Landsat Data Used in Chevron Discovery

The chevrons are found within the red circles on this Landsat 7 image.
Recently a landform called a chevron was noted on a Landsat 7 image of Madagascar. These chevrons may have been formed by a mega-tsunami produced 4,800 years ago by a meteorite or comet impact with the Indian Ocean. I have included a close up Google Earth photo of the chevron on the left in the Landsat photo. You can type in the coordinates in Google Earth and go there yourself and investigate.
Discover Magazine (2007)article on this topic … “Did a Comet Cause the Great Flood?”
New York Times (2006) article on this topic … “Ancient Crash, Epic Waves”
This is very interesting to me because I have noted for some time how the work of Henry Morris and other neo-catastrophists has had the effect of pushing mainstream geologists ever closer to reconsidering the Global Flood as a starting point for all inquiries in historical geology.
It is also interesting because of my interest in Dr. Walter Brown’s Hydroplate Theory which postulates a catastrophic bursting open of the Fountains of the Deep. Brown says that comets and asteroids were launched during this time. Did some of them “return home” shortly after or during the Flood?
It is also interesting that Sir Charles Piazzi Smyth, one time Astronomer Royal for Scotland dated the Flood at 2743 BC based on data from the Great Pyramid of Gizeh and upon ancient literature surveys. This is very close to Bruce Masse’s date for this postulated comet/meteor impact of May 10, 2807 B.C. (See Discover Mag article above) Piazzi Smyth made very detailed measurements of the Great Pyramid and concluded that it was built by people with highly advanced scientific knowledge. The great Egyptologist Sir Matthew Flinders Petrie was fascinated with Smyth’s work and made his own investigation. He concluded that one of Smyth’s key measurements was wrong, but Smyth was later vindicated and shown to be in agreement with Petrie’s measurements. See my discussion of this topic with Dean Anderson, a former administrator at IIDB HERE.
And finally, a recent Science (2005) article on … “Tracking Myth to Geological Reality” which notes that …
More and more geoscientists are willing to combine their work with such stories these days, in a budding discipline called geomythology. Volcanologist Floyd McCoy of the University of Hawaii, Manoa, says discussing myth has traditionally been “a good way to sink your own credibility”; it can put you on the list with flaky Atlantologists and other amateur zealots. But, says McCoy, “I’d be a fool to write it all off. There is a new realization that some myths have something to say.” Myths can sometimes alert researchers to previously unheeded geohazards; in other cases, where science has demonstrated the danger, legends “enrich the record” and reinforce the fact that people lie in harm’s way, says paleoseismologist Brian Atwater of the U.S. Geological Survey (USGS) in Seattle, who has spearheaded many studies of seismic events in the Pacific Northwest. The trick is teasing out which myths carry kernels of truth that can be connected to hard data.Deities of flood and fire
The movement traces in part to the 1980s, when scientists realized that the slow march of geologic time is sometimes punctuated by biblical-scale catastrophes, such as the giant meteorite that wiped out dinosaurs 65 million years ago. After this was accepted, some (usually those with tenure) felt freer to wonder if near-universal myths of great floods and fires implied that such disasters also have punctuated human time. In the 1990s, Columbia University marine geologists Walter Pitman and William Ryan argued that rising Mediterranean sea levels following the last deglaciation topped what is now the Bosporus Strait and roared into the Black Sea 7600 years ago, serving as the original inspiration for the biblical flood. Their work triggered sharp criticism and a torrent of research, resulting in growing acceptance of some sort of Black Sea flooding (Science, 22 September 2000, p. 2021). Whether the book of Genesis somehow grew from this is a further step, admits Ryan, who presented his latest findings at the International Geoscience Program in Istanbul, Turkey, in early October.
