1971 Map of Philip Smith Mountains C-1

About this map

The Continental Divide winds through this high-latitude terrain, marking the hydrological boundary where waters part to flow toward different drainage basins. This 1971 survey captures a landscape defined entirely by its glacial and fluvial systems, with no roads or trails recorded. High-altitude ice fields like Windy Glacier and Seefer Glacier feed the headwaters of several major waterways. The Lupine River and Ribdon River dominate the northern drainage, while the southern slopes give rise to the Wind River and Junjik River. The intricate contouring illustrates the complex alpine topography of the Brooks Range, where the Ivishak River carves deep paths through the mountain massifs. This document preserves the state of these arctic watersheds just as modern photogrammetric mapping was becoming standard for the North Slope.
