impact The Chesapeake Bay impact crater was formed by a bolide that impacted the eastern shore of North America about 35.5 ± 0.3 million years ago, in the late Eocene epoch. So, basically 100% of the excavated ejecta would never come back, having exceeded the escape velocity of the asteroid. endstream

16 Psyche is over 200 km i diameter, which is the main reason for its high escape velocity. The great pressure from hyperspeed impacts creates planar deformation features in quartz crystals that distinguish impact craters from craters formed by terrestrial processes. Yes, Chesapeake Bay is part of an impact crater, with the crater itself centered on the southern end of the Delmarva Peninsula. But gaze below at the monstrous concentric gravity rings surrounding Saginaw Bay…, From: “The putative Saginaw impact structure, Michigan, Lake Huron in the light of gravity aspects derived from recent EIGEN 6C4 gravity field model“, Journal of Great Lakes Research, December, 2018. Psyche’s full designation is 16 Psyche. The U.S. space agency reports in a news release that this is now one of the 25 largest impact craters on our planet, and that it measures about 1,000-feet deep and with a diameter of 19-plus miles. A quick look will point out one reason Psyche is notable. And all that material is GONE. %%EOF
Psyche speaks pretty loudly for my side of this argument. Sixty-one bottom samples were collected on a semigrid pattern and analyzed physically. It is a shallow-water derivative of the Pleistocene Lake Saginaw. ). That depends on the escape velocity. Here, we used the recent gravity field model EIGEN 6C4 and a set of gravity aspects (sensitive in various ways to the underground density contrasts), derived from its spherical harmonic coefficients (Stokes parameters) to degree and order 2190, with a ground resolution of ~9 km. This is the wind, wave and weather forecast for Saginaw Bay Light in Michigan, United States. No aggregation going in here, boss! The low-angle impact upon the icesheet kicked out mountain-sized slush balls into the atmosphere and the Carolina Bays are the resulting splatter. It would fly off into space and keep going. May 27, 2020 - Saginaw Impact Manifold Overview - Figure 10 - Carolina bay locations distributed in butterfly arcs symmetrically around Saginaw Crater (Ice Sheet above blue line) I bring it up because those deep craters illustrate something I argued in the past here. Very, very hard to go to GSA conference after GSA conference, year after year, postering a nutty hypothesis not one single person in the huge hall will even entertain. Help, oh people of the rocks. Saginaw Bay in Great Lakes Bay, Michigan is perhaps the worlds best walleye fishery. "! It is a shallow-water derivative of the Pleistocene Lake Saginaw. 4���o1���-����;��ft�y���m2��e�⃨b�b+A�,�.A�.���Q�/ �m�
Windfinder specializes in wind, waves, tides and weather reports & forecasts for wind related sports like kitesurfing, windsurfing, surfing, sailing, fishing or paragliding. For the Saginaw Bay area, we confirm that we do not see any typical impact crater in terms of gravity disturbance or the radial second order derivative, possibly because of the thick layer of the ice located at the place and time of the impact. The hypothetical impact structure in the Saginaw Bay (Michigan, USA, Lake Huron) has been tested by the gravity data derived from the recent gravity field model EIGEN 6C4 (expanded to degree and order 2190, with ground resolution of ~9 km). Along the Hudson Bay arc, bodies of pseudotachylite, monomict and exotic breccias are associated with faults, and overlying sediments may show evidence of re-worked impact melts. Ejecta velocities range about 0.4 to 0.55 of the impact velocity, so anything impacting above 10 kps (relative velocity) would have an ejecta velocity of about 0.47 kps. The important question of how large the impactor was that formed the crater remains unanswered. The smaller one obliterates a region of the larger one. For example, Barringer Crater, Arizona is 4000 feet wide and 570 feet deep. From Quanicassee to Fish Point most anglers were shore fishing because of the wind and rain. Discover (and save!) The cascade of stupefying new discoveries continues. That is what we see in all craters – the target material failed. Besides its shallowness, there is no impact ejecta. But if this is true, then the Carolina Bay impacts must be coincident with a mass extinction of fauna, especially in North America, and also coincident with a major change in the climate of the northern hemisphere. Een inslagkrater (of inslagbekken) is een krater (een komvormige of ringvormige landschapsvorm) die in de bodem van een hemellichaam achterblijft na de inslag van een ander hemellichaam.. Het inslaande lichaam is meestal een meteoriet, die van een komeet of een planetoïde afkomstig kan zijn. Findings were treated statistically. The Chesapeake Bay impact structure, Virginia, is the largest impact crater in the United States. Lake Huron's Saginaw Bay is known as the Walleye Capital of the World. The American Meteor Society took many of the reports of sightings and derived a path of the meteor.. R%R@-u"��ɐU9/m�4�a�xlC��A� �JG;R"�Qd%1���9��N�ε2X��xh�Y�]����S!Q��ҝ�" We have followed the chronological constraints to a proposed date of ~787 ±5 thousand years ago. Considered to be one of the best-preserved “wet-target” impact craters in the world, the Chesapeake Bay Crater is the largest known impact site in the United States. Bullets do what they do – obliterate target materials – because of the energy the bullet has at the speed it is going, and the limitations of a thing called unit stress, as it applies to yield stength. Gonna be a big Christmas over at the Davias household! The hypothetical impact crater in the Saginaw Bay (the Great Lakes area), has been studied from various views. Alphabetical lists for different continents can be found under Craters by continent below. Short answer: When a meteor hits the lunar surface, a shockwave spreads out in all directions and the impact creates a dent in the surface that is much bigger than the size of the impacting object itself. A NASA glaciologist has discovered a possible second impact crater buried under more than a mile of ice in northwest Greenland. It is one of the best-preserved "wet-target" impact craters in the world. Continued slumping of sediments over the rubble of the crater has helped shape the Chesapeake Bay An example martian oblique impact crater with a butterfly-shaped ejecta blanket overlain on a Google image of Saginaw Bay GIF images courtesy of Michael E. Davias—‘Correlating the Orientation of Carolina bays to a Cosmic Impact’ mouseover the time machine set to 785 t.y. They don’t. That is about 40 times as big as Barringer Crater. Saginaw Bay is a southwest extension of Lake Huron on the east shore of the Southern Peninsula of Michigan. When the asteroid struck the Earth, it is said to have caused a dizzying wave of water that reached 1,500 feet in height. 95% of the volume of the craters is GONE. I ran across a news article that said NASA was quite interested in the asteroid named Psyche. Saginaw Bay fingered by gravity data as ice impact feature, Davias and Harris at Cintos.org vindicated, Astronomical Hypothesis for the YDB Impact Event, The Carolina Bays: George Howard’s Original 1997 Web Essay, The Younger Dryas Impact research since 2007, Tusk and UnchartedX join The Randall Carlson Podcast, Cycle of Cosmic Catastrophes pinned on fragmenting Taurid comet, Read the papers: Covid is probably from Space, Tusk returns from epic Ancient Egypt Technology tour, Sweatman destroys Sun et al. While the sensor does not capture enough detail to see the piles of ice on shore, the Moderate Resolution Imaging Spectroradiometer ( MODIS ) on NASA’s Terra satellite observed the impact of the storm on the ice in the bay … But as of 2015, 128 terrestrial impact craters have been identified on Earth. �lC�Y"� At the time this area was covered with a mile or two of glacial ice. The Saginaw Bay Impact page: 1. Correlating the Orientation of Carolina bays to a Cosmic Impact Sediments range in size from large pebbles to clay. So, I believe that Psyche’s meetings with other bodies were essentially two bullets in flight hitting each other at random. Archived. in rapid review. Windfinder specializes in wind, waves, tides and weather reports & forecasts for wind related sports like kitesurfing, windsurfing, surfing, sailing, fishing or paragliding. If investigations are positive, Hudson Bay arc would form part of the largest identified multi-ringed impact on Earth, with a minimum diameter of 450 kilometres. ���/X�7i1N�6�`�,��q�A�?��|�O�|M/���z��Twf��̔�xCv�L�@ Close. I found it in what is the Lake Erie and/or Saginaw Bay impact crater area. Overview. But to derive this Great Lakes orientation, you need to allow for coriolis ‘force’ (reaction) and impact-drift. But the “combed” strike angles (one type Look at the other contraindications. Carolina Bay characteristics This section examines various physical characteristics of the Carolina Bays to try to determine mechanisms by which their features could have originated. Posted by 6 years ago. Saginaw Bay is a bay within Lake Huron located on the eastern side of the U.S. state of Michigan.It forms the space between Michigan's Thumb region and the rest of the Lower Peninsula of Michigan.Saginaw Bay is 1,143 square miles (2,960 km 2) in area. Because the final crater may be as much as 100 times greater than the diameter of the impactor, this requires an impact at an angle of no more than a few degrees from horizontal.

For the Saginaw Bay area, we confirm that we do not see any typical impact crater in terms of gravity disturbance or the radial second order derivative, possibly because of the thick layer of the ice located at the place and time of the impact. Analysis of deformed rock and gneiss breccia encountered in a drill hole one mile from shore suggests that the original crater diameter is about 31,000 feet, considerably less that first estimated (Innes 1964). Die Saginaw Bay (Saginaw-Bucht) ist eine Bucht des Huronsees, die an die Countys Arenac County, Bay County, Tuscola County und Huron County im US-Bundesstaat Michigan grenzt. Based on the convergence point of the Carolina Bays and Nebraska Rainwater Basins, the impact point is Saginaw Bay and the crater may be Huron Lake whose deepest point is perfectly aligned with Saginaw Bay. I argue that the planetary nebula theory is flawed because any impacts at the velocities of asteroids and comets and planets are going to REMOVE material from the two bodies involved, if not destroy one of them altogether and leave a huge crater in the other. Psyche seems to illustrate that, in spades. There has been a lot of talk about the Carolina Bays and what caused them, recently two reaserchers, Micheal Davias and Thomas Harris, have proposed a new scenario on how the bays were formed, and how they are connected to the Australasian Tektite strewnfield. A paper published today in the Journal of Great Lakes Research provides evidence from gravity anomalies that Saginaw Bay in Michigan is a remnant feature of an impact into an ancient ice sheet. They have done one hell of a lot of work on the subject, admittedly not in the field or the lab, but — from one pajama scientist to another — they deserve immense credit for intellectual bravery. Some of the world’s largest impact craters are in Canada. h�b```f``e`e`~� Ā B@16�ǒZ4&������ˬo���;[�B�����^z$YD��T�������ThS��vX�� _���737�p�H�cb�I��T�MSQ�mN��Lc���\�AJ�BV�$�����l���+���.WY:فRm The impact crater may have been between 32 and 114 kilometres in diameter (compare to the 180-km Chicxulub crater). Both of these impact craters are now filled with water. Saginaw Bay is a southwest extension of Lake Huron on the east shore of the Southern Peninsula of Michigan. The ejecta? It is evident that finding a crater at this point, taking into account that the planetary body that produced it impacted on a mantle of ice more than 1Km thick (between 1 and 2 Km thick) is very difficult. This list of impact craters on Earth contains a selection of the 190 confirmed craters given in the Earth Impact Database.. To keep the lists manageable, only the largest craters within a time period are included. �O��{!/�2 ��8�F`��� ���i�K�r`&Ǘ!���À The goal of this reef restoration project is not simply to create additional spawning habitat, but rather to facilitate a resilient and diverse fish population. Discover (and save!) Also, some recent estimates suggest that the strewn field may cover 30% of the Earth's surface (Povenmire et al. share: punkinworks10 +3 more posted on Jul, 28 2015 @ 09:40 AM link . The cascade of stupefying new discoveries continues. And what about the debris? On the southeast corner of Hudson Bay, the coast line traces a near perfect arc, roughly concentric on another ring of islands in the bay. Jun 1, 2014 - Saginaw Crater. Analyzed data now shows where the meteor could have hit ground in Michigan. The proposed cratering impact, when combined with the scouring action of 7 full glacial ages, is seen producing the current-day Saginaw Bay Basin.

A back of the envelope measurement on the screen tells me that the big crater is about 50-75 kms in diameter. If you are interested in the Younger Dryas Impact Hypothesis, and not been hiding under a YD impact launched rock for the last decade, you have probably encountered Michael Davias’ and Tim Harris’ long contention that Saginaw Bay is an impact feature. And that 10 kps is a lowball conservative value. This is more likely to be the point where the extraterrestrial object struck because ejecta always radiate from the point of impact. If the unit stress from the impact exceeds the material’s yield strength, the material fails – i.e., it comes apart. Only the big ones – the early ones found – got both names and numbers, and a 2-digit number is notable.
