“araona crater” “iturralde structure”
crater bolivia jungle
It was originally called Iturralde, then a preliminary expedition found that the Araona Tribe lived there, so they named the crater after them.
Dating is not exact yet, though there have been two expeditions, it’s very remote and heavily vegetated and there is not much land data to play with.
I'd go myself but I'm not sure I want to start dating again.
I don't believe that the impact you describe would be relevant to the theory put forth in the article, as interesting as it may be.
Fact is, it's in Bolivia, well south of the equator.
While there is some cross-over of weather patterns over the equatorial zone, the majority of any weather effects of a Bolivian impact would show up in the southern hemisphere, not the north...
Additionally, the science writer of the article I read from Space.com tries to imply that a bus-sized meteor resulted in an explosion of several Mega-tons..
Bus sized ? Kilotons, maybe.. Definitely not megatons.
I'm guessing this impact crater is not big enough to have caused the sort of damage and effect the "diamond dust" article proposes, even if it had actually been in North America.
It will be interesting to see what info they come up with, however, and what theories may be advanced as to how it effected the flora and fauna of South America or it's Pacific coast.
In my own opinion, even 30,000 years is not too early for possible human occupation of the South American continent.
That would not be too early for the Australian aborigine travelers believed to have inhabited South America well before the Bering Straits migrations.
There may well be some rock paintings of some sort at the far range of that impact. ( 500 miles or more )
