1971 Map of Philip Smith Mountains A-2

USGS Topo · Published 1975

About this map

The Middle Fork Chandalar River dominates the eastern drainage of this high-latitude terrain within the Philip Smith Mountains. Surveyed via photogrammetric methods in the early 1970s, the map reveals a landscape defined by sharp elevation shifts and glacial drainages rather than human settlement. The southern portion of the sheet is marked by the Umiat Meridian and a formal Borough Boundary, indicating the administrative divisions of the North Slope. These land lines represent unsurveyed and unmarked locations, as the area remained largely inaccessible and devoid of established roads or permanent structures at the time of the field annotation.
