1971 Map of Philip Smith Mountains A-1

USGS Topo · Published 1974

About this map

The West Fork Sagavanirktok River meanders through the high-altitude terrain of the North Slope in this early 1970s topographic study. The landscape is defined by its glacial hydrology, where the river valley creates a break in the mountainous topography, accompanied by numerous unnamed alpine lakes and marshy lowlands. This advance proof map captures the area shortly after 1970 aerial photography, documenting the unsurveyed and unmarked locations predetermined by the Bureau of Land Management. The northern extent of the South Boundary Umiat Meridian provides a primary reference for the remote interior, showing a region devoid of permanent settlements or infrastructure at the time of the survey.
