2017 Map of Philip Smith Mountains B-4 SE

About this map

Philip Smith Mountains define the topography of this high-latitude terrain, where the massive ridgelines and drainage patterns of the Brooks Range are documented with modern precision. The eastern edge of the sheet is dominated by the braided corridor of the Sagavanirktok River, a vital Arctic waterway that historically served as a primary travel route through the northern interior. This 2017 survey details the complex hydrography of the river's floodplains and the surrounding high-elevation basins, providing an essential record of the landscape's structure. The map captures the raw intersection of geological features and the vast hydrological network that shapes the North Slope, offering researchers a clear look at the physical geography before any significant human development or permanent infrastructure altered these remote sections of the mountains.
