1971 Map of Philip Smith Mountains A-1

About this map

The Wind River carves a path through this remote portion of the North Slope, documented here through 1970 aerial photography. The landscape is defined by its drainages and the South Boundary Umiat Meridian, representing a vast area of unsurveyed wilderness under the jurisdiction of the Bureau of Land Management. This 1971 study reveals a terrain of low-relief wetlands and swamps concentrated along the river corridor, highlighting the hydrologic patterns of the Arctic interior before significant modern development. The inclusion of the Borough Boundary provides a jurisdictional context for this uninhabited expanse, where the natural course of the water remains the primary geographical landmark.
