This study was supported by the Alaska Division of Geological & Geophysical Surveys (DGGS) under the direction of Rod Combellick. Field research at Sarichef Island in 1992 and 1993 was supported by the U.S. Department of the Interior, National Park Service, through its Beringian Shared Heritage Project. The field-work component of this research benefited from the insight and hospitality of Clifford Weyiowanna of Shishmaref and Charles Newberg, City Clerk of Shishmaref. Helicopter support was provided by the National Park Service, Bering Land Bridge National Preserve office in Nome through research coordinator Rich Harris. Patricia Heiser (Ph.D. student, Department of Geology, University of Alaska Fairbanks) and Douglas Van Patten (U.S. Department of Agriculture, Soil Conservation Service, Homer, Alaska) provided unpublished data on the surficial geology and soils of northern Seward Peninsula. James Jordan (Ph.D. student, Department of Geography, University of Wisconsin) participated in 1992 and 1993 field studies and commented on ideas expressed in the text. Combellick and Heiser reviewed the draft report. Sean Weems (DGGS) used electronic cartography to construct finished map from a hand-drafted photointerpretive geologic map. Orrin PiLkey (Duke University Program for the Study of Developed Shorelines) provided funds and accompanied DGGS staff to Shishmaref in summer 1992. Kinney Engineering, LLC staff compiled the data into into the GeMS format and provided cartographic support. Chris Wyatt and Ally M. Steinleitner quality controlled, and then finalized the GeMS database. This geologic map (or report or conversion or product, etc.) was funded by the USGS National Cooperative Geologic Mapping Program under STATEMAP award number G23AC00584, 2023, and the State of Alaska General Fund.

Storm erosion and flooding along the Chukchi Sea coast have raised serious concerns among residents of Shishmaref about the future of their communities. As storms continue, residents witness their island visibly shrinking. Long-term erosion rates remain poorly documented, though each storm can result in several meters of bluff collapse. Assessing the sedimentary characteristics and engineering properties of potential relocation sites suggested by the City of Shishmaref is crucial. Geotechnical studies provide valuable insights to support informed decision-making.
