The "People of the Ditch" refers to the ancient Native American culture known as the Hohokam, who lived in the present-day Southwestern United States, particularly in Arizona. They are recognized for their advanced irrigation systems, which allowed them to farm in the arid desert environment. Their settlements often featured large, complex canal systems that supported agriculture. This culture thrived from around 300 CE to 1500 CE, creating vibrant communities with distinctive pottery and trade networks. The decline of the Hohokam is attributed to various factors, including climate change and resource depletion, leading to their eventual disappearance from the region.
