Chandalar Cr and Grayling Cr define the hydrological landscape of this remote Yukon-Koyukuk Census Area interior. In this 2018 survey, the terrain is characterized by high-elevation ridges and deep creek valleys, with watercourses moving through the township boundaries of t30n r19e and t31n r20e. The absence of roads, trails, or structures emphasizes the isolation of the Brooks Range foothills, where Boulder Cr flows through the northern reaches of the quadrangle. This map serves as a contemporary record of the hydrography and topography in an area of Alaska where the natural drainage patterns remains the primary geographic markers.
