Smithsonian shares how 3D scanning revealed cave art made by Native Americans in northern Alabama.
The exact location of the 19th Unnamed Cave, somewhere on private land in northern Alabama, is a closely guarded secret. What’s inside is too precious to risk destruction. An 80-foot-wide, east-facing mouth leads to a long tunnel where the ceiling and floor draw closer and closer together. You can’t quite stand up, but you don’t need to crawl, says photographer Stephen Alvarez, founder of the Ancient Art Archive and co-author of a new paper on the cave. The floors are uneven. Big pools of water are scattered everywhere. When you’re a long way from the entrance but can still see some daylight, that’s where the artwork begins.
