2019 Map of McGrath A-5 NE

About this map

The Public Land Survey System divisions of T25n R32w, T25n R31w, and T24n R32w reveal a complex, undeveloped landscape in the Yukon-Koyukuk region of Alaska. This 2019 survey, produced by the U.S. Geological Survey using SPOT imagery and National Elevation Dataset contours, documents the intricate drainage patterns and rising elevations characteristic of the McGrath A-5 NE quadrangle. The map is notably sparse, lacking any named settlements, schools, cemeteries, or roads, illustrating the profound isolation of this wilderness area near the southern interior of Alaska. Instead, the topography is defined by the rigid grid of the township and range system, which provides the only human-imposed structure to this otherwise trackless terrain. Researchers can use the 20-foot contour intervals to trace the sharp relief and natural hydrology of the Kuskokwim River drainage area.
