There are lots of slightly varying accounts of missing islands, lost continents, and lands forgotten to time.
At the same time there are many theories which purport to suggest their existence as well as the explanation for numerous other phenomena such as megalithic sites in alignments and arrangements.
Religions all speak of various levels of chaos in the past, and most speak of most recently the great flood and some discuss how lands were destroyed etc.
Then you have flat Earth with its theories which stretch from completely made up to plausible and reasonable questions to ponder especially when it comes to the space flights, NASA etc.
Pole shifts etc need to be accounted for in the discussion as well for it's relatively common threads and discussion points that tie in.
Some Brought in architecture and tartarian stuff alongside others which also comes in with their own theories.
Most recently I was made aware of VoC and their explanation for the expanded world alongside crater earth which provide additional thoughts.
So putting that all together ....
Where are hidden land, please put any links you have and put forward any theories you like, because we know there are definitely some.
I recently tried to find some of the older content I had seen and was unable to relocate it (mostly related to grid alignments and historical math geomancy)
What happened to California prior to the 1800s? It was an Island. Today its inland peninsula is a desert. The sea, waterway, has completely rejoined the mainland.

What happened to all the supposed Archipelagos connecting Australia to Asia?

Outside of the vastly different countries of detailed terrain today.
Was it simply cartography? Or was there worse tectonics then?
Another unheard of was a huge inland sea, massive lake detailed by Herodutus stretching from the Nile to Libya. Lake Moeris in particular. I won't link. Research it. There is only controversy and of the Labyrinith that once sat there.
Aside from this the water/ocean levels have increased in the last 100 thousand years.
There are quite a few more. If you wanted a disappearing Island. One further off Ireland springs to mind in the Atlantic. Detailed on heaps of maps, more or less gone today. Explanation of the plates, where in the Atlantic, it contains the biggest underwater mountain range on the Planet.

100000 years eh....you remember??
Lmao.... anything beyond 2000 years is made up...the last 2000 is murky fucking waters...
All your assumptions that lead to 100k years were created in the past 100 years...
