The following article outlines a collaborative, multidisciplinary approach to remote sensing in Southwest Alaska's Yukon-Kuskokwim (Y-K) Delta that combines ethnographic inquiry and remote sensing to monitor, detect and preserve cultural resources for Alaskan Native communities. Because distinctive vegetation differences are readily visible on cultural sites during the summer months, the analysis of multispectral imagery obtained from remote sensing is particularly useful. In turn, we demonstrate the efficacy of this protocol on pre-contact settlement sites along the Ayakulik River system on Kodiak Island using a normalized difference vegetation index (NDVI) raster of the study area. Here, support vector machine (SVM) supervised classification was highly effective at identifying spectral patterns associated with anthropogenic activity while ethnographic data helped rule out false-positive cases. In addition, we provide the results of a 2019 archaeological prospection survey carried out in conjunction with the ongoing Nunalleq Project in Quinhagak, Alaska, to further highlight the value of ethnographic data collection, ethnobotanical surveys and unmanned aerial vehicle (UAV)-based spectroscopy alongside SVM supervised classification. Finally, we propose three suggestions for future research on Yup'ik landscapes in the Y-K Delta regarding citizen science, language preservation and the use of collaborative online maps for community-based decision making.

The Yukon-Kuskokwim (Y-K) Delta is home to the Alaskan Native Yup’ik people who have inhabited this remote, subarctic tundra for over 1500 years. Today, their ancestral lifeways and cultural landscapes are at risk from severe climate change-related threats. In turn, we propose that remote sensing technologies, particularly with sensors mounted on Unmanned Aerial Vehicle (UAV) platforms, are uniquely suited for protecting Yup’ik landscape heritage. Based on collaborative, community-based fieldwork in Quinhagak, AK, we present evidence that cultural sites—ranging from historic fishing camps to pre-contact winter villages—exhibit predictably atypical vegetation patterns based on the local ecological biome. Furthermore, these vegetation patterns can be recorded and statistically quantified through the analysis of multispectral imagery obtained from UAV-mounted sensors with three different false color composite rasters and vegetation indices depending on biome type. Finally, we suggest how the Yupiit can combine these methodologies/workflows with local knowledge to monitor the broader heritage landscape in the face of climate change.

This essay—based on fieldwork with off-grid homebuilders in the Mid-Ohio River Valley—recognizes ethnography as a more-than-human ecology of habit, rhythm, and affect. I begin by describing some of the materials, species, and affects I encountered during this fieldwork to show how Appalachian history, geography, and habit influenced my performance of sensory ethnography. From these anecdotes, field notes, and vignettes, I theorize ethnographic fieldwork as, first and foremost, a rhythmic attunement to place and bodies, especially nonhuman ones. In turn, I argue for a practice of fieldwork that roots human experience within a vibrant material ecology of more-than-human forces.

After the United States’ purchase of Alaska from Russia in 1867, Alaska Native lands have existed in a legal state of aboriginal title, whereby the land rights of its traditional occupants could be extinguished by Congress at any time. With the passage of the Alaska Native Claims Settlement Act (ANCSA) in 1971, however, Alaska Native individuals were given the opportunity to select and secure a title to ancestral lands as federally administered ANCSA 14(c) allotments. Today, though, these allotments are threatened by climate-change-driven erosion. In response, our article provides an erosion monitoring tool to quantify the damage caused by coastal and riverine erosion. Using the Yup’ik (pl. Yupiit) community of Quinhagak as a case study, we employ high-precision measurement devices and archival spatial datasets to demonstrate the immense scale of the loss of cultural lands in this region. From 1976 to 2022, an average of 30.87 m of coastline were lost according to 9 ANCSA 14(c) case studies within Quinhagak’s Traditional Land Use Area. In response, we present a free erosion monitoring tool and urge tribal entities in Alaska to replicate our methods for recording and quantifying erosion on their shareholders’ ANCSA 14(c) properties. Doing so will foster urgent dialogue between Alaskan Native communities and lawmakers to determine what measures are needed to protect Alaska Native land rights in the face of new environmental challenges.
