This archive covers progress stories from North and Central America, spanning the U.S., Canada, Mexico, and the nations of Central America. Readers will find reporting on health, environment, community resilience, and policy advances across the region.
The Pyramid of Kukulcan rose at Chich’en Itza between 800 and 900 C.E., built by Maya hands as both temple and working calendar. Its four staircases hold 91 steps each, plus the top platform — 365 in all, one for every day of the solar year. A civilization writing mathematics into stone.
Teotihuacan, in the highlands of central Mexico, was the largest city in the Americas around 450 C.E., home to roughly 100,000 people drawn from Oaxaca, the Gulf Coast, and the Maya region. Its planned grid, towering pyramids, and obsidian trade reached across Mesoamerica. Nearly a thousand years later, the Aztecs still made pilgrimages to its ruins.
In 426 C.E., a warrior-king named K’inich Yax K’uk Mo’ arrived in the Motagua River valley and founded the royal dynasty of Copán in what is now western Honduras. His line endured nearly four centuries, producing at least 16 rulers, a 2,200-glyph hieroglyphic stairway, and astronomical calculations of the Venus cycle that still astonish modern researchers.
The Thule Tradition took root along Alaska’s Bering Strait coastline around 200 B.C.E., when ancestors of today’s Inuit and Yupik peoples began crafting kayaks, umiaks, and harpoons sophisticated enough to hunt bowhead whales. From those windswept shores, their descendants would eventually spread across the entire Arctic, reaching Greenland by the 13th century.
Teotihuacan began taking shape around 200 B.C.E., when farming villages near a cluster of reliable springs in a high valley northeast of modern Mexico City started merging into something bigger. At its peak, the city sprawled across eight square miles and held an estimated 100,000 people — quietly becoming one of the ancient world’s largest urban experiments.
Monte Albán rose around 500 B.C.E., when Zapotec-speaking people flattened a mountaintop above Oaxaca’s three converging valleys and built one of Mesoamerica’s first true cities. Over the next few centuries they developed one of the Western Hemisphere’s earliest writing systems, carving conquests into stone. Their descendants still live across Oaxaca today.
Dorset culture took shape around 500 B.C.E. across the Canadian Arctic, enduring nearly 2,000 years without bows, dogs, or many tools their neighbors relied on. They hunted seals and walrus through holes in the ice, lit the long darkness with soapstone lamps, and carved miniature masks still counted among the Arctic’s finest ancient art.
Olmec civilization took shape along Mexico’s Gulf Coast around 1200 B.C.E., raising cities, planned plazas, and colossal basalt heads in the humid lowlands of Veracruz and Tabasco. At San Lorenzo, builders hauled portrait stones weighing up to 8 tons across dozens of kilometers. Much of what later defined Mesoamerica — pyramids, ball games, even ceremonial chocolate — begins here.
Poverty Point culture, flourishing along the lower Mississippi around 1500 B.C.E., built six concentric earthen ridges, a 50-foot pyramid, and a bird effigy mound near present-day Epps, Louisiana. Its people traded for copper and stone from sources up to 620 miles away, quietly proving that complex society took root in North America far earlier than once assumed.
Greenland’s first settlers arrived around 4,500 years ago, when small bands of Paleo-Eskimo peoples crossed from Arctic Canada onto an island of ice and extreme cold. The Saqqaq settled the southwest while the Independence I culture pushed into the far north, apparently unaware of each other. Their arrival marks one of humanity’s farthest reaches into the inhabitable world.
