A Skeleton Clue to Early American Ancestry

Caption: A broad view of Hoyo Negro, shot from the floor near the south edge, showing the immensity of the chamber and the complexity of the boulder-strewn bottom. One access tunnel can be seen near the ceiling at top left. This photo was taken by the "painting with light" method on a 30 second exposure.
