Lidar Finds Overgrown Maya Pyramids 169
AlejoHausner writes "A team of archaeologists scanned the jungle of Belize with lidar. Although most of the reflections came from the jungle canopy, some light reflected off the ground surface. Using this, suddenly hidden pyramids, agricultural terraces, and ancient roads are revealed, at 6-inch resolution. The data allowed the archaeologists to bolster their theory that the ancient city of Caracol covered more than 70 square miles of urban sprawl and supported a population of over 115,000."

Great thought, but the time to process lidar data takes a while. So planes and objects sure, but even the logistics to get this done takes time. Not sure about people, due to resolution over a vast area and again logistics. The bare-earth relief (which strips away a degree of vegetation) lidar offers is incredible. Cartographers and geologist have only recently really taken advantage of the technology. But in time and $, these other uses could definitely be considered, especially when resolution and processing is more developed.

You mock, but the discoveries of megalithic structures over the past twenty years have called into question a lot of our assumptions about the earliest civilizations with technology. There are rock carvings being discovered in the Southern part of Africa that show very advanced understanding of astronomy, geography and time measurement that appear to be over twenty thousand years old which is much, much earlier than previously thought.
If we can ever get scientists to be able to really research the pyramids and nearby structures without the dictatorial control of the Egyptian government, there is reason to believe that there are references to sophisticated understanding of astronomy going back over fifty thousand years.
When I worked at the University of Chicago, I used to hang with people from the Oriental Institute. From them, I learned just how shaky a lot of the theories regarding Early Egyptian culture really are, including but not limited to how in the hell the pyramids were built. One of the foremost Egyptologists in the world once confirmed to me that the accepted theories are clearly ridiculous, that the notion that you can drag, or roll on logs, granite blocks weighing up to 100 tons for several miles, and then erasing every sign of the way in which they were moved, is just nonsense. Further, he'd like to know, how in the hell were they able to move those stones over 100 feet in the air to place them at the top of the pile?
This gentleman, now dead, explained that Egyptology specifically, and archeology generally, are so political that any theory or work done outside the mainstream is killed before it can even be peer-reviewed. This guy, a professor emeritus at the time, told me he'd had a 20 year correspondence with crypto-archeologist Graham Hancock and he was careful to tell me that though he disagreed with most of Hancock's assertions, that some of them deserved much closer consideration. And it's not only academic politics that have shaped our "consensus" regarding those civilizations. Religious and political forces have played an even greater role in making sure that the accepted history supports certain orthodoxies.
Atlantis? Well, probably not, but once you get past 50,000 years it's not at all impossible that there was a relatively advanced civilization on this planet that subsequently disappeared.
