don't know if I'll remember to do that every time, but I'll try.

The tide is going to be only two to four feet, but we will be getting some decent tides.

The wind will be form the north Tuesday, but nothing exciting in the near term predictions.

7/27/17 Report - Webcams and A Few Tips On Hunting Modern Items In Shallow Water.

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

Sebastian Area Beach
Webcam capture submitted by Darrel S.

Same Beach Another Time.
Webcam capture submitted by Darrel S.

Darrel sent the above two webcam images of the same beach - one taken after a rain and the other when it was nice and sunny.  Darrel suggested using technology such as webcams so you can see what is going on and know where to metal detect.  You might not like metal detecting in the heat when all the sun-bathers are out, but you can check to see where the crowds are when you aren't on the beach.

I haven't talked about shallow water hunting for modern items lately.  I'll do that a little today.

Generally speaking, beaches and areas that have more people will produce more finds, but that isn't always the case.  It is a more complicated than that.  There are a lot of factors.  For one thing, as I've said before, some groups don't wear or carry much of anything to lose.  There are cultural differences and socioeconomic differences.   There are also differences between condo beaches frequented by residents who tend to take items off before going out to the beach, and resort visitors, who are less likely, for various reasons, to remove their valuables before going in the water.  Those are just a few examples of differences between various groups of people.

Young active people are also much more likely to lose valuables in the water than older cautious people.

In addition to people differences, beach conditions are important too.  When people are on a sand bar, items can be covered quickly.  When that is happening you'll have to find an item before it disappears.   How quickly it disappears will depend upon how the water is moving the sand.  It can take months or years for an item to be exposed again.

The dip in front of the sand bar can be good or not so good.  The dip will fill up at times and get cleaned out at times.  A couple feet of lose material can quickly accumulate in the dip covering up items like rings.

The following illustration shows a crude illustration of one beach area in front of a Fort Lauderdale resort that I used to hunt a lot. There was usually small dip and a sand bar in front of the resort.  On the other side of the sand bar was gradually deepening water.

The beach didn't change much over the years.  People always congregated on the sand bar in front of the cabanas and beach chairs.  Of course they crossed the dip to get to the sand bar and wondered off the sand bar at times, but most of the time the vast majority congregated on a small area on the sand bar.

Where do you think the majority of finds were made?

If you guessed on the sand bar, that is a good guess - but wrong.  And it wasn't in the dip, or on the deep side of the sand bar.

There was almost always a hot spot just to south.  I outlined the hot spot below (big grey circle). I could almost always find coins and jewelry in the hot spot even though I rarely saw people in that area.

Once in a while I would find a newly lost item on the sand bar where most of the people congregated, and occasionally something would show up in the dip, but usually I could find the good hot spot to the south of that.  The items in the hot spot were often discolored.  They were not recent losses, but had accumulated over time in that one area. That area was a pretty consistent producer.

My main point is that the best spot is not always were the most people go, although you will find items that were just lost there if you are quick enough.  Remember, sand bars move.  Sand is pealed away and the sand bar moves in one direction or another.  And dips fill and unfill.  If you happen to catch a dip that has recently formed and has been cleaned out deeper than usual, that can be a real hot spot too.  It would take me a really long time to try to describe how all of that occurs, so I won't try to do it now.

It pays to really get to know your beaches.  It takes time.  You have to explore a little, but once you know a beach, you can take advantage of that knowledge for months or years.

Don't forget that the sand is almost always moving to some extent, as do other items.  I've talked about trigger points and things like that in the past.

The history of a beach is important too.  Beaches go through phases.  They can be popular for a while, then became old and outdated and then be revived again.  Beaches that are not busy and active now, may have been in the past.  Coins and modern jewelry items can still be found years or decades after they were lost.  All it takes is for the sand to move.  I often hunted beaches that were not currently the most busy and popular beaches.

8/17/15 Report - Detecting With Beach Movements. Mystery Token. Marks On Silver Cross.

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

Markings On A Found Silver Cross.

Can anyone help me identify the markings on this silver cross.  If you can idnetify them please zip me an email.

The cross is about one and a half inches high.  I think it had a loop for a pendant.  The loop is missing.

Found Token

This token appears to be copper or brass and appears to be just a touch bigger than a quarter.  It is the same on both sides.

I'd also like help in identifying it.  Thanks.

The above illustration shows the shallow water area and a front beach.  I wanted to discuss detecting in the shallow water a bit today.

I put the orange lines in to divide off some areas.  From left to right, you have the deeper water outside the bar, then the bar, then the dip inside the bar, and then the slope.

You'll often read or hear people say different things like, Check the dips in front of any cuts.  Nothing wrong with that. It is good advice.  I'd check that area if it looks promising, just like I would check any area. The dips will be good sometimes, but sometimes not - depending upon what is going on. Its a very dynamic system and the best thing is to be able to read the flow.

It is never a bad idea to check any area.  But checking doesn't mean spending a lot of time.  Check and make a decision base upon what you see.

Checking can help you not only determine if there are any targets there, it can also help you determine how things are moving.

A couple of thing you might want to learn is what kind of material is in the dip and how much of it there is.

Some types of areas definitely produce much more than others.  No doubt about that.  No area produces all the time though.  And spots will change between hot, neutral and cold, and sometimes very quickly.

Any one of the four areas I mentioned above can be the best place to hunt. Those areas are always changing.  They change as the tides go in and out, and they can change whenever the wind and waves change.

A local thunder storm might not last an hour, yet it can change the situation substantially.  A thunder storm can pass by, whip up the waves and create small cuts in a matter of less than an hour.

There are changes that occur over decades, years, months, weeks, days, hours and even minutes.  The past couple of years, for example, we've been in a sustained period of small surf, and the beaches have changed, but mostly in one direction.   What we've been seeing is a bit unusual.  I've never seen such a long period of time with nothing but small surf.

Even within that time, though, there have been times when things changed significantly on a very short term basis.  One day the front slope was loaded with coins.  The next day that was entirely changed.

My main point today is that things change constantly.  Maybe not large changes, but changes that affect where you will want to spend your time.

The area outside the bar might be the place to be at times.  That would be when swimmers have been hanging out and playing on the bar before the bar moved in.

The bar will move in and out.  I like to check the side of the bar that is losing sand.  For example, if the bar is moving in, check the outside of the bar.

When the bar is moving in, if it goes on long enough, the dip will eventually get filled and objects in the dip will get covered up.

There are times when the dip is a good place to find things like watches.  That often occurs when there coarse shell sand and lose material filling the dip and the coins and similar things are covered up.

The dip can get really good when the front of the slope is cut away and things are dragged down into the dip, especially when the sand gets moved out to deeper water.

Recently on the Treasure Coast, and I'm sure neighboring areas to some extent, there has been very little movement and change.  Things have remained relatively stable for quite a while.  Despite how stable things have been there have been times when certain areas got hot for a short time.  There have been days when it was best to detect the wet beach and other days when the zone just in front of the breakers was good.

It is a dynamic thing.  Don't get stuck in a rut. It's more of a dance.  Get in tune with it and move with it.

I'll probably continue with this some other time - maybe tomorrow.

7/21/15 Report - Something You Need To Know For Water Hunting. Treasure Coast Waterways Cleanup. Junkyard Car Museum.

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

See link below for details.

I have been looking at lot of very extensive studies concerning the movement of beach sand.  Some involve institutions such as Woods Hole and the Department of Defense.  Some involve laying fields of state of the art sensors, both in the beach and out into the water.  Some of the studies cost hundreds of thousands of dollars and the reports are full of technical jargon and mathematical formulas.  Those studies are only concerned with the movement of sand.  While I am interested in the flow of sand, I am also interested in how other objects such as coins move, and those studies to not address that, although I can draw some conclusions about that from what they do find.  A lot of the studies found nothing much beyond what I've learned through personal observation, which pretty much amazes me.

If you use the following link and browse around that site, you'll be able to find some of those studies.

Here is a link to a nice animation of that site.   When you get to the site, click on the multimedia section to view the animation showing the moving sandbar.  You might want to repeat it a several times.

http://www.whoi.edu/main/topic/changing-shorelines-erosion

 (Animation by Jack Cook, Woods Hole Oceanographic Institution)

The location of sandbars can protect or endanger the face of the beach. As undertow drives sandbars away from the shoreline and further out to sea, waves break further from the shore. When sandbars are pushed closer to shore, waves break closer and run further up the beach. (From the Woods Hole site.)

I took some clips from the animation and added some things.  I added the two vertical lines so you could better estimate the position of the moving sand.  Orange dots illustrate coins.

In the first clip shown below, the sand bar is out and the currents are moving the sand in, but not the coins.  The arrows indicate the direction the sand is moving.

When the sand bar moves in, but the water velocity is not sufficient to move objects such as coins, the coins that were originally lost on the bar when it was out end up in deeper water (see below).  Objects lost in the dip in front of the sand bar (above) get buried, as shown below.

Compare the second picture to the first and note the relative position of the coins.  There are also times when the coins will move as well as the sand, but that isn't the situation illustrated here.  It is about trigger and drop points again.  Water force can be sufficient to move just sand or strong enough to move both sand and other objects.  Sand and coins can move at different times, and at the same time but at different speeds.

Sand bars are generally moving, sometimes very slowly.  As I've said before, items lost on the eroding side will be uncovered if they were previously covered, while items recently lost on the other side of the bar will get buried when the sand is moving in that direction.

Here are a couple more clips from the animation.  These show situations where the undertow moves the sand out.

When there is sufficient undertow, items as well as sand can be dragged out.  The clip below shows the bar moved out.  The bar has flattened some (below).  It could continue to move out until it looks very much like that shown in the first clip. When the velocity of the water drops the sand drops out of transport and piles up.

If you are aware of the sands position and how it is moving, that is a big step towards knowing where you'll find objects when you are metal detecting in shallow water.  Sometimes objects get uncovered and sometimes buried, and sometimes the objects are moved too.

Whichever way the sand is moving, objects are moving in some relation to that, again depending upon the trigger points and drop points of the sand and objects.

I hope the illustrations are clear and helpful.  I had a hard time getting them fixed the way I wanted, and still didn't get it exactly like I wanted.

 Nestled in a north Georgia forest, over 4,000 classic cars decorate 32 acres that have been turned into a junkyard museum. Owner Walter Dean Lewis' parents started the business in 1931 as a general store that also sold auto parts. Lewis grew the collection, which had just 40 cars in the '70s, over time...

Lewis stopped selling parts about six years ago, soon after realizing he could sustain the business more as a museum, charging $15 for visitors just looking, and $25 for photographers. He estimates that 95 percent of the people who come through the six miles of trails are photographers...
