In a fiction book I am writing Sundaland is the basis for Mu. Based upon my research, Mu was the “Mother” culture, much like Churchward’s work, that had spread outward, first west, then east. The culture spread east to the America’s and eventually centered in Atlantis, while another faction spread east through Burma into India and beyond to the Med and Europe.
In my story, it is a civil war, with Atlantis faction fighting the proto-Greek faction. The end of the ice age arrives with the original Mayans succumbing as well as Atlantis.
This is not the thrust of the story, but part of the back drop of the history of man. Mankind as we know him has been around for at least 180K
years. Before that, who knows. Well, we do know that other humans walked the planet, just not homo sapiens.
The end of the ice age is perplexing indeed. It was a process that began around 12875 b.c. and culminated with a major bang around 11600 bc, according to the geology and Plato. There are other events after, such as the Berkle Crater that might account for the events 8000 years ago. (Noah’s Flood)
North America specifically the United States was catastrophe central as the ice pack sitting along out northern regions and the whole of Canada created some fantastic flooding events when was instantly melted.
I am having problems with figuring out the process. Every story likes a dramatic scene and if the end of the ice age was a 1400 year event, it is not so dramatic as say an earth wide flood and volcanos and comets and the stars falling on one’s head, so I may have to take a bit of license and do away with the geology.
If I ever get this one finished, I will let you know. It is the third in a series of stories that actually features a young girl and her two-headed turtle. Don’t ask me how it all fits, but it does. And that very same two-headed turtle is sitting in their tank just feet away. Probably sleeping at this time of night.
Anyway, your story sounds interesting, let me know when you finish it.
Sundaland would have been a perfect place for humans to thrive through-out the whole Ice Age. There was a lot if 'shifting' going on (earthquakes, volcanoes, tsunamis and etc.) due the weight of the ice and then again as it melted and released the stress. The Tibetens have stories of mountain topping waves...those have an origin somewhere, eh?
Good luck.
