SURFICIAL MAPPING OF THE VICKSBURG NATIONAL MILITARY PARK

This research has been conducted in Vicksburg Mississippi within the Vicksburg National Military Park and surrounding areas, to produce four 7.5 minute geologic maps. Four quadrangles intersect the park: Redwood, Long Lake, Vicksburg East, and Vicksburg West. These are the four quadrangles of interest for this project. The park service has prioritized the delineation of geologic resources in the Military Park to be achieved throughout geologic mapping. The resulting maps contribute to improve historical understanding, as well as engineering purposes such as mining and mitigation of slope failure. This project provides new geologic mapping to Vicksburg National Military Park by updating and integrating existing floodplain maps with new bedrock and surficial mapping in the four 7.5 minute quadrangles in and around the Vicksburg National Military Park. Only the floodplain portion of Vicksburg had been mapped. The remainder of data utilized in this investigation have come from original field mapping. New geologic maps have been produced for the areas outside of the floodplain. Primary sources that have been consulted to create the base map were collected by the National Park Services (NPS), Mississippi Department of Environmental Quality (MDEQ), Mississippi Department of Transportation (MDOT), and The Army Corps of Engineers. The National Park Service has provided all relevant NPS Vicksburg data sets and other associated data that may be important to geologic mapping and data interpretation. Such data sets include, but limited to, park boundaries, park infrastructure/facilities, historical data, and more. All relevant LIDAR imagery has also been provided as well as aerial imagery

The revised floodplain maps and new geologic maps will then be integrated in a GIS project. The resulting final maps will be delivered to the National Park Service Geologic Resources Inventory where they will be converted into the NPS Geologic Map Data Model and distributed to Vicksburg staff as a portion of the National Park Service Geologic Resources Inventory. Maps will then be published by the state of Mississippi Department of Environmental Quality.
