Photos by Richard Barnes @richardbarnes | I did a story illustrating how laser archaeology works, and one of the preservation sites was Mount Rushmore National Memorial. The team I worked with from CyArk, based in the U.S., collaborated with Historic Scotland and the Glasgow School of Art. The laser archeologists repelled down every one of the granite faces, using laser technology to map within an accuracy of 3 millimeters. The mapping is used to create 3D models, so that historic monuments may be restored in case of erosion, natural disasters, war, or terrorism. Thanks to related technology, art historians and architects will be able to reconstruct Notre Dame, recently ravaged by fire. Mount Rushmore depicts four U.S. presidents: Washington, Jefferson, Roosevelt, and Lincoln. It was constructed over a period of 14 years in the Black Hills of South Dakota. #richardbarnes #laserarchaeology #mountrushmore #blackhills #southdakota
