Sourcing of an Unidentified Chert from Western Wisconsin Paleo-Indian Assemblages
نویسنده
چکیده
A number of Paleo-Indian artifacts found in Western Wisconsin lithic assemblages were observed to be made of an unidentified olive green colored chert. A macroscopic examination of these artifacts, and comparison with known possible sources suggested that the material might be Silurian Chert Type II from the Door Pennisula in eastern Wisconsin. Attributed analysis and comparison with lithic debris found at sites in that area supports this hypothesis.

Siliceous sedimentary rocks of Tertiary age were recovered at three of the nine sites drilled during Leg 31 (Table 1). Only relatively small amounts of lithified material were retrieved, but these rocks are particularly interesting because they include three distinct types of siliceous rock and because each type occurs with a distinct sediment lithology. The kinds of rocks sampled are (with lit...

BACKGROUND It is widely accepted that the ancestors of Native Americans arrived in the New World via Beringia approximately 10 to 30 thousand years ago (kya). However, the arrival time(s), number of expansion events, and migration routes into the Western Hemisphere remain controversial because linguistic, archaeological, and genetic evidence have not yet provided coherent answers. Notably, most...

The Upper Kickapoo River Archaeological District contains over 500 archaeological sites. Spatial statistics and site selection factors were explored for 405 open archaeological sites. Nearest Neighbor Index and Ripley’s K-Function analyses show that the sites have a clustering pattern. Hot spot analyses reveal concentrations near a few stream confluences. Topographic variables of the site locat...
