2018 Map of Circle B-1 SE

About this map

Steep, high-elevation terrain dominates this interior Alaska quadrangle within the Yukon-Koyukuk Census Area. The topography is defined by significant vertical relief, with numerous ridges and drainage systems branching out from central high points. The map area is organized across four township and range blocks, including T6n R17e, T6n R18e, T5n R17e, and T5n R18e. Absent of any named roads, settlements, or structures, the landscape represents a pristine wilderness environment. The contour lines, provided by the National Elevation Dataset, reveal a complex network of peaks and valleys, where the natural water flow is documented through the National Hydrography Dataset across this roadless expanse of the Alaskan interior.
