 I did find some interesting iron targets on the intercoastal side of one beach, but i don't think they are super old!

Has anyone worked out a time-of-decay relationship for iron in seawater?  Is it impossible that those are from the 1715 Fleet?

I've noticed that the older, cork-lined crown caps are quite rare in my area.  I interpret that to mean that they've corroded away.  Since they were common in the mid-60's and earlier it seems that 50 years is about their limit in our ground with moderate annual precipitation (40+ inches ~ 1+ meter).  Another possibility is that they're still hanging in there but have rusted so badly that they just TID non-ferrous.  That still doesn't give them a long life since next step after that is crumbling back to nature.  Nails (which are thicker) last longer, particularly the square ones.  I suspect the reason for that is that square nails are of a different alloy than the typical modern style round cross-section nails.

In our dry USA Western soils I assume crown caps fare much better, to the dismay of detectorists there....

Wonder if the smaller ones were some sort of pins for rigging ropes. They look like some sort of eye loops that might have been fastened to decking.

If your hunting iron you can always get a PI and dig everything from bobby pins and up ?

GB,

    I found those in Stuart, which is well South of the 1715 beaches! But they could be part of an old fishing boat, or something, being where i found them!??

Great way to start Fall here!

Great pictures Joe D.; if you don't mind me asking where are those beach front rocks in the picture? Walton?

This fall has been disappointing and you have not missed much. We need min two days of moderate N NNE winds. The coastline runs NW-SE so even NE winds are straight on shore and we need min. 4-6' high surf as well.

I use the surf reports forecast. Happy Hunting!

FloridaSon,

   This is where the pictures are from! Cool place if you haven't been before! The rocks are the only reason this place is still standing! Or else it would have been blasted into the Indian River long ago! ??
