The Thunderbird Archaeological District, near Limeton, Virginia, is archaeological district described as consisting of "three sites--Thunderbird Site, the Fifty Site, and the Fifty Bog--which provide a stratified cultural sequence spanning Paleo-Indian cultures through the end of Early Archaic times with scattered evidence of later occupation."〔 ==Thunderbird Site== This archaeological site, located in Warren County Virginia, near modern day Front Royal in the Shenandoah River Valley is a major site of the Paleoindian Clovis culture in Virginia. It was designated a National Historic Landmark in 1977 because it yielded dense archaeological remains as well as evidence for what is quite possibly the oldest structure in North America.〔 〔Note: A National Register of Historic Places Inventory-Nomination document (perhaps redacted to remove location information) should be available upon request from the National Park Service for this site, but it appears not to be available on-line from the (NPS Focus search site ).〕 The site is one of three which make up the Thunderbird archaeological complex which consists of 2,500 acres of sites spanning the prehistoric era. The major occupations at Thunderbird site are known to date to the Late Pleistocene-Early Holocene epochs and include Clovis and later projectile points forms, as well as an array of other tools and manufacturing debris.〔1. William M. Gardner (1983). Stop me if you’ve Heard This One Before: The Flint Run Paleo-Indian Complex Revisited. (Archaeology of Eastern North America) 1983. p.49-64.〕 Radiocarbon dates indicate some of the occupations date to 9900 BP (before present).〔2. David J. Meltzer (1988).
