Review Questions

• How did environmental factors influence the rise and fall of the Chaco Canyon civilization?
  • Environmental factors such as water availability and climate played a crucial role in the development of Chaco Canyon. The presence of water sources allowed for agriculture, which supported population growth and led to the construction of large communal buildings. However, prolonged droughts in the late 12th century severely impacted agriculture, contributing to resource depletion and social stress, ultimately leading to the decline of this complex society.
• Discuss the architectural significance of Chaco Canyon's great houses and their role in societal organization.
  • The great houses of Chaco Canyon are notable for their size, sophistication, and construction techniques. These monumental structures served not just as residences but also as centers for political and ceremonial activities. The architectural layout reflects a highly organized society capable of mobilizing labor and resources, indicating complex social hierarchies and community cooperation among the Ancestral Puebloans.
• Evaluate the impact of trade networks established by the Chaco Canyon civilization on its regional interactions and eventual collapse.
  • Trade networks were vital to Chaco Canyon's prosperity, allowing for the exchange of goods like pottery, turquoise, and macaws from distant regions. These connections fostered cultural interactions but also increased reliance on external resources. As environmental conditions worsened, these dependencies became critical vulnerabilities. The disruption of trade routes due to drought and resource scarcity likely accelerated societal collapse as communities faced increasing challenges without their usual support systems.
