A thousand or more years ago, natives inhabited the lower elevations around the San Francisco Peaks of Northern Arizona. In an area so dry it would seem impossible to live, they built pueblos, harvested rainwater, grew crops, hunted game and raised families. Today the remnants of their villages dot the landscape along with other artifacts such as this obsidian projectile point from the Sinaguan era; about 500AD to 1450AD. Although commonly called an arrowhead, the point was probably not attached to an arrow or shot from a bow, a weapon not thought to be used by the Sinagua. More likely it was affixed to the tip of a spear and thrown to strike and kill game animals. It is unlawful to remove artifacts, such as this point, from a native site. They may be examined but must be returned to their original location. This projectile point was photographed at Sandy Seep in the Coconino National Forest near Flagstaff, Arizona, USA.
