About this map

Lower Mouth Birch Creek flows through the northern reaches of this landscape, a remote section of the Yukon-Koyukuk region characterized by expansive wetlands and a complex system of interior lakes. The hydrography of the area is defined by significant bodies of water such as Chloya Lake and the interconnected waters of Three Lakes, which sit amidst the low-lying terrain typical of this subarctic environment. To the east, Twin Island Lake provides a distinct geographic landmark within the survey area.

The map reveals the transition from the lake-dotted lowlands in the north to more varied topographic relief in the southern sections, specifically within the boundaries of t15n r8e and t15n r9e. This 2018 survey by the U.S. Geological Survey reflects the enduring wilderness of the region, where natural drainage patterns and seasonal wetlands remain the dominant features, largely untouched by permanent road infrastructure or established settlements.
