The problem with Las Haldas is that it should not exist. A ceremonial complex of forty hectares, sprawling mounds and plazas and a great U-shaped platform, built during a period when the textbooks said civilization required grain surpluses to feed cities. But Las Haldas had no grain. The ground around it is bone dry, receiving less than an inch of rain a year. There is no river, no spring, no viable farmland for kilometers.
