The MDEQ produces Natchez Trace geological maps – Picayune Item


(JACKSON, Mississippi) – The office of geology of the Mississippi Department of Environmental Quality (MDEQ) recently released five geological maps produced for the National Park Service regarding areas along the Natchez Trace Parkway. The 7.5 min. Geological quadrangles for the Ridgeland, Pocahontas, Clinton, Raymond and Widows Creek areas in Claiborne County were published in December 2021. This work was carried out as part of an ongoing three-state cooperative project coordinated and funded by the National Park Service to explore and map for the first time the complete geology of the Natchez Trace Parkway corridor.

The maps include surface geological interpretations, cartographic descriptions, and supporting photographs and figures illustrating areas of interest. They also provide information on geology, geography, geomorphology, stratigraphy, natural and cultural history, paleontology, geoarchaeology, as well as significant geohazards including the Yazoo Clay outcrop belt and distribution. loess. In addition, the maps are useful for activities such as economic development as well as environmental, municipal and conservation planning.

The maps are available to the public for free download at The MDEQ website here. Mapping will continue to be done over the next several years, resulting in a complete geological interpretation for the entire Natchez Trace promenade.
