Boulder Cr flows through the northern reaches of this map, winding through the expansive interior of the Yukon-Koyukuk Census Area. This 2018 survey by the U.S. Geological Survey focuses on a largely uninhabited landscape, dominated by the natural drainage patterns of the region. The map provides a detailed study of the terrain across four primary townships: T31n R18e, T31n R19e, T30n R18e, and T30n R19e. Without roads or settlements, the topography itself becomes the primary subject, illustrating the remote and untouched character of northern Alaska as it remained in the early 21st century. Researchers and collectors of Alaskan geography can trace the specific course of the creek and its relationship to the surrounding elevation contours.
