About this map

The Yukon River dominates the southern half of this interior landscape, winding through a high-relief basin in the Yukon-Koyukuk region. In the southeast, Kalka Island sits within the wide river channel, providing a rare landmark in the waterway. The surrounding terrain is defined by steep ridges and drainages that feed into the main river system, such as Little Salt Cr, which cuts through the northern uplands. This 2017 survey illustrates a largely unpopulated wilderness, focused on the primary natural corridors that have historically served as the main transportation routes through the Alaskan interior. The absence of roads or settlements highlights the isolation of this reach of the Yukon, where the river's movement and the island's formation are the primary indicators of a changing landscape.
