2017 Map of Sagavanirktok D-4 SE

About this map

Hydrological patterns and permafrost features dominate this Arctic landscape within the North Slope Borough, where the vast majority of the terrain is defined by complex wetland systems. Surveyed by the U.S. Geological Survey using satellite imagery from 2010 and hydrography data updated through 2016, the map reveals a remote wilderness devoid of established roads or permanent settlements. The sheet is primarily organized by the Public Land Survey System grid, covering portions of T6n R12e, T6n R13e, T5n R12e, and T5n R13e. The density of thaw lakes and ponds illustrates a landscape in constant flux, where small water bodies and marshy lowlands create a non-linear network across the tundra, providing critical data for researchers tracking environmental changes in the northernmost reaches of Alaska.
