2018 Map of Christian A-4 SW

USGS Topo · Published 2018

About this map

Marten Cr defines the drainage pattern of this landscape in the northern Alaskan interior. This 2018 survey emphasizes the immense scale of the public land system, delineating the boundaries of several townships including t27n r8e and t26n r9e. The map illustrates a complex network of wetlands and small ponds scattered across the low-lying southern sections, contrasting with the rising elevations of the interior hills to the north. While the area lacks established roads or settlements, the topography reveals the natural corridors formed by watercourses like Marten Cr as they cut through the Yukon-Koyukuk region. Researchers can trace the precise contours and survey lines that divide these vast tracts of subarctic wilderness.
