Here is a fascinating find with an interesting story, but it isn't from the Treasure Coast.
"During field work near Jasło, a farmer found three gold bracelets tied with golden wire" - told PAP archaeologist and Krosno museum director Jan Gancarski.
I don't know if they are bracelets, but maybe.
In the list of dissertations that I mentioned yesterday there was a nice study of clay pipes.
Below is a figure from that study.
If you look at that illustration, it looks like that as pipes became more modern, they first got larger bowls and then later more upright bowls.
Here is the link for the dissertation and the figure shown above.
I once did a short series on reading beaches. One thing to watch is the sand of different grain sizes.
On the surface of the back beach and in the dunes, you'll see a lot of fine grain sand. The wind blows fine sand to form the dunes.
Around the water line there will also be a lot of fine grain sand, which is easily moved by both wind and waves. Fine sand can be washed up by very small waves. That is what we've been having a lot of lately, and that is why the beach fronts are building.
Fine grain sands also can be washed up the slope easily.
As you go out into deeper water, there will be more larger grain sand. Normally at around ten meters or so, you'll see a rapid increase in medium grain sand. Then when you get out around maybe thirty feet deep or so, you'll see more course grain sand.
When the water gets deeper, even large waves don't affect the bottom much. At that point you'll normally then see a predominance of fine grain sand again. The less easily moved coarse sand will pile up just before that where there is some winnowing from the waves, but not a lot - enough to move the finer sand towards shore or out into the deeper water.
Once you get into that deep water where the fine grain sand piles up again, mud will also start to settle out.
Of course there are times when you'll see different layers of sand piled on top of each other. In the high energy zone of the front beach and shallow water, big waves will move larger grain sands in and out and sometimes lay layer on layer.
If the waves are small and only fine sand is moving, like has been the case much of the time lately, other objects aren't being moved much either. Things will however get covered by the moving fine grain sand, maybe more quickly than you would think.
The highest energy zone lately has been in between where the waves are crashing and the shore.
Watch not only the water as it heads to shore, but also as it washes back. It goes both ways. And watch what happens to any shells or sand in that area.
Trigger points are important and vary for different types of items. I've talked about trigger points in the past. What I'll call the "drop" or "settle" points are also important.
Clay, for example, even though it is very fine, is difficult to dislodge but won't drop or settle out until the water is very calm.
This is all part of the picture that will help you to understand beaches and where to hunt.
I'll have to continue with that some other time.
I'll have more pictures of finds from the Capitana in my next post.
On the Treasure Coast we are expecting more days of calm surf.
That is not great for beach hunting, but it allows the salvors to keep on working.
