The Ponglevik River winds through this section of the Kusilvak Census Area in western Alaska. Mapped in 2020, the sheet illustrates a landscape shaped by complex hydrography and wetland systems common to the Yukon-Kuskokwim Delta. While the area lacks developed settlements, the precise topographic data documents the intricate watercourses and myriad small lakes across the region. Surveyed at a 1:25,000 scale, the map is useful for understanding the hydrologic patterns and land divisions within the T25n R83w and T24n R83w townships. Researchers examining environmental changes or specific land allotments in Alaska can use these detailed contours and water boundaries to track local shifts over time.
