During the Archaic period, Indigenous peoples in the Americas transitioned from the highly nomadic lifestyles of their Paleo-Indian predecessors to more sedentary patterns, often establishing seasonal settlements. This shift was primarily driven by changes in the environment and economic strategies.12

As the climate warmed and dried, megafauna became scarce, prompting groups to diversify their subsistence strategies. Rather than roaming across the entire landscape, they began to rely on a broader, more reliable array of food resources, including smaller game, fish, shellfish, and various plant foods like seeds, nuts, and tubers.132

Because these food sources were often tied to specific locations and seasonal availability, groups began to congregate in larger numbers and build seasonal residences, frequently along waterways. This more stable subsistence base allowed for increased social complexity and the development of new technologies, such as basketry and grinding stones, which further facilitated the collection and storage of these diverse food resources. By foraging from these seasonal camps, Archaic peoples were able to adapt effectively to their local environments.123
