known in Mexico as "Gran Chichimeca" and in United States is called American Southwest. Sites of culture are located in the State of Chihuahua; Paquimé was the head and commercial center of the region. The first settlements in this culture are dated 1000 BCE, since the late archaic); its apogee occurred between 1261 and 1300 CE, and disappeared in 1450 CE. The difficult nature of this area shaped the distinctive traits of its inhabitants; who developed from nomadic hunter-gatherers to sedentary, farmed the land and animals. Sites of the culture are found from the Pacific Ocean coast to the Sierra Madre Occidental, passing through all kinds of ecological and climate environment. El Sitio The cave lies at the foot of a vertical cliff and from the entrance has an excellent view. The cave has two levels, in both are numerous archaeological remains. On the upper level there are more than 10 very well preserved adobe rooms. The first level is only a rocky shelter; to reach the second level, a makeshift ladder is used, then follow up a ramp between stones to the second level. This room has a wide window from which a beautiful view of the Canyon is seen. The cave is not very wide, but it is an excellent shelter. At the precipice edge, next to the window, are the remains of an old adobe room. On the floor of this room was the partly buried mummy was found. At the entrance of another adobe house, are remains of another mummy, badly damaged by vandals. It contained much of the remains and tissue and the Petate bedroll used to wrap the burial. For a couple of years Ciudad Juárez Autonomous University scholars denounced to INAH their finding, but to date there has been no response. Rooms In both levels are archeological remains on both sides. At the top level, is a complex of small houses made of mud and grass that had been built in the shelter of the cave. These valuable remains of the Paquimé culture, part of the so-called Oasisamerica region, are at serious risk, given that antiques buyers are eager to get these pieces, especially in the United States; and must sadly note, the Government abandonment, also responsible for the situation. The mummy The mummified body of an adult individual was found, surrounded by offerings such as ceramics, stone utensils, stems and corn cobs.
