Grass River and Sucker River define this subarctic wetland environment within the Yukon-Koyukuk Census Area. The landscape is dominated by complex hydrological patterns, with numerous unnamed ponds and marshy reaches typical of the interior Alaska river systems. The Grass River meanders across the northern portion of the quadrangle, while the Sucker River occupies the southeastern corner. This area remains largely undeveloped, with no named settlements or roads indicated on the 2018 survey. The map serves as a detailed record of the shifting watercourses and wetlands that characterize this portion of the Yukon Flats, providing essential data for those studying the natural history and environmental changes of the Alaskan interior.
