Weedon Island Culture

Weeden Island culture

The Weeden Island Culture is one of the many archaeological cultures that existed during the Late Woodland period of the North American Southeast. The name for this culture was derived from the Weedon Island site (despite the dissimilar spellings) in Old Tampa Bay in Pinellas County.


It is currently believed that the Weeden Island culture emerged from the Hopewell culture-based Swift Creek cultural tradition of northwest Florida during the Middle Woodland Period (ca. 200 - 500 CE) in the lower Chattahoochee-Apalachicola river drainage, persisting in some areas until the end of the Woodland period ca. 1200 CE. Weeden Island sites have been found from Mobile Bay to south of Tampa Bay, extending as far north as lower-central Georgia.

The current subsistence model for the Late Woodland Period of Florida shows that the Weeden Island peoples primarily occupied coastal areas and large river basins, exploiting local marine and terrestrial resources and utilizing upland interior regions almost exclusively for resource extraction, though some contest this. Although the multiple geographic variants of Weeden Island groups used slightly different subsistence strategies dictated by local environment (including small scale agriculture in some areas), a trend toward the semi-sedentary hunter-gatherer exploitation of hardwood hammock areas and coastal/riverine marine resources accurately characterizes Weeden Island subsistence activities in general.

The Weedon Island site was excavated by Smithsonian Institution archaeologist J. Walter Fewkes in 1923 and 1924. Recent archaeological work places the Weedon Island site outside the "heartland region" of the Weeden Island Culture, in northern and northwestern Florida. The site excavated on Weedon Island is now considered to be in the Manasota culture area, a "Weeden Island-related culture" in which typical Weeden Island pottery is found in mounds, but not in village middens.

Recent efforts have refined the Weeden Island culture concept so that the term "Weeden Island" includes several distinct regional manifestations which exhibited the same basic ceremonial complex (most likely associated with shared sociopolitical patterns), but that exhibited significant geographic variations. These include: the North peninsular Gulf Coast variant, found along the Gulf coast from Pasco County to the Aucilla River; the Cades Pond culture in north-central Florida; the McKeithen Weeden Island culture in northernmost inland Florida; the Manasota culture located within the central Peninsular Gulf Coast; the Northwest culture, extending from the Aucilla River through the Florida Panhandle to Mobile, Alabama; and more recently the Kolomoki culture, located in the lower Chattahoochee Valley.

Several attempts have been made to segregate Weeden Island components into chronological phases based on temporal changes in settlement patterns, artifact assemblage, and ceremonial activities, all of which recognize an inherent distinction between the material culture of earlier and later Weedon Island manifestations. It is most widely accepted that the Weeden Island culture be split into two time periods: the Weeden Island I Period (200 AD - 700 AD) and Weeden Island II Period (700 AD - 1200 AD). Some Weeden Island II cultures later developed into local variants of the Mississippian culture, collectively known as proto-Mississippian.

The Weeden Island culture was preceded by the Deptford culture (and the later Swift Creek and Santa Rosa-Swift Creek cultures in the panhandle). It was followed by the Alachua culture in the Cades Pond culture area, by the Suwannee Valley culture in the McKeithen culture area and by the Fort Walton culture in the Northwest area (the panhandle).

Several archaeologists including William Sears indicate "that there was a sharp dichotomy between sacred and the secular" artifacts (particularly ceramics) within the Weeden Island culture, though this pattern has not been observed west of the Aucilla River. (quote from Fagan, p.458).

"The social organization characteristic of ... Weeden Island sites appears to have lain somewhere between the basically egalitarian structure of Archaic hunter-gatherers and the chiefdoms characteristic of Mississippian society...over these centuries, the social, political, and ideological institutions of later Weedon Island agricultural communities and their contemporaries evolved into those associated with the Mississippian" (Fagan, p.460-461).

North peninsular Gulf coast region

The north peninsular Gulf coast variant of the Weeden Island culture existed along the Gulf of Mexico coast of Florida from the Aucilla River southward to what is now Pasco County. It also included such inland wetland areas as the Cove of the Withlacoochee (around Lake Tsala Apopka in Citrus County) and Gulf Hammock (in southern Levy County). This region has not received as much attention from archeologists as have other variants of the Weeden Island culture. While a number of sites have been surveyed, most of the mounds and shell middens in the area have been disturbed or destroyed by artifact hunters and "borrowing" for road-building material, and there have been no major excavations of sites in the region.

As in other Weeden Island areas, there is a difference between ceremonial/prestige pottery, found primarily in burial mounds, and the utilitarian pottery found in village sites and shell middens. The prevalence of undecorated pottery and the lack of major excavations means that the chronology of the Weeden Island culture in the north peninsular Gulf coast is poorly understood.

The Weeden Island culture was not uniform over the north peninsular Gulf coast. Ceramics related to the Swift Creek culture are found scattered at early sites throughout the area, but particularly so in Taylor County, the northernmost part of the region. Later sites in Taylor County show some influence from the Fort Walton culture. In Dixie County, to the south of Taylor County, later sites appear to have been influenced by the Alachua culture, which developed out of the Cades Pond variant of the Weeden Island culture. Later sites in the southern part of the region show influence from the Safety Harbor culture.

Primary habitation sites were concentrated along the coast, with smaller sites adjacent to inland waterways. The inhabitants left numerous shell middens, composed primarily of oyster shells, but also including clam, scallop, whelk and conch shells. Fish of various kinds were another important component of the diet. Sea turtles, tortoises, alligators and deer were also consumed. Horticulture was absent or a late introduction, although the inhabitants of the southern end of the region (Pasco and Hernando counties) were growing maize at the time of first European contact.
