The Anasazi formed the Chaco Canyon as a spiritual and trading center connecting the contrasting ecological zones of the San Juan Basin, and upper highland areas. The patterns shifting from in hotter years the upland does well in the growing season, and the basin does well in cooler years. The trade started here was developed to facilitate risk between oscillating regions. The Tepary bean is domesticated being the most drought tolerant legume it can survive in regions with less than 16 inches a year. They also facilitated the growth of prickly pear cactus fruit, mesquite bean, sunflower and wild grasses for their seeds.

Then from 750 to 850 this pattern of oscillation between regions becomes more solidified even within the basins northwest and southeastern regions.
