The Dynamics of Chacoan Social and Spatial Networks, AD 800-1200
Project Overview
This project investigates how communities across the Chaco World were connected and how those relationships changed over time. Using archaeological data and social network analysis, it explores the rise of Chaco Canyon, regional interaction, migration, and the development of social inequality in the ancient Southwest.

Project Details
How do large regional communities emerge, maintain connections across great distances, and respond to environmental and social change? This project investigates these questions through the study of the Chaco World, a network of communities centered on Chaco Canyon in northwestern New Mexico between A.D. 800 and 1200. By examining patterns in architecture, ceramics, stone tools, and settlement locations, the project explores how communities were connected across a vast region and how those connections changed through time.
The research combines archaeological data, social network analysis, and geographic information systems to examine the relationships among great houses, great kivas, and surrounding communities throughout the Chaco World. By tracing shifts in regional interaction, migration, and settlement organization, the project investigates how social networks contributed to the rise of Chaco Canyon as a major center and how changing environmental conditions influenced the reorganization of communities across the Southwest. The resulting database and analytical tools provide new insights into the development of social inequality, regional integration, and long-term social change in non-state societies.
