Large Impact Crater in North America? Image now available.

[funkyvudu]

Picture now posted!!!... Scroll down to satellite image of the North American continent. There appears to be a massive impact site in Northwestern America. Impact site appears to be about equal in size to Oregon. Thanks for any interest or opinion.

Photo still pending , but if it is the nice round shapes found east of yellowstone, those are super volcano craters. Yellowstone being the volcano, plus the plate movement. <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

I may have highlighted that in the picture. But I am thinking on a much bigger scale. The crater I think I see is towards the Northwest & about the size of Oregon.

Found this in Google Earth. It is roughly 50 miles from here.<br /><br />{it really isn't a crater, but pretty weird just how circular it is}<br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

The largest impact crater in NA, according to what I could find, is the Chesapeake Bay impact crater. It's about 3.5 million years old, about 85 km in diameter and 1.3 km deep. <div class="Discussion_UserSignature"> <strong><font color="#3366ff">Made weak by time and fate, but strong in will to strive, to seek, to find and not to yeild.</font> - <font color="#3366ff"><em>Tennyson</em></font></strong> </div>

I'd be interested in seeing a composite of all known impacts across the earth, and thier time frame, to see if any overlap. <br /><br /> We always seem to try and say "its was one big impact" for cataclysmic meteor impact events, but i have a feeling at least one of those may be where earth got buckshot, so to speak. <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

THIS IS THE PICTURE I HAD INTENDED TO POST AT THE BEGINNING OF THIS DISCUSSION FORUM.<br />To me I see the marks of a massive impact crater. I have highlighted what seems to be a circular pattern to me. Maybe it's just wishful thinking, but this feature seems to possess many of the same marks as other massive craters in our solar system. The yellow circle in the center is where it would seem an impact took place. Along with smaller impacts that may have been "buck-shot" that came with the main object. The red rings could represent a second ring or ray pattern & further out an ejecta pattern??? What do you think? Thanks!

 

[funkyvudu]

My apologies... will delete & repost a smaller file.

Not exactly what i was looking for , thanks though.

Hey, I'm still working on it.

[enigma10]

that map is kind of scary if you look at where most have struck. Those are just the land based ones , from what i can tell. ocean ones would be near impossible to discover.<br /> <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

Also it is worth remembering that these are the KNOWN sites. I understand that there are several large craters under the ice on Antarctica. <br /><br />We have one (The Silverpit Crater) in the North Sea off the east coast of Britain.<br /><br /> <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

A few points on the map.<br />You notice there are no deep ocean craters shown.<br />Also, there are deficits in mountainous regions.<br />This would be both affected by the rapid recycling and distortion in these regions, as well as huge difficulty in gathering data. <br />Mountains rise and twist and quake, mid-ocean ridges push the ocean surface until they subduct at the edges of continents. In the big picture, both of these processes are "rapid".<br />Notice the large concentration in Europe. <br />Much of the modern science of the last few hundred years started there. Before then, people did not even believe rocks could fall from the sky, since it was a big clear ball around us.<br />Modern science in North America is only two hunded years old or so, and the data from the original inhabitants is in a form hard for us to access.<br />See how many there are in Australia. These are mostly the efforts of Gene Shoemaker (as are all the craters on the moon, since before him, no one thought they were impact craters.)<br />So as stated, these are known craters. <br />The only logical position is that the distribution of impacts across the earth is an even layering. <br /><br />Since the cratering is different on the side of the moon facing us compared to the other side (due to the earth's gravity attracting more objects of different sizes after the moon became tidally locked to the earth) you could look for a similar effect, however since the earth rotates relative to the sun, and that rotation rate has chnged, that seems unlikely.<br /><br />So, don't panic! No matter where you are on the earth, you're just as likely to be whacked as anyone else!<br /><br />The only folks in more danger are those near the coasts of the world (what is that, 50% of the earth's population?) who could be swamped by an oceanic impact, causing a tsunami. Earth is more than 2/3 ocean, which means more than 2/3 of the impacts occur there.<br /><br />Don't worry, as we keep looking, the map will even out more : <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

MeteorWayne... Any thoughts on the satellite image I posted of North America? Looks like a large impact site to me... Any input is appreciated.

 

[MeteorWayne]

Well, it certainly is a provocative idea!<br /><br />With the lines drawn in your diagram, I could see the discontinuities being there, at least for the two inner rings.<br />The third ring is less clear, but that would be expected at the outer edge of a triple ring system (see the gravity maps of Chixalub.) One must also consider the tectonic origin and activity of the continent, so even though something is there, an impact may not be the only solution. However it is an intriguing idea.<br /><br />I am no expert on recognizing extremely ancient impact craters. <br /><br />Can I ask about the map? I assume this is a vegetative map of North America. Could you post the original image (with permission) without the rings drawn in to see how the pattern shows up without them? I mean, the concept will still be in my mind, but I'd like to see the raw image.<br /><br />MW <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Here is the original true color image of North America... Thanks for the interest.

 

[MeteorWayne]

funkyvudu,<br /> Well I would say the to me, inner ring shows up pretty clearly.<br />What that means is harder to say.<br />Remember, the human brain is hard-wired to see patterns, even when one is not there (See the Face on Mars fiasco.) So what we are looking at may or may not be real. In any case it is worth further investigation.<br />The outer rings are much more difficult to see, and appear to align with what are likely unrelated features caused by the edge of, and the formation of, the North American plate (Cascades and Rockies.) However, as previously stated, outer rings would be much less distinct, even if they are related.<br />Sorry it took so long to reply, but I've been poking around to see what the vegetative changes are that we are seeing as the border of the inner ring. It's not easy <br />Have you done any research on that?<br />It looks like the dark line on the northeast may be the Missouri River valley in Western Montana, but I'm not sure. Is it possible the river followed the edge of an ancient crater? I must admit I don't know.<br />Like I said, it's a bit hard to identify what feature represents what.<br />I'm working on it, currently using a world atlas.<br />Let me know if you have any ideas on what the borders are of the inner ring.<br /><br />MW <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Hasn't someone proposed that Hudson's Bay is an impact site? <div class="Discussion_UserSignature"> <em><font size="2">Bob DeWoody</font></em> </div>
