Oaxaca
The valley around the city, creek by creek
▶ Play it onlineOaxaca city sits in a high valley where three valleys meet, beside the Atoyac, the river that becomes the Río Verde. This plate is the land around it, from the hills of Etla in the north down to the city, cut into the catchments of the creeks that run into the river. Five levels above it this was a sliver of the Pacific slope of North America; here the city and the mountains around it are the whole plate.
What a child works out
- A city grows where valleys meet and water runs.
- Every creek around a town has its own small territory.
- The same place looks completely different at every scale.

A piece of each of these is the subject of the next one. Each plate is redrawn at its own scale, so it is a real map at every level rather than an enlargement of the one above.
