2018 Map of Circle B-1 SW
USGS Topo · Published 2018About this map
Birch Creek dominates the interior of this remote Interior Alaska landscape, winding through a complex system of ridges and valleys within the Yukon-Koyukuk region. The water system is further defined by the S Fork Birch Cr and Big Windy Cr, which drain the surrounding highlands. This 2018 survey illustrates the untouched character of the subarctic wilderness, where no roads or permanent settlements are recorded. The terrain is divided by the Public Land Survey System grids of t6n r16e, t6n r17e, t5n r16e, and t5n r17e, providing a precise framework for the undeveloped land. For researchers and conservationists, the map reveals the natural drainage patterns and the elevation changes that define this portion of the Circle mining district hinterlands.
