The siege of Petersburg and Richmond during the American Civil War in 1864–1865 provides a stellar example of how geology can affect military operations and thus the course of history. During the Union drive to take the Confederate capital, they used Virginia’s broad tidal rivers on the Atlantic Coastal Plain as supply lines for their huge army. During the siege, both sides took advantage of the unconsolidated Cenozoic sediments of the Coastal Plain to create a new style of combat—trench warfare—which would be taken to horrifying extremes in World War I. This trip visits seven sites of both historic and geological significance in the Petersburg area.

From the Blue Ridge to the Beach: Geological Field Excursions across Virginia
This volume includes seven field guides that explore the diverse geology of Virginia from its Appalachian highlands to the Atlantic shore. The guides cover an array of topics ranging from cave and karst development in the Valley and Ridge to the exceptional fossil localities at the Carmel Church Quarry and the cliffs near Stratford Hall to Precambrian rocks in the Blue Ridge Mountains. Three guides focus on the Paleozoic to Proterozoic tectonic history of the Blue Ridge and Piedmont provinces, two guides discuss the stratigraphy and fossil assemblages preserved in Cenozoic deposits on the Atlantic Coastal Plain, one guide examines Paleozoic stratigraphy and cave formation in western Virginia, and the final guide explores the relationship between the geology of the Fall Zone and the Civil War during the Petersburg Campaign in 1864–1865.
