This site is proposed as a reference to characterize the known lithic materials of Mississippi. In archaeology, lithics are stone artifacts that have been purposefully modified, or worked, by human hands. In this science, where the anthropological theory of pre-historic cultures is pondered and debated largely on the examination of worked stone objects, an understanding of the presence and source of naturally occurring stones or native materials throughout the local geology is an important piece of information when investigating pre-historic, aboriginal sites. Understanding the source of these native materials provides the archaeologist insight into the relationship of past cultures with their available geological resources and how that relationship may have evolved over time.

(JACKSON, Miss.) -- Starting in late February and running through early March 2018, the United States Geological Survey (USGS) will use a specialized instrument towed beneath a low-flying helicopter to collect data about the Mississippi River Valley Alluvial Aquifer in an area just north of Greenwood. The instrument is contained in a 30-foot long torpedo-shaped tube that will be suspended 100 feet below the helicopter, which will fly at an altitude of 200 feet. The data collected will allow scientists to better understand the properties of geologic layers beneath the land surface. Details of this data collection project are explained further in the attached USGS fact sheet. Additional information can be found at the following website:
