2019 Map of Ruby A-2 SW

About this map

The interior wilderness of the Yukon-Koyukuk Census Area is defined here by the systematic grids of the Public Land Survey System, specifically marking the meeting of T16s R25e, T16s R26e, T17s R25e, and T17s R26e. This 2019 survey documents a landscape of high-altitude ridgelines and drainage basins, reflecting the deep isolation of central Alaska. The topography is dominated by steep contour lines that illustrate the elevation changes of the Ruby A-2 SW region, where the absence of named human settlements or infrastructure highlights the raw, undeveloped character of the territory. This map serves as a primary record of the terrain as it existed in the early 21st century, providing essential geographic data for a region where physical landmarks are defined by the earth rather than by industry or habitation.
