600 Mile Wide Impact Crater in the Pacific NW caused the Younger-Dryas extinction level event.

Nothing in this paper argues ‘for’ or ‘against’ theology-creationism, or ‘for’ or ‘against’ gradualism-evolution. My sole interest is finding facts without regard to whether they support one side or the other of the argument. My opinion is they both are about equally in error.

There is an impact crater in the Pacific Northwest (Sacajawea impact crater) and a larger "exit wound" crater on the opposite side of the globe (the Taklimakan Desert in Western China), the primary impact point is near Sacajawea Peak in North Eastern Oregon. It is a complex crater with a clearly visible crater rim, and can be seen by a casual observer at about 600 mile altitude on Google Earth. An Eastern slope failure is the Yellowstone Basin. Northern ejecta is visible as the Rocky Mountains and the Canadian Range into Alaska on the NW side, and into Utah, Nevada and California on the South side. 



On the western edge of the crater are the "NW Ring" of volcanoes, which consists of Mt. Sister, Mt. Jefferson and Mt. Hood in Oregon; as well as Mt St. Helens, Mt. Adams and Mt. Rainier in Washington State.

The gigantic size of this crater at more than 600 miles wide covers 80% of the state of Washington, 100% of the state of Idaho, and about 75% of the state of Oregon, which suggests that the impactor was something in access of 25-30 miles wide.

Based on the oblong scar opposite the Sacajawea impact crater, in the Taklimakan Desert in Western China, the exit scar appears larger than the impact crater at about 800 miles in width. It certainly appears to be an exit wound with errata and ejecta into Afghanistan, Pakistan and Iran. It has an obvious visual appearance of an "exit wound" with several smaller 'exit wounds' in its general vicinity. If a large meteor struck the earth that was over 25 miles in diameter, could it penetrate the crust and Earth's upper mantle, travel through the liquid molten center, and exit through the upper mantle and crust on the opposite side of the globe?




Simple ballistics will give us a good idea. If we reduce the Earth down to the size of a large goose egg, (about 10" in circumference around its longer side) the Earth' crust and upper mantle would be roughly the thickness of the goose egg's shell and inner membrane. The inter mantle, magma and core of the Earth would be roughly equivalent to the goose egg's inner white and yolk sack, although the goose egg interior mass is probably less dense, when compared to the Earth's core. But generally speaking they are roughly equivalent. For the experiment I would recommend draining the egg though a small hole, and filling it with a gel like substance to mimic the Earth's core density.

The Earth is just less than 8,000 miles in diameter (actually 7,918 miles) at the equator. But more importantly, the surface (circumference) of the Earth at the Equator is just less than 25,000 miles. (Actually 24,901) Divided by 30 miles, (the size of the 'asteroid') readily shows us the the projectile would be 1/830th the size of the Earth.

Reducing 1/830th of the Earth's surface to the size of a large goose egg (measuring around the egg the long way) which is, on average about 10" more or less, when converted to millimeters, 10" equals 254 millimeters. Dividing the 254 millimeters by 830, returns a projectile roughly 0.30 millimeters in diameter. (Or about 1/64th of an inch) Or, about the size of the period at the end of this sentence.

Now, if we look at the speed of the 30 mile asteroid, which generally enters the atmosphere at (give or take) 25 miles per second, (or about 132,000 fps), and impacting the Earth at something less than that, less than 90,000 fps). Which takes into consideration the very slight braking effect of our atmosphere. (traveling at 25 miles per second means the asteroid would be in our atmosphere for about 7-8 seconds.

Reducing the 'asteroid' projectile to the 'sentence period' as defined above (as it relates to the goose egg), means the period sized projectile would travel about 1,084 fps on impact and travel on through the egg. Depending on internal deflection, it would exit the egg roughly on its trajectory, without much surface damage to the egg shell. If equivalent to the Earth, the entry hole on the eggshell would have roughly a 5 mm entry wound. The exit wound would be a 'blow out' crater, significantly larger than the impact crater, which is exactly what the Taklimakan Crater in China shows. If the impact spherule were larger, it would damage the entire egg structure, but its small size in comparison to the egg shell suggests it would penetrate the shell, travel through the egg center and exit out the other side.

The above is quite easy to test in a laboratory setting. If the ballistic dynamics are as close to what is related here, it would demonstrate that a 30 mile diameter object could and did penetrate the Earth's crust sometime in the past, leaving the residue of the Sacajawea Crater and the Taklimakan Crater as its calling card.

This is different information than has been presented before, so it puts in question the long held macro time scales for large impact craters of a lot smaller size. There are several good solution to this problem. One might be to do 14c tests on Clam beds in the high Plateau of the Colorado Rockies. Another is to definitively c14 test the Yellowstone Gorge. That geological anomaly is currently dated to between 10,000 and 14,000 years in age based on preliminary c14 tests.



The Sacajawea Crater, based on the c14 dates of the Yellowstone Gorge, fits the model as the driver of the mega-extinction of giant flora and fauna at the Younger Dryas evemt at about 12,800 years ago. It is not my purpose to argue the Y-D barrier, only to postulate the Sacajawea impact as the primary driver for the ensuing mega extinction. It also fits most other anomalies in the geological record surrounding the Y-D event. For example, the deliberate burial of Gobelki Tepi, and the megalithic cultures of the high Andes, Egypt and the Near East.

It is not the object of this report to speculate on the ensuing global cataclysm following the impact. It is, however, quite evident that the catastrophe that followed would have been more devastating than the Chicxulub impact event that ‘supposedly’ killed the dinosaurs, as argued to have happened 65 million years ago.

I will make the declarative statement that the Sacajawea impact event at 12,800 ybp DID in fact drive many giant flora and fauna INCLUDING some surviving species of dinosaurs into near extinction, with a few remaining scattered groups surviving into the late Holocene (near modern times), providing models for rock drawings, clay models, tapestry and figurines, etc. The Younger-Dryas event is recognized to be centered in North America, which also fits the model. In a later Blog, I will make the case for Dinosaurs living up into the late Holocene, but the primary proof is the more than 63 DNA tests done on un-fossilized dinosaur bones returning dates of 12,000 to 42,000 ybp. (In addition to Dr. Mary Schweitzer (of North Carolina State) who found “elastic collagen and hemoglobin elements” in a T-Rex hind limb. (that is “Blood and Tissue” for you non techies.) 13K years is the extreme outer limits for survival of unstable biological elements. Certainly NOT 65 million years. If you don’t believe me, ask any biologist or chemist.

Your review and counter argument is appreciated.

  1. Has the Sacajawea Crater in Oregon been identified by geologists using impact crater studies that include such things as shock metamorphosis, shock melt, petrology, remote imaging, or other similar means?

  2. From chapter 10 of my book "Earth Epochs" free here:

    Black Mat - Excerpts from a News Release by UC Santa Barbara:

    In Central Mexico, Scientists have identified a thin, dark layer of “exotic” sediment materials in the floor of Lake Cuitzeo consisting of Nano diamonds, impact spherules and more, which are the result of a serious Earth impact caused by a cosmic body.

    This new data provided by James Kennett, Professor of Earth Sciences as UC, Santa Barbara and his 16 member international team is the latest to strongly support the controversial hypothesis that the Earth experienced a major cosmic impact 12,900 years ago. The researchers identified a family of Nano diamonds, including lonsdaleite, which is unique to cosmic impact by conducting a wide range of tests.
    The team also found evidence of high velocity impact spherules that had collided with other spherules during the impact chaos. Kennett noted that such features could not have formed through volcanic, anthropogenic, or other natural processes. “These materials form only through cosmic impact,” he stated.
    Based on the data and evidence which points to an extremely large asteroid or comet entering the atmosphere at a rather shallow angle with a very high heat index at impact. Surface heat increased to a level that melted surface rock and burned large quantities of biomass. The result caused major disruptions of the environment on a wide scale basis.

    Kennett explained:
    “These results are consistent with earlier reported discoveries throughout North America of abrupt ecosystem change, megafauna extinction and human cultural change and population reduction.”
    Age of the sediment layers, according to the research team is the same age as that reported at other locations in North America, Greenland and Western Europe, or about 13,000 years old. In the complete geologic column there are only two known continent wide layers with high peaks of Nano diamonds, impact spherule, and aciniform soot. These are the Cretaceous-Paleogene boundary (and extinction level event) and the Younger-Dryas boundary event at 12,900 years ago that is closely associated with the extinction of many large North American animals, including saber tooth cats, dire wolves, mammoths and mastodons.

    Kennett said "The timing of the impact event coincided with the most extraordinary biotic and environmental changes over Mexico and Central America during the last approximately 20,000 years, as recorded by others in several regional lake deposits. These changes were large, abrupt, and unprecedented, and had been recorded and identified by earlier investigators as a ‘time of crisis.' ".

    Other scientists contributing to the research include Isabel Israde-Alcántara and Gabriela Dominguez-Vásquez of the Universidad Michoacana de San Nicólas de Hidalgo; James L. Bischoff of the U.S. Geological Survey; Hong-Chun Li of National Taiwan University; Paul S. DeCarli of SRI International; Ted E. Bunch and James H. Wittke of Northern Arizona University; James C. Weaver of Harvard University; Richard B. Firestone of Lawrence Berkeley National Laboratory; Allen West of GeoScience Consulting; Chris Mercer of the National Institute for Materials Science; Sujing Zie and Eric K. Richman of the University of Oregon, Eugene; and Charles R. Kinzie and Wendy S. Wolbach of DePaul University.

    It is more likely, rather than less likely that a major impact event occurred in the Pacific Northwest circa 12,900 YBP. As the Sacajawea crater bowl appears to be the only extant crater rim in the area, it is also likely that it is the impact point in question.

  3. Wow, I have been studying the Taklimakan Desert as a crater for a while and am so glad someone else on this planet suspects this to be a crater! I have never thought of it as an exit crater and this info will give me some food for the thought! Whatever happened definitely convoluted the areas to the west, created the Tibetin Plain and could have been responsible for the extreme upheaval of the mountain range to the south (Mt Everest etc). I would suspect that molten material flowed to the southeast down into Laos. I will also bet that there is a lot of gold down in the original flow. That what is looks like. Something huge happen there!
