Colonial Era Firearm Bullet Performance: A Live Fire Experimental Study for Archaeological Interpretation

The results of this live fire experiment with Colonial and Revolutionary War firearms are a beginning for the investigation of late pre-modern gun use. To determine what happens when large-caliber lead balls were used in combat or hunting we observed impacts of experimentally fired balls into ballistic gelatin, an accepted tissue simulant with end coverings to simulate clothing of the era, and into a sand backstop. We also used a wooden palisade made up of dry loblolly pine, green loblolly pine, live oak, and maple palings to obtain bullet impact information. Projectile deformation associated with varied ranges were catalogued. The results of these experiments will permit archaeologists to better interpret recovered projectiles.

Stone Mountain Petroglyphs Path

The Petroglyphs Path project’s mission is to provide a comprehensive, digital archive of the historic petroglyphs on the Summit Trail of Stone Mountain. Stone Mountain is located approximately 16 miles East of Atlanta, Georgia. Petroglyphs recorded on the Summit trail date from the 1860’s to the present. A total of 652 petroglyphs were recorded during the survey and are presented here in an interactive webmap.
