Archaeologists have discovered the largest known Native American cave art images in North America on the walls of an Alabama cave, according to researchers in a paper published on Wednesday, May 4.
The large cave art is over 1,000 years old and may represent spirits of the underworld, the archaeologists said. They documented the cave with photogrammetry, a process in which thousands of photographs are taken and then used to build a 3D model.
Photographs of the cave art at an unspecified location in Alabama were taken by Alan Cressler. Images found on the cave walls include anthropomorphic figures and a serpent over three meters long, the researchers said. Credit: Alan Cressler via Storyful
