IIRC, one theory was that the reason it left no crater is because it impacted a glacial ice sheet.
One the glacier melted, any crater would have melted with it.
Methinks the reporter is misunderstanding things. AFAIK there is zero evidence the Clovis culture people were wiped out, only that their culture, supposedly based on the hunting of megafauna such as mammoths, disappeared when the megafauna went away.
The people presumably then altered their way of life to the point where they were no longer the "Clovis culture" people.
BTW, the traditional POV, now non-PC, is that the Clovis culture people and other early Indians wiped out the megafauna by overhunting, and possibly by "managing" the landscape with fire. I've always been skeptical of that notion myself, though I do enjoy watching it make liberals sputter. And the timing of the disappearance of megafauna all over the world does seem to have a close correlation to the appearance of humans in those areas.
The Clovis elected a socialist chieftain which led to their demise.
“Spelled doom to a group of early North American people.” The poor bas**rds had to sit through a spelling bee? No wonder they died.
Well obviously these humans polluted the atmosphere so much with their excessive CO2 emissions that the climate started cooling - just like is happening today ....

I'm not sure what evidence could be expected from a very low angle 3-4 km diameter bolide break-up moving South to North.
What astronomers stubbornly refuse to acknowledge is the static electrical charge differential between comets and meteors and planet Earth. They think that the Solar System is homgeneously electrically neutral while calling the Solar Electric Current the “Solar Wind” and the Van Allen plasma sheaths- “belts”. The Solar System is alive with electrical phenomena. 99% of all matter in the Universe is in the plasma state- ionized and electrically and, more importantly, magnetically, active. That’s what those pretty “nebulas” are made of and is what astronomers describe as “filaments” which stretch between galaxies as well as comprising their “arms”. These ubuquitous “filaments” are in reality plasma Birkland Currents.
It doesn’t take a rocket scientist to see that an approaching meteor can discharge violently at some point in the Earth’s atmosphere and shatter itself into much smaller components, as the evidence suggests at Tsunguska and as we witnessed at Chelayabinsk. Comets can also break apart (they are not “dirty snowballs”, but rocks just like meteors) and become a freight train such as Shoemaker-Levy 9, which can become a plasma torch creating a swath of plasma furnace temperatures burning everything and melting mountains like candle wax. http://sites.google.com/site/dragonstormproject/
Astronomers cringe at the possibility of one day having to admit that we live in a cosmic shooting gallery because our only defense, at present, is our Cold War nuclear ICBM arsenal, which would then take on the property of savant technology and the elevation of men such as Edward Teller to guardian angel status.
