2018 Map of Fort Yukon B-4 SE

About this map

Upper Mouth Birch Creek and Lower Mouth Birch Creek dominate this subarctic landscape within the Yukon-Koyukuk region. The area is characterized by an intricate network of wetlands and meanders, illustrating the dynamic hydrology of the Alaskan interior where river systems frequently shift and braid across the low-lying terrain. The presence of Hat-lie-Lakes in the northeastern quadrant suggests a series of thaw lakes common in permafrost-affected regions, providing critical habitat within the larger watershed. Further south, the map details the path of Discovery Creek, which joins the larger aquatic system amidst a complex of unnamed ponds and marshes. This 2018 survey captures the contemporary state of these waterways before seasonal flooding or long-term climatic shifts alter the fragile drainage patterns of the boreal wilderness.
