2019 Map of McGrath C-5 SE
USGS Topo · Published 2019About this map
Katlitna River and Big River dominate this interior Alaskan landscape within the Yukon-Koyukuk region. This 2019 survey captures a complex network of wetlands and seasonal watercourses, where the braided channels of the Big River flow alongside countless unnamed ponds and marshy depressions. The Blackwater Cr meanders through the central terrain, serving as a primary drainage between the larger river systems. This area is characterized by the absence of permanent settlements or road infrastructure, defined instead by the Public Land Survey System boundaries of t29n r32w and t28n r31w. The topography is relatively flat, with subtle elevation changes indicated by ten-foot contour intervals, revealing the delicate hydrology of this subarctic river basin.
