“Battlefield Rocks; The Geology of an Indelible Landscape” LBG Britt Isenberg

Traditionally, visitors to the battlefield at Gettysburg have rightfully focused their interests on the events of 1863 or the Eisenhower farmstead. However, that very battlefield landscape holds a uniquely dynamic story that pushes the historical record hundreds of millions of years before the battle occurred. This program will consider Gettysburg’s geological landscape and how it influenced the events of 1863 but also shine a light on the incredible geologic specimens brought to the battlefield by veterans during the commemorative era. We’ll visit Bryozoan fossils, a massive chunk of puddingstone, Jurassic era deposits, and spy the evidence of mountain-building and rifting events that will leave our understanding of volcanic activity shivering. Join us on this experiential odyssey that brings the story of our planet to the forefront of our human
experience.
