1971 Map of Philip Smith Mountains A-3

About this map

The Continental Divide defines the hydrological spine of this high-latitude terrain, where waters separate toward the North Slope. Winding through the central and southern valleys, Your Creek serves as the primary drainage for the area, its path captured via photogrammetric methods from aerial photographs taken in 1970. This 1:63,360 scale study illustrates a landscape where human influence is minimal, marked primarily by the administrative lines of the Borough Boundary and the South Boundary Umiat Meridian. The map captures a transition point in the mapping of northern Alaska, reflecting land lines that at the time represented unsurveyed and unmarked locations predetermined by the Bureau of Land Management.
