2014 Map of Wainwright A-4 SW

About this map

Tunalik River winds through the tundra of the North Slope, defining the primary drainage for this remote arctic landscape. In this 2014 survey, the river is captured in its meandering course, surrounded by a complex network of seasonal lakes and wetlands characteristic of the permafrost terrain. The map's detail highlights the vast hydrological system of the region, where numerous unnamed water bodies feed into the main river channel. The absence of roads or established settlements on this sheet reflects the untouched character of the North Slope Borough, where the natural topography remains the dominant feature of the land. It provides a technical view of the Tunalik River basin as it appeared in the early 21st century, documented by the U.S. Geological Survey through modern satellite imagery and national hydrography data.
