How did the Anasazi prehistoric people (also called the Ancestral Pueblo) harvest water in the arid regions they occupied in northern Arizona?
Cobble Mulch = Stones provide shade, trap moisture,
prevent evaporation, and prevent runoff of rain water.
Prevents water from flowing too quickly
Allows better permeation of hard soils
Helps in capture of surface water due to rains
We live in a diverse planet with a variety of ecosystems and environments that challenge how people survive. How humans innovatively harvest water is what marks us as the intelligent, creative, and determined people we are.
Used in other regions of North America, as well as South America
