About this map

The Kuskokwim River enters the northwestern corner of this territory, providing a major drainage route through a landscape primarily defined by high-elevation contours. The topographical data for this region in the Yukon-Koyukuk Census Area reveals a complex system of ridges and valleys that dictate the flow of smaller tributaries. Toward the southeast, the First Fork Selatna River snakes through the lower elevations, eventually joining the larger regional water systems. This map captures the unpopulated interior of Alaska, where the Public Land Survey System grids, such as t27n r36w and t27n r35w, provide the only formal structure across the expansive terrain. The absence of named settlements or roads underscores the wilderness character of the area, emphasizing its importance for hydrological study and remote navigation.
