These artifacts are an entirely different issue then the alleged "roads" because nobody has presented any proof that the barrels and columns are connected in any way to what people claim to be roadways. Thus, they are discussed in a post that is in preparation. The Pleistocene limestones on which the barrels and columns lie range in age from 15,000 to 23,000 B.P. (Gifford 1973). Because wave action from storms and currents periodically mix the deposits that lie on the Pleistocene limestones, the shells and artifacts that lie upon can be of any age that postdate it. In examples documented by Flessa (1993), the mixing of nearshore surficial deposits by storms has produced deposits containing shells that range in age from modern to greater than 36,000 B.P. as dated by radiocarbon method. A similar mixing of old and new shells and artifacts has likely occurred within the Bimini nearshore deposits given the periodic hurricanes that have hit the region.

I don't know if this is Atlantis and don't These are untrue statements indicative of sloppy scholarship. Carbonate sedimentologists and other geologists have traveled to the Bimini Islands to study the large slabs of limestone that people claim are ancient "roads". They have produced detailed studies of the Bimini area. Specific studies are Ball and Gifford (1980), Gifford (1973), Harrison (1971), Shinn 1978), and McKusick, and Shinn (1978). Other important Bimini studies are Davaud and Strasser (1984), Strasser and Davaud (1986), and Supko and others (1970). References cited; 1.

I have spent hours and days with them Just being a diver does not give a person the ability to understand the complex processes that create beachrock and other carbonate rocks. Some knowledge of and experience in studying carbonate rocks (limestones and dolomites) is needed to interpret what is going on. As I will go into detail below, expert carbonate geologists, Gifford (1973), Ball and Gifford (1980), Sinn (1978), and McKusick and Shinn (1980) have examined the slabs of limestone and found overwhelming evidence that the so-called "Bimini Roads are nothing more than rectangular slabs of beachrock. .....material omitted In article , (Re: Atlantis-any proof ?) firstname.lastname@example.org says; >email@example.com (Eugene Powell) wrote: >>I believe a slight correction or amendment to this comment might >>be that the so-called Bimini road APPEARS to be similar to natural >>formations that do mimic the rectangular blocks and joints, but I do >>not think the Nature article PROOVED the Bimini road is a natural >>formation.

For the study of these blocks, they completely surveyed the three linear strips of slabs that comprise the "Bimini Roads"; completed photomosaics of the features composed of a linear concentration of slabs; described the orientation and physical characteristics of slabs; surveyed in the position of the strips of slabs in relation to benchmarks on North Bimini; obtained core samples from individual slabs within the "Bimini Roads"; prepared petrographic thin sections from the cores and other samples from individual slabs; and dated samples from the slabs by radiocarbon and uranium-thorium methods. They observed that these linear features lay roughly parallel to the modern shore and no discernible destination at their ends. Field Investigations The observations made by Ball and Gifford (1980) are; "1. The three features are unconnected at the southwest end; scattered blocks are present there but do not form a well-defined linear feature connecting the seaward, middle, and shoreward features. 2. No evidence exists anywhere over the three features of two courses of blocks, or even a single block set squarely atop another. 3. Not enough blocks lie in the vicinity of the three features to have formed a now-destroyed second course of blocks. 4. Bedrock closely underlies the entire area of the three features eliminating the possibility of excavations or channels between them. 5. Indications are that the blocks of the inner and middle features have always rested on a layer of loose sand. No evidence was found of the blocks being cut into or founded on the underlying bedrock surface. 6. In areas of the seaward feature where blocks rest directly on the bedrock surface, no evidence was found of regular or symmetrical supports beneath any of the blocks. 7. We saw no evidence on any of the blocks of regular or repeated patterns of grooves or depressions that might be interpreted as tool marks. 8. The inner and middle features are continuous only over a distance of about 50 meters. Though the seaward feature extends several hundred meters farther to the northeast, it too is not well founded or continuous enough to have served as some kind of thoroughfare. In fact, the only attributes of the three linear features that suggest a human origin are the regular shapes of some of the blocks. These are also attributes of natural beachrock deposits." Laboratory Analysis Their laboratory analysis found overwhelming evidence that the slabs that composed the three linear features studied above consist of natural beachrock of local origin. First, the shells and other grains that compose the slabs are identical to the grains in the loose sediment underlying the slabs. Second, the carbonate cements are typical of cements found in modern beachrock. Third, oxygen and carbon isotope composition of the cements that form the beachrock are consistent with the composition of modern beachrock cements. Finally, the radiocarbon dates obtained from the slabs of beachrock ranged in age from about 2300 to 3200 B.P. for the shoreward line of beachrock and a single date of about 6800 B.P. for the seaward line of beachrock (Gifford 1973; Ball and Gifford 1980). McKusick and Shinn (1980) obtained some oriented cores from one of the linear features. X-radiographs of 17 oriented cores showed that the slope, particle size, dip direction, of the bedding is consistent from one block to another within two areas studied. If the blocks had been quarried from one place and laid out as a road, the original stratigraphy of the beachrock would not have been preserved. Clearly, these slabs represent beachrock that developed in situ along three shorelines. They also dated 7 samples from the slabs and obtained dates ranging from about 2750 to 3500 B.P. (Shinn 1978; McKusick and Shinn 1980). Results The results of the studies by Gifford (1973), Ball and Gifford (1980), McKusick and Shinn (1980) clearly demonstrated that so-called "Bimini Roads" are not man-made features. Rather, they represent beachrock that formed along the shore of North Bimini Island at three different shoreline during the Holocene when sea level was lower than present. Also, the photomosaics demonstrate that the lines of slabs are not well founded or continuous enough to have served as any kind of road. >There are clearly shown dressed stone columns in 30 feet of water. > I can't remember the magazine, but somewhere I saw an article on >a piece of carved sculpture that was brought up from this site.

At this time, you have failed to post any evidence that shows that your "feline form" is in any way related to the limestone slabs which you claim to be the "Bimini Road". Therefore, it is discussed in a separate post with the "stone columns." >Whether or not this is a fragment of something called Atlantis, >those stone "formations" are OBVIOUSLY artificial, even with >ages of ocean slime on them. They are not natural, as anyone The only characteristic of these stone slabs suggestive of human manufacture is their rectangular shape. If a person take the time and trouble to study the available literature, that person would find that there are several places where rectangular slabs of beachrock are associated with carbonate beaches. In fact, rectangular-jointed beachrock that time will become rectangular slabs of beachrock occurs on the west shore of South Bimini Island. Places where observed (reference) 1. Puerto Rica (Kye 1959) 2. Barbados (McLean 1964) 3. west shore of South Bimini (Ball and Gifford 1980) 4. Joulter Cays, Bahamas (Strasser and Davaud 1986:Figure 6a) 5. Heron Island, Australia (McKusick and Shinn (1980). 6. eastern Australia (Randi 1981). Given the numerous locations at which the formation of rectangular blocks is occurring, the rectangular shape of the slabs of beach rock found off of Bimini Island cannot be used as evidence for their human manufacture. Therefore, there is a complete lack of evidence for any human modification of these slabs. References cited; Ball and Gifford (1980) - see above for citations.

All this knee-jerk "there Ball and Gifford (1980) and Gifford (1973) had the "gumption" to out and look at these beachrock slabs in person. As previously noted, they were extremely unimpressed with the hypothesis that they were artificially made. As describe above they, found overwhelming evidence that these were indeed natural slabs of beachrock lacking any human modification. >was no Atlantis" is pure parrot party line.

This is all malarkey and hot air. There are numerous archaeologists that would sell their grandmother for evidence that Atlantis actually existed and lust for the publications and grant money that such a discovery would bring. Archaeologists are all too aware of what they do not know. However, theories and speculation is cheap, it is being able to prove a theory that makes a true scientist. Back to article , in which firstname.lastname@example.org says; >Something artificial is sitting on the ocean floor off Bimini, >very much like old Port O Prince came to be in historical times, >and the pedagogs have not a single word to account for it >--except DENIAL. I my opinion, the real people who are in denial are the people who keep insisting that what they call the _Bimini Roads_ are actual artificial structures. As above publications document, there is an absolute lack of any evidence that they are roads or any other man-made structures. However, if people want to waste their lives chasing a ghost, it is not my problem. However, they should not be claiming that features are man-made structure without presenting some evidence that they are artificial structures. Also, they have to refute the work done by Ball (1980), Gifford (1973), and McKusick and Shinn (1980) that provide direct evidence that these "roads" are something more than natural beds of beachrock for specific reasons. Simply dismissing this research as the work of bigoted and biased archaeologists is insufficient reason to dismiss to hard work and detailed research that clearly proves that the so-called Bimini Roads are nothing more than Holocene beachrock formations.
