This fellow, Richard Hansen, has done much to uncover long-lost Mayan civilizations. Read the article here.
As a grad student, Hansen made a significant contribution:
“The gigantic El Mirador complex had first been discovered in 1926, and it was assumed that owing to its sheer size and elaborate layout, it represented yet another classic-period city like Tikal, only in worse condition.
But while excavating a chamber in the bottom level of a structure at El Mirador known as the Jaguar Paw Temple (the jungle cat had totemic significance for the Maya), the 26-year-old Hansen came across fragments of polished-red pottery, undisturbed for centuries, that could only be preclassic in origin. “That ceramic was only produced in the Mirador Basin, and I was the first one who identified that,” he says.
It was a startling moment of revisionism: It meant that the entire El Mirador agglomeration dated at least five centuries earlier than anyone had thought, to a period that began before the time of Christ, and that the preclassic Maya, rather than being primitive forerunners of a more elaborate classic civilization, had built far bigger and produced an even more complex and powerful political and social organization than their medieval successors—until they, like their successors, precipitously abandoned their massive settlements during the middle of the second century. “
Hansen’s freedom from the strictures of academia also helped him become one of the very first archaeologists to exploit a brand-new technology that has been to Mayanists of the second decade of the 21st century what carbon-dating was to the Mayanists of the 1950s: light detection and ranging, or LiDAR. The technology—using airborne lasers to “map” the topography of a given area digitally, revealing the natural peaks and valleys, as well as manmade structures, beneath the dense jungle canopies that otherwise mask them—had been used for decades by NASA to create digital maps of planet surfaces.
