About this map

U.S. Geological Survey mapping of this interior Alaskan landscape highlights the intricate hydrology and wetlands of the Yukon-Koyukuk region. The sheet is defined by the Public Land Survey System grids, specifically tracking the boundaries between T15n R10e and T14n R10e. This terrain is characterized by a dense network of unnamed lakes and marshy lowlands, typical of the floodplains and permafrost-influenced basins found north of the Arctic Circle.

While no permanent settlements or named human-made landmarks are recorded in this specific sector, the map provides a precise record of the natural hydrography and elevation contours as they existed during the early 21st century. The intersection of townships like T15n R9e and T15n R11e serves as the primary organizational structure for this uninhabited wilderness, offering a baseline for environmental study or land management research.
