Clarify for me, please. Am I correct in concluding the Rio Cuarto impact was off of South America? And the later impact (1150 BC) was the more familiar Yucatan strike?
And is there a discernible fit with the underwater city off the western tip of Cuba?
A string of linear depressions characterizes the Rio Cuarto crater field
In the January 16, 1992, issue of Nature, P.H. Schultz and R.E. Lianza describe a curious chain of grooves incised in the Argentine pampas near Rio Cuarto.
"During routine flights two years ago ..., one of us (R.E.L.) noticed an anomalous alignment of oblong rimmed depressions (4 km x 1 km) on the otherwise featureless farmland of the Pampas of Argentina. We argue here, from sample analysis and by analogy with laboratory experiments, that these structures resulted from lowangle impact and ricochet of a chondritic body originally 150-300 m in diameter."
There are ten gouges in all, strung out along 50 kilometers. The scars are young, perhaps only a few thousand years old, well within the time of human habitation. Schultz and Lianza also found pieces of meteoritic rock and glassy fragments of impact melt.

Comments. Note the similarities to the much more numerous Carolina Bays. See ETB1 in our catalog: Carolina Bays, Mima Mounds, Submarine Canyons.
The Yuchatan Strike was named Chixlub(sp) and was 65 millions years ago. The dino killer, it was.
"And is there a discernible fit with the underwater city off the western tip of Cuba?"
Glad you asked. I found this while looking for support for my theory about the underwater Cuban city. It occurred to me that 2200 feet is a lot of subsidence, so I have proposed that the Gulf Of Mexico was blocked off (like the Black Sea) during the last Ice Age and dried up to some stable level and these people actually built this city/structures on the coast of the lowered Gulf of Mexico.
I was looking at some underwater data and saw some curious round depressions just south of the Bahamas and went looking for impacts that may have broken the 'dam' to the Gulf of Mexico. I came across this article in my search, which lends some support to impacts in the region.
For which I earn a great, big "Duh!"
Thanks very much for all the info. The global relief map is incredible. But I'm still waiting for it to download (28.8 ISP)...
That date is a fascinating one, as it predates the emergence of Abraham from Ur in the Chaldees by only a hundred years or so. Something was clearly going on...
Is it that really big file that crashed my P60? If so, I have seen about half of it. Most impressive.
I can hardly wait for the next Ice Age so I can walk out to the edge of the continental shelf and excavate lost cities.
Wonder what the weather was like with oceans so much smaller? Has anybody thought about this?
