Huamango is an early Postclassical (Toltec period) archaeological site located about 4 kilometers northwest of the modern city of Acambay in the State of Mexico. The archaeological area is on the San Miguel plateau, in the vicinity of the Peña Picuda hill, at an approximate altitude of 2,850 (meters above sea level), it is rich in legends, stories and ancestral traditions. The site has vestiges of a city inhabited by the Otomi culture, which dominated the Acambay Valley, strategically located by the apparent defensive needs in the dispute over control of territory and trade routes. Huamango was most likely a major political capital in the area immediately north of the Toluca Valley during Early Postclassical times, perhaps subsidiary in some way to the Toltec polity centered at Tula to the northeast. The site is maintained by the Instituto Mexiquense de Cultura, a branch of the State of Mexico. It is easy to reach by car, about an hour's drive north of Toluca, and a few km north-west of Acambay. Prehistory In prehistoric State of Mexico, the Tepexpan Man is an important finding for Mexican and foreign anthropologists; it is an important key to understand what the Valley of Mexico area was like, 5000 years ago, as well as helping establish the occupation chronology of the region. Some scholars attribute an age of 11 thousand years, others 8 thousand, and some have suggested 5 thousand years old. This individual, originally identified as a male, recent research confirm a female identity, although this is still subject of discussion. Sacrum bone found in Tequixquiac is considered a work of prehistoric art. The town was inhabited in 35,000 BCE by primitive men who had crossed the Bering Strait from Asia. These people were nomadic, hunting large animals such as mammoths and gathering fruits as evidenced by archaeological evidence found at the site. One of the most salient discoveries of primitive art in America was found in here, called the Tequixquiac Bone, which had no known purpose, but reflected the ideological sense of the artist who carved the piece of bone from a camelid around 22,000 years BCE. The first native settlers of Tequixquiac were the Aztecs and Otomi, who decided to settle there permanently for the abundance of rivers and springs. They were engaged mainly in agriculture and the breeding of domestic animals. The earliest evidence of human habitation in current territory of the
