Chaco Boreal

Chaco Boreal is a traditional method of ice preservation and storage used by indigenous peoples in northern Mexico. It involves creating a natural ice cellar by digging into cold, shaded areas or ice-rich ground, often with insulated walls, to keep ice and perishable goods cool during hot months. This technique relies on the natural environment to maintain low temperatures without electrical refrigeration, preserving food sustainably. Chaco Boreal exemplifies ancient ingenuity in utilizing local terrain and climate for food storage, showcasing traditional knowledge adaptable for sustainable practices today.
