Antonio de Espejo
In February 1583, Espejo arrived at the territory of the Piros, the most southerly of the Pueblo villagers. From there the Spanish continued up the Rio Grande. Espejo described the Pueblo villages as "clean and tidy". The houses were multi-storied and made of adode bricks. "They make very fine tortillas," Espejo commented, and the Pueblos also served the Spanish turkeys, beans, corns, and pumpkins. The people "did not seem to be bellicose". The southernmost Pueblos had only clubs for weapons plus a few "poor Turkish bows and poorer arrows". Further north, the Indians were better armed and more aggressive. Some of the Pueblo towns were large, Espejo described Zia as having 1,000 houses and 4,000 men and boys. In their farming, the Pueblos used irrigation "with canals and dams, built as if by Spaniards". The only Spanish influence that Espejo noted among the Pueblos was their desire for iron. They would steal any iron article they could find.
Lomas
In many locations the lomas were over-exploited for agriculture and grazing. One example is that, in prehistoric times, north of Ilo, Peru, far from any other source of water, four lomas-fed springs permitted about of irrigated agriculture plus grazing for llamas and alpacas. Hundreds of people of the Chiribaya culture benefited from this unlikely agriculture in a rainless land. Later, during the 17th century, Spanish colonists pastured 200 mules in these lomas. As late as 1951, a few tara trees still lived although the lomas were by then nearly devoid of all vegetation and population.
