2013 Map of Tanacross A-1 NW

About this map

Glacial valleys and high-altitude terrain define this portion of the Unorganized Borough in eastern Alaska, as surveyed by the U.S. Geological Survey in 2013. The landscape is characterized by a high-resolution contour interval of 20 feet, revealing a complex network of ridges and drainage basins within the Tanacross A-1 NW quadrangle. While no named settlements or permanent human infrastructure appear on this specific sheet, the map provides precise data for the Public Land Survey System, marking the intersection of townships T 17 N and T 16 N and ranges R 21 E and R 22 E. This digital-age survey integrates high-resolution SPOT imagery and National Elevation Dataset contours, offering a technical baseline for tracking changes in the subarctic topography and hydrography over time.
