Popis:	For over a decade and a half the locality of “AZ Unknown A” obsidian source has remained unknown. In 2006, during an archaeological reconnaissance of the upper Rio Sonoyta in northern Sonora, members of the Ajo Chapter of the Arizona Archaeological Society discovered a new obsidian source on a dome complex on the southeast side of the river basin near the previously recorded Los Vidrios. This new source was determined to match the elemental composition of AZ Unknown A. The source was mapped, sampled, and recorded in November 2008 by Martynec and Shackley, and a sample of the source material analyzed at the Berkeley Geoarchaeological XRF Laboratory. The petrology and chemistry of this newly discovered source are discussed as well as its archaeological context in the region.
