I found this interesting and thought others might think so too.

Researchers are finding all sorts of new stuff out about Mayan civilization. Using LIDAR in the jungles of Guatemala, they have found over 60,000 unknown structures. Also canals, dykes, reservoirs, and other complex irrigation and travel systems including roads and bridges. This suggests that the area could have harbored millions of residents.

They have also just found vast underwater caves linking many of the cenotes. These new caves span vast distances and are full of all kinds of extinct megafauna, human remains, and other strange things. I'd really like to see pictures and descriptions of everything they are finding, but they aren't letting many details and pictures out.

Real awesome info, always was interested in Mayan history, and what happened to them

Saw a show on The Travel channel about this.
Some guy (Josh Yates?) went down and investigated. He went diving in the underground caverns and they were huge.
They found what looked like sacrifices and lots of pottery underground, actually underwater because they believe there was a drought at that time.

I hadn't heard of the caves before, must be limestone there, cool info

Cool Stuff...makes a guy wonder at the age of the Earth.

I knew Aztec people did sacrifices, but didn't know Mayans did too, used to read about them years ago in school

For more in depth information on this subject try this book 1491 by Charles C. Mann.

Excellent read. Particularly interesting with respect to New England's millions of dead natives and grave robbing English folk.

I saw another article were they may have found the vector that killed off 80% of the population. They are pretty sure it was a European strain of course.

I've fished between Tulum and Belize a lot over the years and they built some amazing stuff indeed. They had ways of navigating the reefs at night using small fires on top of their temples for boats to find the safe passages from well offshore. I've seen one of the rocks they would use to bend a person over to cut out their heart for sacrifice.

No doubt it was a huge civilization.

Less than 50 years for the Spanish to reduce 30 million Mexicans to less than 3 million. No single vector, all European diseases were devastating to the indigenous peoples. Of course when a town was dying it was natural to send a messenger to neighboring towns and yes the messengers carried the sickness along with the news.

Based on a few other discoveries around the world, I will not surprised if they discover it to be an earlier civilization that predates the Inca and Mayan peoples

Show 1.9 must be the one i watched.

They’ve also figured out that it was likely a form of salmonella that wiped most of
Them out.

Funny thing is they found an old crushed up can a Mountain Dew buried with that stuff. The Mayans invented it a bajillion years ago. Makes sense

Yes Sir Tac.20 about limestone in the area! Most of the Yucatan peninsula and parts of Belize and Guatemala are flat as a pancake and made up of limestone. There are no rivers or creeks that flow through the Yucatan and other similar areas. As far as we know, the Mayan folks that lived there relied on the underground rivers and cenotes which contained fresh water in order to sustain them.

Thank you cpizzcharlie and tjm. I just bought that book on Amazon, and looking forward to reading it!!

I spent 2 months studying about central America while living in the Yucatan and have never heard of that book.

That's sure different, couple caves in se MN, limestone there, many sink holes by Harmony, MN ,
I forget, were the Mayan's gone before the Spanish came?

Yup seen that on Sci channel. I think it's called Secrets of The Underground or Mystery of the Missing or something like that. I like that show.

Pete,

I know what you are talking about. I've seen those places to and now it gives me a lot of pause.

I've been to Chichen Itza and Uxmal. It was back in the day though when they still let you climb the pyramids. I was young and dumb back then, and remember puffing a cigarette while on top of those pyramids........the things that don't cross your mind when your are young.
