2015 Map of Ophir D-6 SW

USGS Topo · Published 2015

About this map

The remote interior of Alaska's Yukon-Koyukuk region is defined by a landscape of extreme transitions, where low-lying drainage basins meet rising upland terrain. This 2015 survey reveals an area largely untouched by modern infrastructure, mapped according to the Public Land Survey System boundaries of T19s R1w and T19s R2w. The northern sections of the map are dominated by meandering watercourses and wetlands, while the southern reaches transition into more complex elevation contours as the land gains height toward the eastern limits of T19s R1e. Without named settlements or roads, the map serves as a primary record of the natural topography and the precisely surveyed township lines, including T20s R1w and T20s R2w, which govern this wilderness. It is an essential document for understanding the geographic layout of the Ophir quadrangle before any significant human development altered the terrain.
