| One to two foot cut on the Treasure Coast this morning. |
This morning near high tide the same cut that I showed yesterday was now only about a foot to a foot and a half high. The waves were hitting this beach almost directly at a ninety degree angle. That won't cause much erosion. Instead the water just washes in and out, rounding off any cuts and leaving a bunch of mush at the foot of any remaining cut.
I made a short video that shows what happens when the waves hit the beach at too much of a ninety degree angle. Unfortunately I couldn't get it to load today. Maybe some other day.
The photo above shows the same spot I showed yesterday, but now the cliff face is only about half as high as it ws yesterday.
The seas were rough today, reaching from five to seven feet but will be decreasing tomorrow. However, the wind and waves might have a more favorable angle tomorrow.
Still there were some beaches that showed no erosion at all this morning.
The water did get a little higher than yesterday at high tide, but barely touching the foot of the dunes in some places. It didn't get high enough to significantly erode the dunes.
There were some weathered clads in front of the cut in the mushy sand.
Rafael is predicted to become a hurricane, but will stay pretty far out in the ocean. I'm not seeing any signs of much if any beach detecting improvement in the next few days.
Low tide on the Treasure Coast today will be around 1:30 PM.
John L. emailed the following to me.
Not long after tropical storm Issac, I found 33 coins (including 13 quarters dating from 1974-2001) in a coin hole no larger than 8x8 feet just north of a large pile of rocks (a setting just as you have often described).
I thought this might make for a good topic for the next survey; i.e. "what is the most coins found in a coin hole"?
In addition to a future survey question, I thought the topic was interesting enough for a little discussion.
How about some of you? What is the best coin hole you have detected?
If you are new to this blog, I've defined and discussed both “coin holes” and “coin lines” in this blog in the past. To give the short description, coin holes and coin lines occur either on a beach or in the shallow water, where coins have concentrated over time due to the sifting and sorting of the waves. The primary difference between a coin line and a coin hole is the shape of the area in which the concentration of coins are found, although there are other differences as well.
John describes a coin hole of roughly 8 by 8 feet in which a very good concentration of coins were found. He also points out another feature (rocks), which probably played a roll in trapping and concentrating the coins.
Some spots where coin lines and coin holes form, will refill on a recurring basis. I've seen coin holes that I was able to mine time after time and they would often refill.
I once worked on coin hole for four hours and found over $20 in quarters alone, along with a lot of other coins and gold items. I came back and worked that one for another four hours the next day, and although I don't have my records for that, I found about the same amount the second day, after which a front came through and the hole disappeared. I don't know how big the hole was. I didn't get to finish it before it disappeared.
One coin line yielded 15 rings in a period of four hours. That coin line was probably 30 or 40 yards long. I don't have a coin count for that one.
There are also times when there are what might be called gold holes. Gold holes will sometimes hold several pieces of gold jewelry items that have accumulated in a small area, but few if any coins. Most good gold holes will also contain a few coins, especially quarters. Lead sinkers will also often be found in gold holes.
From my experience, in coin lines and coin holes, quarters are more closely associated with gold items than other coins. Pennies, especially zinc pennies, often define the outer boundaries of a coin line, while quarters tend to be closer to the center and down the slope more when you are on the beach. Again, the gold is not always but is frequently nearer the quarters than the pennies.
That is a good topic. Please email the size and coin count of coin lines or coin holes that you have found, along with any other interesting facts, such as rocks or trees etc.
If you use the blog search box, you can find old posts on coin lines and coin holes.
Happy hunting,
