In the sequence of North American cultural stages first proposed by Gordon Willey and Philip Phillips in 1958, the Archaic stage was the second period of human occupation in the Americas, from around 8000 BC to 1000 BC although as its ending is defined by the adoption of sedentary farming, this date can vary significantly across the Americas.
It followed the Lithic stage and was superseded by the Formative stage.
The Archaic stage is characterised by subsistence economies supported through the exploitation of nuts, seeds and shellfish. Numerous local variations have been identified; in the Great Basin and western interior the period has been subdivided into Desert Archaic, Middle Archaic and Late Archaic whilst in south-western North America only a single Southwestern Archaic is recognised.
The site of Las Capas in southern Arizona has revealed irrigation canals dug in the Late Archaic indicating sophisticated methods of water control were being adopted. Terraced fields were also a feature of farming in Mexico's Northern Chihuahua province. Dating to around 1200BC. Hunting and gathering were still an important element in the lives of the inhabitants but they lived in identifiable permanent villages of pit houses associated with storage features and roasting pits.
Seeds stood in for maize as the main cultivated food source during the Middle and Late Archaic in eastern North America. Selective breeding of sunflower, sumpweed and chenopod plants created larger seeds which would have rendered the specimens unable to reproduce without human assistance.

Elsewhere, people were reliant on hunting. On the Great Plains, sites such as the later Head-Smashed-In in Alberta attest to the practice of driving bison over a cliff to kill them. The climate was colder and wetter at the time and killed bison could be preserved in the winter snows and dug out and thawed as needed. Summer species hunted included porcupine, deer and rabbit. Later in the Middle Archaic period the climate warmed and Bison numbers fell, leading humans to find new methods to survive. In the Rocky Mountains, people developed large nets to trap mountain goats and sheep and at Mustang Springs a well was dug to maintain a water supply. In the Later Archaic the weather cooled again and bison numbers recovered. Some groups built bison pounds in which to keep live animals until they were needed for slaughter. Teepees and medicine wheels appeared for the first time.
