@farmerman,
farmerman,
Thanks for the link. Couldn't get it to work. You must mean PDF: "Neotectonics of The Northern Mississippi Embayment" by John Nelson and Richard Harrison? Thanks, I have read their work.
It is my belief that the topography of the embayment is due to a bolide impact to Northeastern Marshall County, Mississippi. Here is a brief description of how I view the valley:
On satellite, put the upper embayment in view. Draw an imaginary line down the middle of The New Madrid Bend straight to where numerous unusual rocks were found in North Slayden, Mississippi [Concord Church is near the middle of the crater?]. Notice the lines in the topography showing angle, force and direction of impact. Follow each river to the north [Wolf, Hatchie, Loosahatchie,...] down each of their valleys to view the larger waves from a shock that extends from The Tennessee River on the east around passed The St. Francis River on the west. All the semi-circular fractures and "sand blows" point directly to this structure. The man-made lakes to the south [Sardis, Enid, Arkabutla,...] is where the land was split apart and pulled upward by the force. Later these chasms were blocked by earthen dams to form lakes. Every river, lake, hill, valley, and every detail in the topography surrounds and points directly to this same central location.
On the northwest face of this structure is where numerous unusual rocks were found with the appearance of melt rock, fusion crust, vitrification, shatter cones, fallback breccia, shocked quartz, nanodiamonds, etc. All aspects of impactites.
William Herschel's observations concur. The comet was seen as fifty percent larger than the Sun in October 1811. Many reports of major meteor showers, black smoke, explosions, hot and cold blasts of air, lights across the skies from way too far to be naturally occurring earthquake lights. It would have taken this amount of force, a meteor impact, to cause the churchbells to ring in Boston and throughout the northeast [no, not a myth]. All these reports were only during the first major quake.
It is my belief that C/1811 F1 came up from the southern hemisphere [where it was last seen before passing] and passed in front of our planet, leaving a trail of debris. As Earth travelled through its dust tail [for over a month] several meteors impacted. One large enough to cause this destruction. Please read Alexander von Humboldt's account:
http://ebooks.adelaide.edu.au/h/humboldt/alexander/travels/chapter14.html .There was a major earthquake in Caracas Venezuela in December 1811 as well as many eruptions, quakes, strange weather patterns,...all over the globe. It is my belief these were the effects of a comet's close passing.
Please study the satellite view, study the rocks, the original accounts, newspaper articles, present theories, tree growth data, immediate topography,... I have little doubt that once all the evidence has been studied that this will be the only conclusion. A meteor impact is the only mechanism that could have possibly produced the highly unusual topography of The Mississippi Embayment.
What do you think?
