SD Arrows: What is it?
|
|
First area is in Bahrain- Saudi Arabia, off the coast. A series of underwater 'arrows' that seem to be aligned to true North. All are pointing in the same direction and many are located a good distance from the shoreline on the adjacent sand bars. Some of the 'arrow' features seem to be buried by sand.
This first download includes 24 placemarks of the 'arrows' and a few linear features.
Does anyone know what these underwater features could be?

Linear features in Lake Okeechobee. I am stumped by this long linear feature and the adjacent linear features.
Any ideas?

How bizarre!
I cant see its of any use to shipping.
Very odd!

If you extend the line north, it appears to go between the shore and an island. Although most have been destroyed, Florida is covered with the remnants of ancient canals. This may have been one that eventually flooded into a lake as sea level rose.

I wonder who could be responsible for those canals, if they are canals?
I saw what you are referring to the first time I looked at this site. I thought it could be modern, but I'm not sure after hearing about a story by Frank Hudson about possible ruins under Lake Okeechobee. I will try to buy that book and post some info on the blog. Thanks for your input Rob!

Hi, SatAm,
I believe these are fish traps, similar to the ones shown below.
See this post for a discussion on similar structures in Korea.

Thanks for the reply. Would they have created the fish traps so far offshore? In other words are they modern or potentially old since some of them seem to be so far offshore?

Archaeologists Unearth 1,700 Year-Old Canal System Near Lake Okeechobee (Florida)
Sun- Sentinel ^ | 6-6-2002 | Rhonda Miller
ORTONA – Archaeologists on Thursday said they have uncovered a sophisticated 1,700 year-old canal system and a huge pond dug by ancient Indians near this tiny town, located west of Lake Okeechobee.
The canal site is so important that it could rival the discovery four years ago of the mysterious Miami Circle ruins near downtown Miami, one expert said.

SD What is it?Underwater parallel features, NC
|
|
Parallel features off the coast of NC. A distinct edge can be seen of what looks like a submerged, Carolina bay. The area within this 'bay feature' contains parallel features that seem to be equidistance apart.
Anyone know what could cause such features?

Re: What is it?Underwater parallel features, NC

The 'parallel feature' line is probably the flotsam and jetsam line that is always somewhere offshore. This is where the coastal currents and the open ocean currents meet, where the green (or brown) water meets the blue as the fishermen say. This is where all of the trash that empties into the ocean, and is thrown or lost overboard meet and mingle with the seaweed and is a bonafide fish magnet.

Re: What is it? Arrows
|
|
SatAM17,
probably in the past, the Gulf was not so deep as nowadays - the streams and sediments could had covered other arrows that pointed navigators to north. Seems to be a kind of direction to follow, a way to avoid wrong path.
How was it made? Who did it? This forum will call others attention.
Good eye! Congratulations.

Re: What is it? Lines

Take a look to the west-southwest and you'll find more that are not aligned with true north.
I think they are some sort of tidal traps as someone stated earlier.

Re: What is it?

They are fishing nets anchored to the sand in shallow water. The arrow shape funnels the fish into the end where they get caught up in the nets by their fins and gills. Once a day the fishermen (if they can be called that) come along and harvest the fish.

SD What is it? Lake Okeechobee- Part 2
|
|
Linear feature close to the shoreline with waves diverting around this underwater line.
All the survey maps indicate this line is not a modern construction.
See original GE images here
The original GE images have been almost obliterated by new, repetitive image data to the left of the line. Fortunately the images were saved before the line was obscured with the new data that seems to be inaccurate and repetitive along the whole strip. Wish someone would clean that up...

A series of unusual features can be seen in this placemark tour off the Florida keys near the city of Marathon and Knights Key Channel.
The features consist of underwater linear features, unusual patterns, and circular features that are very unusual and anomalous.
Does anyone have a clue what has caused these features?

Pipes?
|
|
It seems to me that these fishnets would have apeared dark on an airial photo, and not light like they do. On the airials it looks like they are lines of clear sand under the water, unlike most of the area where it is covered by sea weed or something.
Couldn't it be pipes. there is a big white area too, maybe there use to be an oilrig there and there use to be oil pipes there, so now there is just clear sand.?

Re: SD What is it?Underwater parallel features, NC

My Wilminton roots go back into the 1800's.
My father told me that he once saw some old aerial maps of Wilmington that showed the city and surrounding area sitting in ancient meteor craters such as the 'Carolina Holes' off of Chalreston. This could very well explain the features off the coast of Masonboro Inlet.

Re: SD Arrows: What is it?
|

Yes, these are simply tidal fish traps. there are more along the west coast at a different orientation.
they are modern, as in they are currently in use by local fishermen from the coastal villages, but ancient and traditional in design, simply wooden stakes driven into the sand-bed and the suspended nets form a funnel that fish can swim into but not out of.
As for the lines, they seem to be just natural rifts or channels in the bed.
This water is very shallow, possibly less than 4 feet at low tide.

SD: What is it? Florida Marshland circles
|
|
I have contacted an archaeologist about this area with no reply so I'm hoping someone can tell me if this is a modern or ancient attempt at agriculture. The placemark takes you to a marshland region on the Southern tip of Florida that contains equally spaced circular features. What's so interesting about this area is the fact that similar circular features aligned in rows have been sighted underwater near the Florida keys so I'm thinking if it's ancient, it could be a potentially very old site. I've also spotted the same features in the deserts of Africa and I plan on posting these to the site soon.
All comments are most welcome!

Re: SD What is it?Underwater parallel features, NC

Given the concentric circle that this pattern displays around inlet in-between Carolina Beach and Masonboro, the normally cloudy water around Carolina beaches, & the proximity to the Cape Fear River, I would surmise that what you're seeing is just the water currents from low-tide.

|
|
Re: SD Arrows: What is it?
|
|
Common throughout the gulf region. They are fish traps, basically walls of netting supported by poles which guide the fish to the arrow head where a holding pen with wedge shaped entrance keeps the fish trapped but alive untill the fisherman can collect them. I surveyed many of these areas in the 80's & 90's by boat and ruined several propellers hitting the damned things at high tide when we couldn't see them properly!

Re: What is it?Underwater parallel features, NC
|
|
Have you never been to a beach before? Those so call "Underwater parallel features" are nothing more than waves. And as for the brownish circle looking shape, that is where the intercoastal brackish water meets the ocean water at low tide. Fisherman sometimes call this line a weedline or foamline because that is where seaweed and trash collect.

Circles on Browns Island
|
|
The Circles You see on this Island are from military firing exercises. To the west is Camp Lejune. They Fire live rounds all over the place and Browns Island is often a Target. They will even Close Down the intracoastal waterway during these live fire exercises. They are not tidal fish traps, or anything ancient in origin they are simple craters from live fire.

Re: SD What is it? Lake Okeechobee- Part 2
|
|
You are right. There is an object in the lake causing a disturbance in the water. It was known to ancient man as a boat. The bright line is known as prop wash and the waves reflecting off to each side are known as wake. Often brackish water will foam up, leaving a long lasting trail of bubbles from the propwash.

the lines appear to be county boundaries. do you mean the straight blue-green lines?

|
Re: What is it?Lake Okeechobee Linear feature
|
|
Not positive if this is what I think, but when Okeechobee was setteled in the late 1800's the original flood control was a series of deep canals dug around the lake. when the lake would rise the canals would divert water away from the town. I think that's what your looking at here. It would be underwater now because of the construction of the Hoover dike around the lake.

I believe that is cap rock., fought a few fires in that area and the stuff makes for some hard work, some kind of moss or something like it grows on the rock, that would be the dark area's your seeing.

SD Cuba Circular and Patterned Anomalies
|
|
A lost city has been reported and documented off the Northern Coast of Pinar del Rio by Charles Berlitz. The placemarks in the following image studies reveal areas with patterning, circular features and more linear features just like those seen in the Bahamas near Proctor's Road and the Bimini Wall. Most of the features including the linear features are found underwater North of Pinar del Rio.
'An expanse of stone ruins, several acres in area and apparently white, as if they were marble, was reported off the northern coast of Cuba by the late Leicester Hemingway former resident of Cuba and brother of the famous novelest...' referring to Ernest Hemingway. This was documented in a book by Charles Berlitz.

The brown areas are water that is tinted brown by the tanic acid drawn out of the dead mangrove leaves. The green are the red mangroves. I have not been exactly there, but it is similar to other places in the glades I have been. Very mucky, from years of deterious material build up. Proably a foot or less of water. I doubt if there is any actaul ground their above sea level. Very sure that was never a site used by the indigeous tribes. Several of your other post show natural features also.

Re: SD What is it? Syria, Rectilinear Features

What a great thread!
It was fun to look at each item and then think about it and then read the replies. I saw good explanations for most everything except the patterns in Iraq. It almost looks like a city layout but I doubt that's what it is.
If you go into Syria a bit from there, there are a lot of other great things to ponder. The big black spot, the "walled" square, which really looks more like the "ditched" square. And all the crazy pattern tire tracks.
So all you smart A%#es that were so clever on the easy ones. What is the stuff in the Iraq post?

These are prop wash marks that scar the bottom growth, from a power boat at low tide or boat with deep draft.

Parallel features off the coast of NC. A distinct edge can be seen of what looks like a submerged, Carolina bay. The area within this 'bay feature' contains parallel features that seem to be equidistance apart.
-Actually, this is a very common sight near an active inlet. The discoloration you see is called a "plume" and is actually being created by water exiting the Carolina Beach Inlet on the falling tide. Scroll a little farther south to the mouth of the Cape Fear River and you'll notice the same thing happening there.
