About this map

The Yukon River dominates this interior landscape, carving a complex network of channels and braided streams through the Yukon-Koyukuk region. The main waterway is subdivided into the Yukon River Main Channel, Western Channel, and East Channel, creating a series of large, named landmasses including Florence Island, Edith Island, and Novakaket Island. The confluence with the Nowitna River in the southeast corner further complicates the aquatic geography, where river dynamics are recorded at specific landmarks like Mouse Point and Cross Point. This 2019 survey documents a wilderness environment shaped by seasonal water movement, where seasonal sloughs such as Victor Slough and Novakaket Slough weave between the larger riverbanks. The terrain is characterized by the expansive Big Bend of the Yukon and the drainage of smaller tributaries like Ukawutni Cr and Junekaket Creek.
