About this map

Salmon Island and the surrounding riverine landscape define this area of the Yukon-Koyukuk region, where complex water systems dominate the terrain. The Yukon River flows along the western edge of the quadrangle, serving as a primary corridor for travel and subsistence in this part of Alaska. To the east, the Innoko River meanders through a labyrinth of secondary channels, including the Innoko Slough and Paimiut Slough. The intricate network of waterways, characterized by features like Red-Wind-Slough, illustrates a dynamic environment shaped by seasonal hydrological shifts. This survey documents the intersection of these major river systems before further natural or man-made changes, providing a clear record of the channels and islands that local residents and researchers rely upon for navigation and land use.
