9/12/11 Report - Recent Beach Erosion Caused by Rain

Rain Erosion on the Face on a Dune Extending Down to the Flat Beach.


A couple of days ago I mentioned that wind and rain can erode the dunes too. I found this example of erosion caused by a recent rain storm yesterday.

Notice the gully at the top of the dune, running down the face of the cliff and onto the beach. Always check gullies, big or small, for items that might have washed out.

Check areas like this very thoroughly visually as well as with your detector. The rain will often move enough sand to expose items even in flat areas.

Detect any eroded area, the gully, and especially the area at the foot of the dune where materials might have fallen or been washed down.

Very carefully look for any and all sign of uncovered or partially uncovered objects.

On a cliff, the dune can get so saturated that the face of the cliff peals off and piles up at the bottom of the dune. That was happening here.

When that happens thing will fall out of the dune and end up at the toe of the dune, sometimes rolling a few feet away from the dune, but there will be other things that then stick out of the dune but do not fall. That means you should carefully inspect the face of the dune too.


Another Areas Where the Rain Washed Off a Layer of Sand.

Notice the newly exposed roots. That indicates that sand that has been in place long enough for the roots to grow has been eroded. Always a good sign.

Here is another shot of a rain-washed area not far from the one above. This area ha smaller gullies and hardly and no cliff to speak of. It is always worth checking any newly washed areas both visually and with a detector anyhow. Besides being exposed, things can get caught in any dips or creases.

I saw detectorists at the beach yesterday, but they didn't even look at these areas. In my opinion the washed dune areas were the most promising places that I saw. Some of the cliffs were higher than the ones in the photo and a good bit of material fell off the face.


The waves were higher than I expected yesterday morning. There were a lot of surfers taking advantage of that.

It was hard to work the low tide zone because of the waves, but it might have stirred some things up for some other time when it is easier to work. It is also a full moon now and the high tides are fairly high.

Here is a link showing the waves and some surfers on the Treasure Coast yesterday.

It looks like Maria will stay pretty far away from us. There are no other major storms to be concerned about now.

The surf web sites are showing one or two foot seas for the next few days.

I don't expect any significant change in conditions.


A couple readers confirmed that the ceramic tube I asked about a few days ago is an insulator. David S. sent me a link to a Wikipedia article on tube and knob wiring which shows the use of those tubes along with other insulators (knobs). The tubes are the ones going through the beams. I've found some of those other insulators as well.
