#geoglyphs — Public Fediverse posts

@rogue_corq
That's a false statement.
The number is an estimate and should not be in the title.
Nature should know better.
Over 400 were found, itself a big deal.

Not 30,000 found. Hundreds found and the recent lidar survey was used to estimate the possible number of earthworks.

V2025.08.01 updates online, now 1,450 #geoglyphs and zanjas recorded. The 2024 and 2025 hi-res satellite imagery surveys were productive. Also revealed, plowed and damaged geoglyphs. Pace of destruction has increased.

@UnconventionalEmma
Not evidence such a number exists, evidence some are hidden and just their estimate/inference. A lot of assumptions to arrive at that inference with a very flawed database (not one author noticed?).

One of the driest places on Earth, #Chile's Atacama Desert, attracts hundreds of racers every year - but the #offroad fun is also threatening - and destroying - #Indigenous peoples' rich #CulturalHeritage, ancient monumental #geoglyphs:

Some of the new geoglyphs identified on recent satellite imagery were already plowed when discovered. View them in Google Earth, download the KML file here:

But the even more important take away in all of this is: The #Nasca are so much more than these #geoglyphs!

There's been a lot of research about this whole ritual landscape, settlements, burials, and more in the #Palpa region:

https://www-dainst-org.translate.goog/en/research/projects/noslug/5685?tx_wfdaiprojects_projects%5Bnav%5D=open&tx_wfdaiprojects_projects%5Bsection%5D=results&cHash=c5bacb961e0c52001e097819eb71e24a&_x_tr_sl=de&_x_tr_tl=en&_x_tr_hl=de&_x_tr_pto=wapp

And since the #Nasca weren't the only ones leaving such #geoglyphs, but rather joined there predecessors in doing so, we even can see a #chronological development in their complexity:

We know about the "who" thanks to years of field research, excavations, and analysis - showing that the same designs used for these #geoglyphs are also appearing e.g. on #pottery vessels of the #Nasca:
