Archaic period in the Americas in the context of "Woodland period"

Many pre-Columbian cultures in North America were collectively termed "Mound Builders", but the term has no formal meaning. It does not refer to specific people or archaeological culture but refers to the characteristic mound earthworks that indigenous peoples erected for an extended period of more than 5,000 years. The "Mound Builder" cultures span the period of roughly 3500 BCE (the construction of Watson Brake) to the 16th century CE, including the Archaic period (Horr's Island), Woodland period (Caloosahatchee, Adena and Hopewell cultures), and Mississippian period. Geographically, the cultures were present in the region of the Great Lakes, the Ohio River Valley, Florida, and the Mississippi River Valley and its tributary waters. Outlying mounds exist in South Carolina at Santee and in North Carolina at Town Creek.

The first mound building was an early marker of political and social complexity among the cultures in the eastern part of what is now the United States. Watson Brake in Louisiana, constructed about 3500 BCE during the Middle Archaic period, is the oldest known and dated mound complex in North America. It is one of 11 mound complexes from this period found in the Lower Mississippi Valley.These cultures generally had developed hierarchical societies that had an elite. These commanded hundreds or even thousands of workers to dig up tons of earth with the hand tools available, move the soil long distances, and finally, workers to create the shape with layers of soil as directed by the builders. However early mounds found in Louisiana preceded such cultures and were products of hunter-gatherer cultures.

Agriculture in Mesoamerica dates to the Archaic period of Mesoamerican chronology (8000–2000 BC). At the beginning of the Archaic period, the Early Hunters of the late Pleistocene era (50,000–10,000 BC) led nomadic lifestyles, relying on hunting and gathering for sustenance. However, the nomadic lifestyle that dominated the late Pleistocene and the early Archaic slowly transitioned into a more sedentary lifestyle as the hunter-gatherer micro-bands in the region began to cultivate wild plants. The cultivation of these plants provided security to the Mesoamericans, allowing them to increase surplus of "starvation foods" near seasonal camps; this surplus could be utilized when hunting was bad, during times of drought, and when resources were low. The cultivation of plants could have been started purposefully, or by accident. The former could have been done by bringing a wild plant closer to a camp site, or to a frequented area, so it was easier to access and collect. The latter could have happened as certain plant seeds were eaten and not fully digested, causing these plants to grow wherever human habitation would take them.

As the Archaic period progressed, cultivation of plant foods became increasingly important to the people of Mesoamerica. The reliability of cultivated plants allowed hunting and gathering micro-bands to establish permanent settlements and to increase in size. These larger settlements required a greater quantity of food, consequently leading to an even greater reliance on domesticated crops. Eventually, the Mesoamerican people established a sedentary lifestyle based on plant domestication and cultivation, supplemented with small game hunting. This sedentary lifestyle reliant on agriculture allowed permanent settlements to grow into villages and provided the opportunity for division of labor and social stratification.

Manitoulin Island (/ˌmænəˈtuːlɪn/ MAN-ə-TOO-lin) is an island in Lake Huron, located within the borders of the Canadian province of Ontario, in the bioregion known as Laurentia. With an area of 2,766 km (1,068 sq mi), it is the largest lake island in the world, large enough that it has over 100 lakes itself. In addition to the historic Anishinaabe and European settlement of the island, archaeological discoveries at Sheguiandah have demonstrated Paleo-Indian and Archaic cultures dating from 10,000 BC to 2,000 BC.

The current name of the island is the English version, via French, of the Ottawa or Ojibwe name Manidoowaaling (ᒪᓂᑝᐙᓕᓐᒃ), which means "cave of the spirit". It was named for an underwater cave where a powerful spirit is said to live. By the 19th century, the Odawa "l" was pronounced as "n". The same word with a newer pronunciation is used for the town Manitowaning (19th-century Odawa "Manidoowaaning"), which is located on Manitoulin Island near the underwater cave where legend has it that the spirit dwells. The modern Odawa name for Manitoulin Island is Mnidoo Mnising, meaning "Spirit Island".

Horr's Island is a significant Archaic period archaeological site located on an island in Southwest Florida formerly known as Horr's Island. Horr's Island (now called Key Marco, not to be confused with the archaeological site Key Marco) is on the south side of Marco Island in Collier County, Florida. The site includes four mounds and a shell ring. It has one of the oldest known mound burials in the eastern United States, dating to about 3400 radiocarbon years Before Present (BP). One of the mounds has been dated to as early as 6700 BP. It was the largest known community in the southeastern United States to have been permanently occupied during the Archaic period (8000 BCE-1000 BCE).

The island is named for Capt. John Foley Horr, who raised pineapples on the island in the late 19th century. The Capt. John Foley Horr House was listed on the U.S. National Register of Historic Places on October 8, 1997. In the late 1980s, a development company planned to build a bridge to Horr's Island and develop it. In response to state law requiring an archaeological assessment of the island before it could be developed, the development company funded a research project. The research team carried out excavations for three months.
