Wabasso Beach Historical Shoreline Changes.

The USGS has an interesting web site that shows historical shoreline changes, including Florida. The snipping I posted above shows the Wabasso area.  If you look at the key and then the map, you'll see that back in the later 1900s the shoreline was farther out than it is today, but also farther out than it was in the mid-1800s.  It hasn't progressed continually in one direction or another, but has come and gone to some extent at various times because of both natural causes and beach renourishment.

There are a lot of interesting things you can find on the coastal hazards portal.  I didn't zoom in so much for the above image, but you can see that north of the inlet the shoreline is now farther out in the 2000s than it was in the mid-1800s, and south of the inlet, the shoreline is farther back in recent years than it was in the mid-1800s.  That is natural. You typically get accretion north of east coast the inlets and erosion south of the inlets because the supply of sand is cut off and that starves the beaches to the south.

If you look at the coast towards the top of the map, you'll see where the old St. Lucie inlet was.

I am showing these examples to highlight what I believe to be a very useful tool.  Here is another example.   The area is just south of Bathtub Beach.

You can see where back in the 1800s the shoreline jutted out.  Now the shoreline is much farther back than it was at that time, but it is more seaward than it was the the 1900s.  That is probably due to beach renourishment.  You can also see the rocks at the present shoreline.

Too bad they don't show us where the beach was in 1715.  That would be very useful.


Here is another example from the coastal change hazards portal.   This one (below) shows the probability of inundation and overwash from Irma.

You'll have to visit the site and take a closer look at this one with the key etc.

Another part of the same site shows that maria affected the South Carolina and North Carolina shoreline the most.

Here is the link if you want to really explore that web site.

People are acting like the surf has gone smooth.  It hasn't.  Look at this.

And Sunday the swells are supposed to be more northerly.  Something good could happen yet.

A lot of people got excited when they heard there was going to be a hurricane.  Everybody got ready.  Then a lot of them went out and were disappointed. 

How many times have I said, it doesn't take a hurricane.  I recently posted about the 1984 Thanksgiving storm.  That was no hurricane, but there was a lot of treasure found.  I'm getting the feeling that a lot of people are starting to snooze after all the hurricanes passed by.  That might be a mistake.  There is still a lot of good surf predicted for the next week or two.  If it wasn't for the very high surf we've had lately, the surf that is predicted now would be getting people excited.  I'm just thinking that people might be giving up too soon.

I got a report from Kevin K.  Here is what he had to say.

I went to Frederick Douglass and John Brooks beaches yesterday to hunt, using my ground-penetrating radar machine and my Bounty Hunter Landstar detector. The surf was, indeed, running 5-8 feet with many breaking on the first reef - wish I’d had a surfboard! As you said in yesterday’s blog, it looked like new sand had been added all the way up to the permanent dune, and I did not get one hit on the metal detector, although a lot of false readings on all-metal mode. Those readings must have been mineralized sand, as the discriminator mode never showed anything. The radar machine did not show any deep targets down to 10 feet, although up near the dunes some areas showed disturbed sand as deep as 5 feet...

Thanks for the report Kevin.

Kevin also lost a gold wedding ring in the process and is hoping it can be found.  Here is how he described that.

Somehow I did manage to lose my gold Claddagh wedding ring probably near the Douglas pavilion or in the parking lot of the street north of the Brooks Beach entrance-so if anyone finds the treasure I left, I’d like it back!

Let me know if you find Kevin's ring,, and I'll hook you up for the return. 

Kevin might also be able to do some ground-penetrating radar for you.  His business is Underground Discovery, LLC.

That is all for today.

Happy hunting,
