[2] The social organization of the El Riego phase is characteristic of the Early Archaic period in Mesoamerica; hunter gatherer societies with established seasonal camps.
The hunter gatherer peoples traveled between the camps to follow the migration of the wild animals they hunted.
In the earlier part of the phase the people were most likely seasonal nomads, moving from small hunting camps and temporary villages.
[1] Through the archaeological excavations done on important sites such as Tecorral, Coxcatlán, Purron, and Abejas, material culture from the El Riego phase has been discovered and consists largely of stone tools, evidence of weaving through the discovery of blankets and baskets, and woodworking through the findings of dart shafts and animal traps.
[1] Numerous scraper planes and food-grinding stones dating to the El Riego phase were discovered at Coxcatlán Cave, as well as projectile points with greater form diversity than seen previously.
