PETERSBURG, Va. (AP) — The state Department of Mines, Minerals and Energy has received a $79,000 grant to begin work on a digital geologic map for Petersburg National Battlefield.

The mapping is made possible through a grant from the National Park Service.

DMME geologists will collect data to create the maps for the western part of the Petersburg Battlefield, the Five Forks Battlefield and surrounding areas.

The project is expected to help explain how geologic conditions played a role in the battle between the North and the South.

The project is expected to be completed in September 2016.
