Captain Jonah and the boys of the Capitana are hitting the gold again. Captain Jonah said, Here's a earlier 8 escudo from the season congrats to Larry B. Aboard the Capitana. One thing is it isn't from 1715.

Naturally we often talk about the 1715 Fleet. There is so much of it out there. But there are other treasure wrecks along the Treasure Coast too.

Congratulations guys! Always love to see your finds.

I've talked a lot about the movement of sand in the past. I haven't done that for a while. I received a question yesterday that prompted me to talk about that a little today.

In calm weather waves break close to shore and the sand moves in and onto the beach. Each tide more sand moves onto the beach.

When the sea is rough, sand gets carried out and away from the beach.

I borrowed the above illustration from somewhere long ago and can't find the source right now.  I think it was from some university class notes somewhere rather than a published book.  Maybe I'll find the source again.  

Illustration Showing Accumulated Protective Layer of New Sand (Red)
I just made this illustration.

In the above illustration there is a protective layer of unproductive new sand covering the front of the dunes, the front beach and the sand in the shallow water. Any of those layers can get eroded down to expose more productive coin-bearing sand.

As I've explained in the past, sand that is moved in during the most calm weather. like we've had most of this summer, will not contain coins or much of anything other than sand. The force of the water simply isn't strong enough to move much else.

In the above illustration I circled one very important area - the area right in front of the beach. When the water gets rough, this sand can get moved out into deeper water, thus exposing coins and other things.

Also, don't forget the importance of the north/northeast seas that result in strong north to south currents that slice away at the sand on the beach and carries it along with the longshore drift to the south. The result is that the protective sand that covers things like coins is carried away so they can be washed up onto the beach.

If you don't follow any of that, I recommend searching back through old posts and reading some of those.

Experts discovered stones beneath San Antonio’s Alamo Plaza last week that could be associated with the main gate of the 18th century Mision San Antonio de Valero, as the Alamo Mission was originally known.

Here is the link for more of that article.
Thanks to Dean for that link.
They recently recovered the tip of a Mexican sword while excavating at the south wall gate of the Alamo.
The artifact is believed to be from a sword issued to a non-commissioned officer in the Mexican infantry and dated about 1835, according to Nesta Anderson, the lead archaeologist on the dig. It could have been used in the famous battle for the Alamo in 1836 or in construction along the southern wall, she said at a news conference at the site Thursday morning.

We now have Tropical Depression Six, however as I suggested a few days ago, it looks like it will head north before coming close to us.

Predicted Path of Tropical Depression Six.

Expect a little bump in the surf tomorrow.  Something like maybe three feet.  Then not much again.

Happy hunting,
