Dynamics of obsidian procurement at Pot Creek Pueblo (LA 260), Northern New Mexico

We present obsidian sourcing data from Pot Creek Pueblo (LA 260), one of the northernmost Puebloan settlements in the Northern Rio Grande, occupied from at least 1260 ce until ca. 1320 ce when much of the pueblo was burned and the site was depopulated. Although the occupation of Pot Creek Pueblo was...

Sumario:We present obsidian sourcing data from Pot Creek Pueblo (LA 260), one of the northernmost Puebloan settlements in the Northern Rio Grande, occupied from at least 1260 ce until ca. 1320 ce when much of the pueblo was burned and the site was depopulated. Although the occupation of Pot Creek Pueblo was short, it occurred during a pivotal period in the Northern Rio Grande. The population of the region increased rapidly at this time, possibly due to an influx of migrants from the Mesa Verde/San Juan area to the west, and locally people living in relatively small villages comprised of pithouses and above-ground unit pueblos begin to coalesce into fewer, but much larger above-ground pueblos. Obsidian-source choices throughout the region may provide insight into how the proposed migration impacted existing resource-procurement patterns. Our data demonstrate that despite the diverse histories of the settlement’s inhabitants, the exchange system supplying obsidian to Pot Creek Pueblo remained stable throughout its occupation. We argue that exchange dynamics of the local community remained the primary means of obtaining obsidian despite potential for new avenues that might have been available through the addition of new community members from outside the region and despite population growth and changing settlement patterns in the broader Northern Rio Grande.
