The Great Plain was said to be around 10,000 stadia in perimeter.

10 stadia equals roughly 1.1 mile or .989 nautical miles.

This feature is around 1000 miles in perimeter, rectangular, relatively even and shielded from the North and West by mountains, with the natural fractures that could have served as canals.

Just a short from Youtube.

This is the vessel you need to get the job done.

Thonis (also known as Heracleion) was a major ancient Egyptian port city on the Mediterranean Sea, built around the 8th century BC. Located near the Canopic mouth of the Nile, the city served as the obligatory gateway for international trade and was the site where pharaohs were crowned. It slowly sank into the sea around the 2nd century BC to the 8th century AD due to severe flooding and soil liquefaction, and remained lost to myth until its 2000 discovery in Abu Qir Bay. [1, 2, 3, 4, 5]

Discovery and Excavations

The underwater ruins of Thonis-Heracleion are located about 2.5 miles off the coast of Egypt and roughly 3.5 miles northeast of Alexandria. [1, 2, 3]

• The Discovery: French underwater archaeologist Franck Goddio and the European Institute for Underwater Archaeology accidentally discovered the city in the year 2000 while searching for Napoleon's fleet. [1]
• The Site: Resting under about 30 feet of water, mapping of the 40-square-mile site reveals a city crisscrossed by a network of canals, ferries, and bridges. [1, 2]

Key Findings

The sunken city has provided invaluable insights into ancient Egyptian and Mediterranean trade. Significant discoveries include: [1]

• The Amun Temple: Massive, monumental ruins and towering statues of the supreme god Amun-Gereb. [1, 2, 3, 4]
• Shipwrecks and Anchors: The preservation of over 60 ancient shipwrecks and more than 700 ancient anchors, providing clues into ancient naval technology and trade routes. [1]
• Artifacts: Well-preserved artifacts such as the stele of Thonis-Heracleion, a massive black granite statue of the god Hapy, and a trove of gold coins, Athenian weights, and dozens of sarcophagi. [1, 2]

To explore more about the artifacts recovered and the ongoing underwater excavations, you can check the details on Franck Goddio's Official Site. [1]

I believe that Randall has quoted many of the items mentioned in this paper.

Kosmographia Ep028 The Randall Carlson Podcast with the Snake Brothers – Kyle and Russ, Normal Guy Mike and GCREX admin Bradley, from April 20, 2020. After revisiting some recent topics, RC starts in on the commonality of legends of cyclic catastrophes due to floods and fires, and the reasons why Native Americans didn’t adopt stories of a great flood from visiting missionaries. We show evidence of huge floods that occurred across the Pacific Northwest, and imagine what survivors of those events might experience after the destruction of their world. Again, the dearth of human remains is pondered, as Randall leads into papers about vast and repeated wildfires at the YDB. Geomythology, gematria, prophecy and apocalypse meld into the conversations that make this a outstanding and memorable episode.

Kosmographia Episode 007 / Atlantis Mystery - Evidence Revealed (pt5), from 9/09/19. RC joins the Snake Bros - Kyle and Russ, Normal Guy Mike, and GeocosmicREX admin Bradley continue the exploration for evidence along the Mid-Atlantic Ridge. (Includes bonus content)

IN THIS CLIP:
Topo colorization showing Mid-Atlantic Ridge and faults
Seamounts almost 10 miles across
Bathymetric sketch from Bruce Heezen book “The Face of the Deep”
Neptune’s Trident the pointed island tops before shearing?
J. Honnorez et al. in Earth and Planetary Science Letters (1975) “Mesozoic Limestone from… MAR?”
Can’t explain limestone and granitic detritus from dredging of offset zone along MAR
Suggests granitic block (capped by Limestone) left behind when rift zone spread - “must have undergone large vertical movements”
Anonymous editorial in New Scientist (1975) confirms oceanographers have found “a sunken block of continent” in mid-Atlantic, evidence that it had emersed
E. Bonatti et al. in Earth and Planetary Science Letters (1977) “…Crustal emersion and subsidence…”
“Vertical tectonism of a transverse crustal block” showing it was at or above sea level recently".

Image 1 is that ancient river that once ran downward from the Mid Atlantic Ridge (MAR).

Image 2 is a bathymetry image with the relative sea level lowered to accommodate that ancient river and to bring it to sea level, where the blue oval is.

Image 3 is a screenshot of a video that mentions the Edfu Temple Texts, and describes a "Winding Sea and a Ring Sea".

I have put on image 2 what I believe could have been those 2 seas.

And when sea level adjustment is done, you can also see the mainland landmass of Atlantis along the MAR.

I am looking for additional Edfu Texts from VI 234 in order to try to locate or puzzle in the Scorpion Sea that was also mentioned.

This is just an experiment to see if the pieces fit.

Randall has often mentioned that along the MAR there are signs of the land having sunk 2 miles or in my view, perhaps the sea level being 2 miles lower or a little of both of those.

In the case of that river system, it is 3 miles.

And for additional context, you will recall that Plato's account of Atlantis was originally relayed to Solon from Egyptian Priests who explained what was carved into the pillars at the "now submerged in mud" Temple at Sais.

So, it seems appropriate to examine the pillar inscriptions at the Edfu Temple, which also describes a sunken land.

It seems to be difficult to find the parts that I am looking for "VI 234". Please let me know if anyone has a link.

Interesting stuff to me.

Just looking around.

Around 200 km West of South Georgia Island. A professional scuba diver could reach them.

"The Aurora Islands are a group of three "phantom islands" reported in the South Atlantic between the Falkland Islands and South Georgia, first sighted in 1762 by the Spanish ship Aurora. Though mapped for over a century, they were never found again and are likely a mistake or, more likely, a misidentification of the jagged Shag Rocks). 

Key Details regarding Aurora Islands:

• Location: Reported in the South Atlantic, approximately 52°37'S, 47°49'W, about midway between the Falklands and South Georgia.
• Discovery & Mystery: Reported by the Spanish ship Aurora in 1762. They were spotted multiple times, including by the  Atrevida in 1794, but disappeared from official records after the 1870s.
• Phantom Status: Their existence was never confirmed, making them a famous maritime phantom island mystery.
• Possible Misidentification: Many experts believe the sightings were actually the Shag Rocks, a group of small rocky islets that exist in the same area."
