Cutzamala
Cutzamala lies in the far northwest of Guerrero, where the state meets Michoacán and the Cutzamala River runs down through deep valleys toward the Balsas. Cuitlatec communities farmed the valley bottoms and the slopes above them, growing maize and fruit, while Purépecha-speaking neighbours to the north traded with them across the border of the hills. The valley was a route between the Balsas lowlands and the highland towns, and under the Mexica empire its villages sent tribute of cotton and cloth to the lords of the region.
