Wonderful video I just found of the Floating Gardens in Mexico City
How Mexico City's Mysterious Floating Gardens Helped Feed the City For Hundreds of Years
"A look at Mexico City's floating gardens, also known as the Chinampas, which were created by the ancient Toltec tribe. To this day, area farmers work tirelessly to preserve and cultivate the canals and their floating farmland to provide produce and fish for the city's most well-known dishes."

I was not familiar with these gardens, so I learned a lot.
Thank you for your posts. I usually read all of them and watch the attached videos.

Photo taken to put in device for holding up to one's eyes, so each eye sees one photo, like stereo. Pretty old!
painting of someone's idea of early days of xochimilco. Looks as if the artist imagines the elites wore hospital gowns! Little breezy in the back.

had no idea of how important they actually are to Mexico City. I saw them as groomed flower gardens. Thank you for giving me the bigger picture, Judi Lynn! 
Permaculture:

Had no idea. Have been reading for a few years a ibout the land culture used by original people of the Americas, after reading "An Indigenous Peoples' History of the United States (REVISIONING HISTORY) Paperback – August 11, 2015
by Roxanne Dunbar-Ortiz "
Of course, brought up completely in the dark after all the public school history lessons, I had no idea that the original people carefully tended forests, waters, and flatland where they lived for eons, before it was stolen, and sometimes turned out like Oklahoma during the Dust Bowl.
You have illuminated at least one person who read this thread, and "permaculture farmette" does fit the situation perfectly!
Thank you.
But they're built on fill resting on the shallow bottom of the lake. There are floating islands in other places in the world such as the inhabited islands of Lake Titicaca in Peru.
Somewhere in there is an Island of the Dolls
The Island of the Dolls (La Isla de las Muñecas), located in the channels of Xochimilco, south of the center of Mexico City, very close to the Estadio Azteca football stadium, is a chinampa of the Laguna de Teshuilo and one of the main attractions of the channels. Dolls of various styles and colors are found throughout the island, originally placed by the former owner of the island, Julián Santana Barrera. He believed that dolls helped to chase away the spirit of a girl who drowned years ago. He died in 2001 of a heart attack. Sources say he was close to the same spot where the girl drowned.[1]
