A piece of mahogany obsidian came to the attention of the senior author during an excavation project near the town of Mata Ortiz, Chihuahua, Mexico in 2015. Because mahogany obsidian in northwestern Mexico is particularly rare, the question was raised, what obsidian source did this sample derive? Here, using energy-dispersive X-ray fluorescence (EDXRF) spectrometry, we demonstrate it comes from the Agua Fria obsidian source in northeastern Sonora, Mexico. Unfortunately, we do not know where this sample was collected from. We discuss these results and the significance of this find in this paper, but more investigation is certainly warranted.
