The Sage Wall in Montana is an incredible mystery—natural or man-made? A simple, non-invasive paleomagnetic test could reveal the answer. By analyzing the magnetic orientation in its granite blocks, scientists can determine if they cooled in place (natural) or were moved and placed (human-made). If the magnetic signatures vary, it suggests human construction; if they align consistently, it points to natural formation. This test could finally solve the debate with real, scientific evidence
