2019 Map of Ugashik B-4 SE

About this map

The Dog Salmon River meanders across a landscape defined by water and high relief in this remote section of the Aleutian Range. This 2019 survey documents a complex network of wetlands and oxbow lakes formed by the shifting course of the river, which dominates the central and northern portions of the quadrangle. As the river flows through these low-lying reaches, it is fed by smaller tributaries like Wandering Creek, which winds through the southern terrain. This map serves as a primary record of the hydrological patterns and topographic contours of the Alaska Peninsula, illustrating the transition from steep mountain slopes to the saturated river basins. The lack of roads or established settlements emphasizes the wilderness character of the Lake and Peninsula Borough, where the natural drainage of the Dog Salmon River remains the primary geographical feature.
