Introduction

5 min

Read aloud

In a dry canyon in the American Southwest, Ancestral Puebloans built stone great houses with hundreds of rooms, long straight roads and calendars of light. Students explore Chaco Canyon and Mesa Verde, and why their people moved on rather than vanished.

By the end of the lesson, students can

  • Locate Chaco Canyon, Mesa Verde and the Hopi mesas on the map.
  • Describe a great house such as Pueblo Bonito and what it may have been used for.
  • Explain why Pueblo people say their ancestors moved, rather than disappeared, around 1300.

Explore the map

12 min

Project the map, or let students follow on their own devices. Each step opens the map at the right year and place.

AD 900

A name on the map

Open the map in 900 over the Four Corners region of the American Southwest. Find the label the map uses for this region. Many Pueblo people prefer the term "Ancestral Puebloans". Why might a name matter?

AD 1100

Chaco Canyon

Jump to 1100 and zoom in on Chaco Canyon. Pueblo Bonito, its largest great house, had more than 600 rooms and rose four storeys high. Look at the land around it: where would water and food come from?

AD 1280

Cliff houses

Move north to Mesa Verde in 1280. Families built homes in the cliffs here, then left by about 1300 during a long drought. Zoom out and find the Rio Grande to the south-east: many of them moved there.

Class discussion

14 min

Pick two or three. They run from what happened to why it mattered.

  1. Chaco Canyon is dry and has a short growing season. Why might people still build a great centre there?
  2. Straight roads up to 9 m wide lead out from Chaco. What could they have been for?
  3. Cacao and macaw feathers from Mesoamerica were found at Pueblo Bonito. What does that tell us about trade?
  4. Tree rings show a great drought from 1276 to 1299. How can tree rings record the weather of the past?
  5. Pueblo people say their ancestors moved on and live on in their descendants. Why do they object to the phrase "mysterious disappearance"?

Game round

9 min

Play one round of Rule History as Genghis Khan, who conquered much of Asia in the decades when families at Mesa Verde built homes in the cliffs. Afterwards, compare: Genghis Khan moved armies to gain land, while Ancestral Puebloan families moved to survive a drought. What makes a move like that a wise choice?
