Caral is an important site in the Supe Valley of central Peru near the coast and was part of the Norte Chico civilisation. It was occupied during the third millennium BC, although some push that back as far as the fourth millennium. Caral is claimed to be the oldest urban settlement in the Americas(a), although other sites in the region may challenge that. Arthur D. Faram has written a petroglyphic study of Caral(c).
A 2021 article from the History Channel suggests a date of around 2600 BC for the Caral complex and that it was abandoned about a thousand years later(d).
The 600-hectare site includes a pyramid complex that may have preceded those of the Egyptians. An early quipu was also found at the site suggesting some form of continuity with the later Inca civilisation.
In the 1950s, further south, in the Manchay Valley near the capital Lima, Karola Siebert was convinced that she had found Atlantean remains, while further south again, over the border in Bolivia we have Jim Allen’s chosen location for Atlantis near Lake Poopó.
A French website(b) has on offer the strange idea that the longitude of Caral in Peru and that of Xian in China and their respective relationships with the Prime Meridian at Greenwich and the longitude of Giza have some bearing on the location of Atlantis, which the author, Fabien Pardo, places in the Antarctic!
I reject all South American locations as possibly Atlantean and do so principally because the idea of an attack on Athens being launched from the west coast of South America, thousands of years ago, is, to put it kindly, just silly. However, it is quite clear that this region has had a fascinating prehistory and should keep archaeologists busy for generations to come.
The Hopi Indians, currently settled in northeast Arizona, are the descendants of the Anasazi who in turn are believed to have had links to the Aztecs.
Another site associates them with the Maya(b)(c). Several writers have tried to suggest that the Hopi had an early connection with Atlantis employing a highly subjective interpretation of their traditions and flood myths.
Thomas O. Mills, author of The Book Of Truth: A New Perspective on the Hopi Creation Story , offers the intriguing suggestion that there is a link between the Hopi and Egypt’s Valley of the Kings(e). For good measure, Mills has also claimed a Hopi connection with Stonehenge(f). and produced another short book, Stonehenge – If This Was East .
When Robert Bauval & Adrian Gilbert published The Orion Mystery  in 1994, we were happy to follow the ensuing debate on the reality of what became known as the ‘Orion Correlation Theory’ (OCT) and the large pyramids at Giza. Now, the proposed matching of the alignment of the stars in Orion’s ‘belt’ with the pyramids at Giza has been extended to include other structures around the world. Apart from Giza, one site(h) lists the Chinese Xi’an Pyramids, the Teotihuacan Pyramids in Mexico and, unexpectedly three Hopi Mesas!
Gary A. David has endorsed the Hopi alignment, incurring an accusation of dishonesty by Jason Colavito(g).
Others have associated the Hopi with UFOs and the supposed disasters that were due in 2012.
One of the traditional Hopi tales points to a sunken land in the Pacific, Kássara, as their original homeland, which they had to flee as it began to slowly sink(i).
There is now a website(a) dedicated to the Hopi and their petroglyphs as well as a number of other related papers from Gary A. David. In one(j) of which he proposed that the Hopi had their own Orion Correlation tradition displayed over 200 miles on the Colorado Plateau where according to David “either an ancestral Hopi ruin or an inhabited Hopi village directly corresponds to each major star in Orion.” David also returns to Egypt where apart from the Giza OCT, advocated by Bauval and Gilbert, he claims that some of the stones of Nabta Playa also seem to Correlate with Orion citing the work of Thomas Brophy .
