2019 Map of McGrath A-6 SE

About this map

The Tatlawiksuk River meanders across this northern landscape, defining the topography of an area where the Yukon-Koyukuk Census Area and Bethel Census Area meet. The terrain is characterized by significant elevation changes, with the river valley cutting through upland regions marked by Public Land Survey System township boundaries such as t23n r35w and t24n r34w. This 2019 survey documents a largely undeveloped wilderness in the McGrath region, where the natural watercourse remains the primary geographical landmark. The absence of roads or established settlements on the sheet highlights the isolation of this interior river system, making it a critical reference for understanding the modern jurisdictional boundaries and natural hydrology of the Alaskan interior.
