2018 Map of Coleen B-2 NW

About this map

U.S. Department of the Interior surveyors documented this interior reach of the Yukon-Koyukuk Census Area, a landscape defined by dramatic elevation changes and subarctic wetlands. The mapping of T31n R26e, T31n R27e, T30n R26e, and T30n R27e shows a territory largely devoid of established roads or settlements, where the topographic relief provides the primary landmarks. Contour lines reveal a series of prominent peaks and ridgelines separated by low-lying basins containing scattered ponds and drainage networks. The lack of modern infrastructure highlights the area's isolation within the larger Coleen River region, where land use is dictated by the challenging terrain and the presence of private holdings within government reservations.
