Cueva de la Olla (cave of the pot) is an archaeological site located in the northwest of the Chihuahua State, some 47 km southwest of Nuevo Casas Grandes near the Ignacio Zaragoza Ejido. To get there, take the road from Casas Grandes to Colonia Juarez, continue to the Ignacio Zaragoza ejido (dirt road with one way sections). At the exit, go forward two kilometers to the Casa Blanca Ranch, the site is one kilometer from the ranch, the site is perhaps the oldest in Chihuahua and Mexico, the Golondrina Cave is only 400 meters from the site. The Site is located within the natural shelter of the cave. This site received its name because it has a rounded shape structure, shaped like a pot (or olla, in Spanish). It is a Cuexcomate, or large barn type facility, with a shape that resembles a large vase. Similar granaries were located in scattered caves sites of the Sierra Madre Occidental. One of the particularities of the Valle de las Cuevas (valley of the caves) is the presence of a site where a sequence of very long human occupation has been detected. Human groups that lived in the region used a maize ancestor variety, dating approximately 5500 BCE. Due to the cold winter, there was the need to store food, hence they built the barn which can still be seen, although very deteriorated. The Cultures Human groups of hunter-gatherers arrive in the region from the north, probably Mogollon, Anasazi or Hohokam, following the Sierra Madre Occidental; used plants, took advantage of smaller animal species, as turkeys; occupied the mountains and gradually dispersed in rivers, developing the Paquimé culture or "Casas Grandes", whose first settlers were collectors in the process of learning sedentary traits. Cueva de la Olla belongs to an earlier occupation stage called "Perros Bravos" (Fierce Dogs), from 950 to 1060 CE. Mogollon ( or ) culture evidences have been found, simple ceramic fragments and other more scarce luxury type materials, characteristic of the Paquime culture. The Site constructors probably were villagers who in addition to intensively exploit the environment, as can be seen in the premises vestiges, cultivated corn, squash, and beans, therefore they established a community use system. It is presumed that the group living in the Cueva de la Olla was a group of at least 30 individuals, that probably worked the flat land areas of the region, adequate
