The landslide was one of 43 newly recognized features revealed through satellite remote sensing analysis in the Prince William Sound region (Schaefer et al., 2024). Eleven of these landslides pose potential hazards to infrastructure and communities, including tsunami generation. While satellite data confirmed slow deformation of the Maynard Mountain landslide, it did not resolve its size, volume, failure mechanism, or likelihood of rapid failure. This geologic map addresses that gap by delineating surficial features, structural geology, and geomorphic indicators that inform assessments of landslide depth, extent, movement history, and potential hazard. The mapped features provide a foundation for future modeling, monitoring, and risk mitigation efforts in the region. The dataset contains geologic, structural, stratigraphic, and geochronologic data organized according to the GeMS and AK GeMS mapping schemas. The complete report, geodatabase, and ESRI fonts and style files are available from the Alaska Division of Geological & Geophysical Surveys website: http://doi.org/10.14509/31430. Purpose: This map provides a detailed surficial-geologic and structural interpretation of the Maynard Mountain landslide in the Seward D-5 Quadrangle, southcentral Alaska. It supports hazard assessment by delineating geologic and geomorphic features that inform estimates of landslide size, depth, movement history, and potential failure mechanisms. The map addresses gaps identified in recent satellite remote sensing analyses and serves as a foundational dataset for future modeling, monitoring, and risk mitigation efforts in the Prince William Sound region.
