From National Geographic:
Hidden for centuries, the ancient Maya city of Holtun, or Head of Stone, is finally coming into focus.
Three-dimensional mapping has "erased" centuries of jungle growth, revealing the rough contours of nearly a hundred buildings, according to research presented earlier this month.
Though it's long been known to locals that something—something big—is buried in this patch of Guatemalan rain forest, it's only now that archaeologists are able to begin teasing out what exactly Head of Stone was.
Using GPS and electronic distance-measurement technology last year, the researchers plotted the locations and elevations of a seven-story-tall pyramid, an astronomical observatory, a ritual ball court, several stone residences, and other structures.
The Maya Denver?
Some of the stone houses, said study leader Brigitte Kovacevich, may have doubled as burial chambers for the city's early kings.
"Oftentimes archaeologists are looking at the biggest pyramids or temples to find the tombs of early kings, but during this Late-Middle Preclassic period"—roughly 600 B.C. to 300 B.C.—"the king is not the center of the universe yet, so he's probably still being buried in the household," said Kovacevich, an archaeologist at Southern Methodist University in Dallas.
"That may be why so many Preclassic kings have been missed" by archaeologists, who expected to find the rulers' burials at grand temples, she added.
The findings at Head of Stone—named for giant masks found at the site—could shed light on how "secondary" Maya centers were organized and what daily life was like for Maya living outside of the larger metropolitan areas such as Tikal, about 22 miles (35 kilometers) to the north, according to Kathryn Reese-Taylor, a Preclassic Maya specialist at Canada's University of Calgary.
Head of Stone, which has never been excavated, "was not a New York or Los Angeles, but it was definitely a Denver or Atlanta," said Reese-Taylor, who called the new mapping study "incredibly significant."
From about 600 B.C. to A.D. 900, Head of Stone—which is about three-quarters of a mile (1 kilometer) long and a third of a mile (0.5 kilometer) wide—was a bustling midsize Maya center, home to about 2,000 permanent residents.
But today its structures are buried under several feet of earth and plant material and are nearly invisible to the untrained eyed.
Even Head of Stone's three-pointed pyramid—once one of the city's most impressive buildings—"just looks like a mountain enveloped in forest," said study leader Kovacevich, who presented the findings at a meeting of the Society for American Archaeology in Sacramento, California...
