2020 Map of Lookout Ridge D-1 SW

USGS Topo · Published 2020

About this map

The Topagoruk River winds through the northern tundra of this Arctic landscape, creating a serpentine drainage pattern across the coastal plain. Surveyed in the early 21st century, the map details the subtle elevation changes of the North Slope, where the river's path is the primary geographical anchor across township lines like t6n r19w and t5n r18w. The absence of roads or established settlements emphasizes the isolated character of this region, which remains largely defined by its natural hydrology and the expansive public land divisions of the National Petroleum Reserve. This topographic study provides a baseline of the permafrost-influenced terrain and the meandering watercourses that dominate the northern Alaskan interior.
