Obsidian Point

The IDEA Lab at Northern Arizona University uses noninvasive coating techniques to photograph delicate artifacts.  These techniques help to document these rare objects and to reveal their surface details. This photograph is a close-up of an obsidian projectile point, among the oldest known human-made objects in Arizona. Northern Arizona University Professor of Anthropology Dr. Chris Downum is using this and other stunning, close-up images on an interactive website called the American Southwest Virtual Museum.  Photo: IDEA Lab
