KEYWORDS:     GRAVITY SAND PATTERNS BEACH.TXT 

DESCRIPTION: 
              This unsual phenomenon occurs bi-yearly in the water and sand
              of this beach.  Strange attributes of an electromagnetic 
              phenomenon forms these grooved patterns on this beach containing 
              paramagnetic particles. Believed to be formed by gravitational 
              waves.

                                  INTRODUCTION







    
Three different formation timings.
After considerable analysis of the phenomenon I have found this to
not only a predictable bi-annual event but also cyclic for approximately
40 days before and after center dates.  A combination earth-sun and earth-
moon events.  Could occur almost any time of year, but most likely found
within the window dates.  Unpredictable as of yet outside the window dates.
A computer program has been partially developed as an aid.  Its completion
is expected in about 12 months.

NOTE:  It has been found the grooves often occur during high and low tide.
       This would sync it with the sun and moon.





  
    Fort Stevens State Park   46 deg 12 sec. N. Lat.   124 deg W. Long.
     

      On the beach on the Oregon coast at Fort Stevens State Park near Astoria
Oregon USA. The sand consists along with the normal sand particles a
black paramagnetic particle. This magnetic particle in sand can be found on
many beaches. If you run a magnet over dry sand the particle is picked
up readily and is about 1 to 5 percent (guessing) of the total particles. The
particles are most likely rust from the rusting hulk of the Peter Iredale, 
an English sailing ship which beached in a storm in 1906. The iron skeleton 
the ship is still there permanently stuck in the surf and sand.  The Columbia
river bar is known by sailors around the world as very treacherous. This 
area has claimed hundreds of ships says the maritime museum in Astoria.

     On this beach at the water line and during only certain times of the
year & day a phenomenon occurs. Best seen on a gradually sloping beach. 
During a receding wave when the water is only 1 or so inches deep these 
particles along with the standard sand goes into solution. Due to the
unique turbulence that occurs in this receding wave the magnetic particles
align them-selves on electromagnetic field lines.  The distance between lines 
(the wavelength) approximately *12-46 inches (Moon formation is less).
      The magnetic particles are attracted at regular intervals and form a dam
which also blocks the regular sand particles as well. When the water slowly
glides back out to sea a mound and rift is left in the wet sand. When the  
conditions are maximum, from the bottom of the rift to the top of the mound
measures approximately 3\16 inch or so, and are 1 - 1.5 inches wide. One
could stumble on them. The black particles are in the rift which by the water
action forms the mound with the regular sand particles. Its the same type of
mound and rift that is formed when water flows over a stationary shallow rod
(1/8 diameter or so) resting on the sand. This phenomenon  is not the
sometimes seen patterns on beaches which may look similar but have no mound
and rift.
      If one should doubt the magnetic interval attraction it can be seen
directly by watching the water very closely as it recedes and forms the line.
You will have to get your eyes within inches of the water as it recedes.
I swear they are drawn into place magnetically. Looking directly at the beach
after the wave has deposited the particles thousands of grooved lines may be
seen in the wet sand. If the tide is going out a signature record of these
grooved lines can be found.  This sand detector is many times more sensitive
than a coherer.



The pattern placed upon the beach resembles an interference pattern at times
and other times fairly uniform wavelengths. These grooves form intermittently
lasting for several hours and longer, wash away then reappear over and over
again until the event passes. The event lasts around 10-20 days appearing
then disappearing many times during this window. Sometimes appearing in 
patches or covering the entire beach.  When the phenomenon is at maximum
the wet sand becomes much softer (puffy) and more difficult to walk upon. 
Much like the before and after changes of rice when you cook it. 
The window opening will depend on your latitude as well as the date and time.

The gradual slope of this beach combined with the high concentration of
iron oxide particles forms a very sensitive detector based upon the domino
effect i.e. one very very slight interruption of the normal particle flow
within the water produces a domino effect.  Combined with the tremendous
number of iron oxide particles allows for the visual effect.  

The formation releases and disappears when the water flow becomes to great.
This can be seen clearly when the receding velocity of the water exceeds 
the attraction forces of the formation.     
This beach near Astoria Oregon has a heavy concentration of paramagnetic
particles. Traveling 60 miles south I found the particles had reduced a
significant amount. The grooves as well were much less pronounced.
The long beach area in Washington also has a significance amount.

 
Data shows that the phenomenon will occur on any salt water beach with the
proper conditions. It is a world wide event.

Another groove wavelength that appears there is approximately 3.5 - 5 
inches long occurs every 28 days. It is difficult to read and is below the
good resolution of the sand detector. This cycle may conforms to the lunar
positions and is extremely difficult to catch, occurring only briefly.

As the phenomenon begins to fade away the gap becomes wider and wider.
During maximum, the formation width can extend for miles, or as gaps widen
reduce to nothing. 



           

Question,  is this an attraction for the magnetic properties in the sand?
Probably not, as a magnet seems to have no effect on this formation.
Why?  It is probably an elemental attraction of the iron particles which
then because it is conductive is able to transmit this energy on the proper
atomic wavelengths that provides the carrier wave.

                             (window dates)

Main event occurs between June 27th and July 12th, and from December 24 -
January 12th approx.  You may need to spend several days to catch it in full
form.  








                              DATA ON PAST EVENTS



     The grooves are showing up at closer and closer intervals.
     37 days before aphelion the grooves were forming every 1.5 to
     2 hours. The beach sand between these intervals was for the most part
     smooth, without the grooves.



NOTE:  It appears the groove formation occurs often approximately 1 hour
       before low tide and 1 hour after high tide.



RESULTS of date 01-05-94 through 01-10-94:     Astoria, Oregon

        I witnessed a very dramatic appearance of the grooves forming in the
        sand on January 5th - 10th 1994 which I photographed and taped.
        A limited supply of photographs and VCR tape are available for those
        genuinely interested. These grooved lines have been appearing for
        years and are always attributed to wind or wave motion. Not true,
        these particular grooved lines only occur during specific times of
        the year!
        
        The grooves on the beach appeared as expected but did not gradually
        change in length as previously hypothesized. Instead they maintained
        several sets of wavelengths which occurred simultaneously. Usually
        lasting for several hours.

        Several wavelengths were witnessed occurring simultaneously. They
        often overlapped each other producing a less than perfect pattern
        of grooves on the beach.


        
        The groove formation as described occurs mainly during 
        the dates given.  Several other dates partway between these dates 
        will also produce the grooves.

        During the occurrence the beach groove formation
        appeared and then disappeared at irregular as of yet unexplained 
        intervals. Usually lasting for several hours apparently alternating
        sets of wavelengths. Having maybe 10 wavelengths per set filling
        the entire beach, quite an astounding sight to see at maximum.
        Often occuring at high and low tide which is also phased with the 
        moons cycle.  I am suprised I've not heard of this before.



*    Data shows that the phenomenon may occur on any ocean beach around the
world. Simply run a magnet through the dry sand (not wet) of your ocean beach
to see if it picks up any magnetic particles. The electrical properties
of the salt water may be a necessary ingredient. I have traveled down
the Oregon coast 60 miles from Astoria and found that the particles are 
still in the sand in reduced concentration and the phenomenon occurs there but
the grooves are less pronounced.  



It is easier to see the grooves when the tide is out so pick up
yourself some tide tables there at the beach if you plan to go to Fort 
Stevens State Park. Bring your umbrella, rubber boots, and warm rain gear.
The Oregon coast is known for its cold rainy weather. 

Sand particle size is extremely fine at this beach average .005 inch
diameter. The iron oxide particle is smaller yet. River sand definitely would
not work well. There are very subtle forces at work here.



How To Measure Wavelength:
Imagine large coils of spirals buried with in the sand at different angles 
with various amounts exposed much like a bunch of logs buried to different
levels.  You can only see the widths (the grooves) so the measurement is 
dependent upon how much of the coil is buried.  Sometimes the grooves 
extend 100's of feet maintaining their position from one wave to the next
as though something stationary was forming them.  
Something impeding the normal flow of water remains in position wave after
wave but slowly migrating until the forces pull it apart where by it grabs
hold in another nearby area.

Use the local tide table, the phenemonon often occurs at high and low tides.

The local high tide isn't caused by the moon (& sun) being directly overhead,
rather by the "dragging" action of these bodies on the oceans. When the slight
rise, but massive volume, of water is brought up short by a coastline, the tide
rises. Eventually the drag eases off (as the Earth turns), "letting go" of the
water which falls to a low. The shape of Earth's coastlines is what causes the
tides to be so erratic (consistent and forecastable for one location by
empirical means only!).
