Six earth-and-rock mounds rise out of the windswept desert of the SupeValley near the coast of Peru. Dunelike and immense, they appear to be nature’s handiwork, forlorn outposts in an arid region squeezed between the Pacific Ocean and the folds of the Andean Cordillera. But looks deceive. These are human-made pyramids, and compelling new evidence indicates they are the remains of a city that flourished nearly 5,000 years ago. If true, it would be the oldest urban center in the Americas and among the most ancient in all the world.
From This Story
Research developed by Peruvian archaeologist Ruth Shady Solís of San Marcos University suggests that Caral, as the 150-acre complex of pyramids, plazas and residential buildings is known, was a thriving metropolis as Egypt’s great pyramids were being built. The energetic archaeologist believes that Caral may also answer nagging questions about the long-mysterious origins of the Inca, the civilization that once stretched from modern-day Ecuador to central Chile and gave rise to such cities as Cuzco and Machu Picchu. Caral may even hold a key to the origins of civilizations everywhere.
Though discovered in 1905, Caral first drew little attention, largely because archaeologists believed the complex structures were fairly recent. But the monumental scale of the pyramids had long tantalized Shady. “When I first arrived in the valley in 1994, I was overwhelmed,” she says. “This place is somewhere between the seat of the gods and the home of man.” She began excavations two years later, braving primitive conditions on a tight budget. Fourteen miles from the coast and 120 miles north of Peru’s capital city of Lima, Caral lies in a desert region that lacks paved roads, electricity and public water. Shady, who enlisted 25 Peruvian soldiers to help with the excavations, often used her own money to advance the work.
For two months she and her crew searched for the broken remains of pots and containers, called potsherds, that most such sites contain. Not finding any only made her more excited; it meant Caral could be what archaeologists term pre-ceramic, or existing before the advent of pot-firing technology in the area. Shady eventually concluded that Caral predated Olmec settlements to the north by 1,000 years. But colleagues remained skeptical. She needed proof.
In 1996, Shady’s team began the mammoth task of excavating Pirámide Mayor, the largest of the pyramids. After carefully clearing away several millennia’s worth of rubble and sand, they unearthed staircases, circular walls covered with remnants of colored plaster, and squared brickwork. Finally, in the foundation, they found the preserved remains of reeds woven into bags, known as shicras. The original workers, she surmised, must have filled these bags with stones from a hillside quarry a mile away and laid them atop one another inside retaining walls, gradually giving rise to the city of Caral’s immense structures.
