Dr. Surovell’s excavations at Barger Gulch in Grand County, Colorado yielded numerous spatial patterns in chipped stone artifacts in interior and exterior spaces of a Folsom campsite.  While spatial patterns were easy to identify, Todd found it challenging to link those patterns back to the human behaviors that produced them.  His inability to confidently interpret the behavioral significance of archaeological patterns is what led to the desire to actually observe living nomadic peoples, ultimately with the intent of understanding how human behavior is organized spatially at small scales in nomadic contexts. The Dukha Ethnoarchaeological Project was born from that simple idea.  Over six field seasons from 2012 to 2017, Todd  lived with Dukha reindeer herders in the taiga of the Sayan Mountains in far northern Mongolia and mapped people and their activities in a half dozen Dukha campsites.  In this talk, Dr. Surovell will present an ethnographic overview of the Dukha people, talk about some of the things he learned about how people use space, and how those findings might help us to interpret archaeological spatial patterns.
