A Council Circle at Etzanoa? Multi-sensor Drone Survey at an Ancestral Wichita Settlement in Southeastern Kansas (Article)

Abstract: This article presents results of a multi-sensor drone survey at an ancestral Wichita archaeological site in southeastern Kansas, originally recorded in the 1930s and believed by some scholars to be the location of historical “Etzanoa,” a major settlement reportedly encountered by Spanish conquistador Juan de Oñate in 1601.We used high-resolution, drone-acquired thermal and multispectral (color and near-infrared) imagery, alongside publicly available lidar data and satellite imagery, to prospect for archaeological features across a relatively undisturbed 18 ha area of the site. Results reveal a feature that is best interpreted as the remains of a large, circular earthwork, similar to so-called council circles documented at five other contemporary sites of the Great Bend aspect cultural assemblage. We also located several features that may be remains of house basins, the size and configuration of which conform with historical evidence. These findings point to major investment in the construction of largescale ritual, elite, or defensive structures, lending support to the interpretation of the cluster of Great Bend aspect sites in the lower Walnut River as a single, sprawling population center, as well as demonstrating the potential for thermal and multispectral surveys to reveal archaeological landscape features in the Great Plains and beyond.

Archaeological Remote Sensing Using Multi-Temporal, Drone-Acquired Thermal and Near Infrared (NIR) Imagery: A Case Study at the Enfield Shaker Village, New Hampshire (Article)

Abstract: While archaeologists have long understood that thermal and multi-spectral imagery can potentially reveal a wide range of ancient cultural landscape features, only recently have advances in drone and sensor technology enabled us to collect these data at sufficiently high spatial and temporal resolution for archaeological field settings. This paper presents results of a study at the Enfield Shaker Village, New Hampshire (USA), in which we collect a time-series of multi-spectral visible light, near-infrared (NIR), and thermal imagery in order to better understand the optimal contexts and environmental conditions for various sensors. We present new methods to remove noise from imagery and to combine multiple raster datasets in order to improve archaeological feature visibility. Analysis compares results of aerial imaging with ground-penetrating radar and magnetic gradiometry surveys, illustrating the complementary nature of these distinct remote sensing methods. Results demonstrate the value of high-resolution thermal and NIR imagery, as well as of multi-temporal image analysis, for the detection of archaeological features on and below the ground surface, offering an improved set of methods for the integration of these emerging technologies into archaeological field investigations.

Detecting Prehistoric Landscape Features Using Thermal, Multispectral, and Historical Imagery Analysis at Midewin National Tallgrass Prairie, Illinois (Article)

Abstract: Locating the subtle and uneven deposition of human activities across the landscape continues to challenge archaeologists. Existing tools (e.g. excavation, shovel testing, pedestrian survey, and terrestrial geophysics) have proven effective at locating many types of archaeological features but remain time-consuming and difficult to undertake on densely vegetated or topographically complex terrain. As a result of these limitations, key aspects of past communities remain largely outside of archaeological detection and interpretation. This flattening of past lifeways not only affects broader understandings of these communities, but can also negatively impact the preservation of archaeological sites. This paper presents the detection of archaeological features through an analysis of drone-acquired thermal, multispectral, and visible light imagery, alongside historical aerial photography, in the area surrounding Middle Grant Creek (11WI2739), a late prehistoric village located at Midewin National Tallgrass Prairie in Will County, IL. Our investigations discovered a probable housing area and a ritual enclosure, increasing the area of the site from 3.4 ha to 20 ha. The proposed housing and ritual areas of this village also help contextualize finds from the ongoing archaeological excavations at Middle Grant Creek. More broadly, results demonstrate the valuable contributions that these relatively new archaeological survey methods have in shaping our understandings of the archaeological landscape and highlight the importance of integrating them into the archaeological toolkit.

Archaeological Aerial Thermography in Theory and Practice (Article)

Abstract: While a long history of experimental data shows that aerial thermal images can reveal a wide range of both surface and subsurface archaeological features, technological hurdles have largely prevented more widespread use of this promising prospecting method. However, recent advances in the sophistication of thermal cameras, the reliability of commercial drones, and the growing power of photogrammetric software packages are revolutionizing archaeologists' ability to collect, process, and analyze aerial thermal imagery. This paper provides an overview of the theory behind aerial thermography in archaeology, as well as a discussion of an emerging set of methods developed by the authors for undertaking successful surveys. Summarizing investigations at archaeological sites in North America, the Mediterranean, and the Near East, our results illustrate some contexts in which aerial thermography is very effective, as well as cases in which ground cover, soil composition, or the depth and character of archaeological features present challenges. In addition, we highlight novel approaches for filtering out noise caused by vegetation, as well as methods for improving feature visibility using radiometric thermal imagery.
