1971 Map of Philip Smith Mountains B-1

About this map

Continental Divide crests through the high terrain of the North Slope in this 1971 aerial survey, marking a significant hydrologic boundary in a region devoid of roads or permanent settlements. The map documents a primitive drainage system defined by the Wind River, which meanders through the central and southern sections, and the Junjik River in the northeast. Small tributaries like Smoke Creek feed these larger arteries, illustrating the complex watershed patterns characteristic of the Brooks Range interior. Prepared by the Geological Survey from 1970 photogrammetric data, this advance proof illustrates the landscape before modern infrastructure reached this part of the Alaskan wilderness, offering a precise look at the natural watercourses and relief as recorded before field checking.
