Archaic Southwest

The Archaic Southwest was the culture of the North American Southwest between 6500 BC and 200 AD (approximately).
The Paleo-Indian tradition before that dates from 10,500 BC to 7500 BC. The Southwestern United States during the Archaic time frame can be identified or defined culturally in two separate ways:
As the climate warmed at the end of the Ice Age, mammoths and large animals such as horses and camels began to disappear. Hunter/gatherers gradually adapted to these changes, supplementing their diet with a variety of plant foods and smaller game. The Archaic people used nets and the atlatl to hunt water fowl, ducks, small animals and antelope. Hunting was especially important in winter and spring months when plant foods were scarce.
The Archaic time frame is defined culturally as a transition from a hunting/gathering lifestyle to one involving agriculture and permanent, if only seasonally occupied, settlements. In the Southwest, the Archaic is generally dated from 8000 years ago to approximately 1800 to 2000 years ago. During this time the people of the southwest developed a variety of subsistence strategies, all using their own specific techniques. The nutritive value of weed and grass seeds was discovered and flat rocks were used to grind flour to produce gruels and breads. This use of grinding slabs in about 7500 BCE marks the beginning of the Archaic tradition. Small bands of people traveled throughout the area, gathering plants such as cactus fruits, mesquite beans, acorns, and pine nuts. Archaic people established camps at collection points, and returned to these places year after year. They lived primarily in the open, but probably also built temporary shelters. Known artifacts include nets woven with plant fibers and rabbit skin, woven sandals, gaming sticks, and animal figures made from split-twigs.
Late in the Archaic Period, corn, probably introduced into the region from central Mexico, was planted near camps with permanent water access. After planting, it appears the hunter-gatherers moved on to other territory to gather wild foods, and returned later in the season to harvest the ripened grain. Archaeologist Wirt H. Wills asserts that corn was originally introduced into the Southwest when the region's climate was somewhat wetter and cooler. Distinct types of corn have been identified in the more well-watered highlands and the desert areas, which may imply local mutation or successive introduction of differing species. Emerging domesticated crops also included beans and squash.
About 3,500 years ago, climate change led to changing patterns in water sources. The population of Desert Archaic people appears to have dramatically decreased. However, family-based groups took shelter in caves and rock overhangs within canyon walls, many facing south to capitalize on warmth from the sun during winter. Occasionally, these people lived in small semisedentary hamlets or pueblos in open areas. Evidence of significant occupation has been found in the northern part of the Southwest range, from Utah to Colorado, especially in the vicinity of modern Durango, Colorado.
Archaic cultural traditions include:
Many contemporary cultural traditions exist within the southwest, but there are four major ones.
