One of the primary ways we study the formation of human landscapes through time is with landscape archaeology. Members of the SAIE Lab direct archaeological surveys, excavations, analysis and GIS studies in a variety of ecologies spanning from the deserts of North Africa and Central Asia to the steppes and high mountains of Inner Eurasia, tracing human societies and their geography over the past 6000 years.
With support from the National Geographic Society, the SAIE Lab is using UAV based LiDAR for large scale geophysical survey to document the remains of an ancient medieval city at Tugunbulak, Uzbekistan. This can provide many new insights into our understanding of medieval mountain communities and their engagement in trade, production, and urban development along the ancient Silk Routes of Central Asia.
Archaeological excavations at the site complex of “Dali” – located in southeastern Kazakhstan – provide a rich picture of Bronze Age life spanning from the early third to late second millennia b.c. Nearly ten years of research at the site have produced an abundant assemblage of architectural remains, ritual and burial contexts, human and animal ancient DNA, as well as related economic, ceramic, and other forms of materiality.
As part of the collaborative work between SAIE lab and archaeologists from Sichuan University (founded by the National Social Science Fund of China), we conducted an analysis on the ceramic materials of the Bangga site. The excavations and analysis of Bangga site provided evidence that the site is an agropastoral settlement in the first millennium BC.
Through the innovative use of "flow accumulation", the SAIE lab study maps the annual migration routes of Inner Asian mountain pastoralists from elevations of 750m to 4,000m to shed light on the evolution of “Silk Roads.” After aggregating 500 model iterations, we uncovered a high-resolution flow network that simulates how centuries of seasonal nomadic herding could have shaped discrete routes of connectivity across the seemingly uncrossable mountains of Asia. This sheds light on the possibility that the elevated stretches of the Silk Road may have evolved from ancient nomadic herding trails in Inner Asia.
With support from the National Geographic Society, the SAIE Lab used high-tech analysis tools for groundbreaking research on an ancient city high in the mountains of Uzbekistan. Site-wide geophysical survey revealed the dense architectural structure of the town center, which spans roughly 7ha at its core. Urban features such as a central mound (citadel), a large industrial workshop area, and a cemetery with over 350 individual burials all frame Tashbulak within a broader syntax of medieval urbanism and early Islamic conversion in the region. Tashbulak is currently one of the only known high mountain town centers constructed and occupied during the time of the Qarakhanid Empire.
The site’s importance in the landscape of the Koksu River Valley can be indexed by two large associated cemeteries, Begash-2 and Begash-3, located close to the settlement. Test excavations in 2002 and 2005 revealed stone cist burials characteristic of the late Bronze Age, as well as kurgan burials that illustrate continuity use of the burial ground in the Iron Age (based on regional analogues).
