2019 Map of McGrath B-6 SW

USGS Topo · Published 2019

About this map

First Fork Selatna River snakes through the high-elevation interior of the Yukon-Koyukuk region, defining the primary drainage pattern of this sub-arctic landscape. This 2019 survey documents the complex topography of the Alaska interior, where the land is divided by the Public Land Survey System into townships like t26n r36w and t26n r35w. The map reveals a high-relief environment dominated by steep ridges and deep valleys, captured using 10-foot contour intervals that show the fine-grained physical geography of the First Fork Selatna River basin. In a region with no established road network or permanent settlements, these hydrological features and survey boundaries remain the primary landmarks for navigation and land management.
