Abstract
A new hydration rate is presented for the Government Mountain-Sitgreaves Peak obsidian source in Arizona. It is based on an analysis of hydration measurements from a series of independently dated obsidian artifacts from that source. Since obsidian obtained from Government Mountain-Sitgreaves Peak was widely traded in the prehistoric Southwest, the new hydration rate should provide archaeologists working in many parts of the Southwest with a reliable and inexpensive absolute dating technique.Keywords
