I have been listening to this lecture series about the colonization of the Americas, and how the Mayans were unprecedented for being able to carve out an advanced civilization in an inhospitable, under-resourced jungle without the benefit of the wheel, plow, and draft animals (the lack of the latter is why the wheel never came to use as a tool to begin with).
Now, scientists using advance laser technology have revealed the incredible extent of the Mayans’ achievements: sophisticated urban complexes spanning tens of thousands of structures deep in the jungle. As IFLS reports:
Archaeologists first discovered the vast metropolis in February, National Geographic reported, led by Guatemalan science nonprofit group the PACUNAM Foundation. Publishing their work in Science over six months later, the team confirms the presence of more than 61,000 ancient structures, including houses, large palaces, ceremonial centers, and pyramids.
LiDAR pierces through the thick forest canopy to reveal changes in elevation, allowing the researchers to identify these topographical features as manmade walls, roads, and buildings without ever having to set foot on the ground. With this information, they are able to create three-dimensional maps in a matter of minutes, avoiding years of arduous fieldwork.
Seen as a whole, terraces and irrigation channels, reservoirs, fortifications, and causeways reveal an astonishing amount of land modification done by the Maya over their entire landscape on a scale previously unimaginable,” explained team member Francisco Estrada-Belli in a statement.
In all, more than 61,000 ancient structures have been accounted for in the surveyed region, indicating that up to 7 to 11 million people were present at the height of the Late Classic period, 650-800 CE. For scale, New York City has about 8.5 million people. These populations were unevenly distributed with different levels of urbanization and were spread out over more than 1,200 square kilometers (810 square miles). This land was modified in some way for the intensive agricultural production needed to support the massive population for hundreds of years.
“It seems clear now that the ancient Maya transformed their landscape on a grand scale in order to render it more agriculturally productive,” said Maya archaeologist Marcello A. Canuto. “As a result, it seems likely that this region was much more densely populated than what we have traditionally thought.”
Whether or not these structures existed at the same time, or represents different periods of development, it is still amazing that such large and well organized societies could have sustained themselves in environments that even today are challenging to settle and develop.
