2019 Map of McGrath D-1 NE

About this map

Tonzona River and the Little Tonzona River carve through this remote Alaskan interior landscape, defining a complex drainage system within the Unorganized Borough. This 2019 survey captures a wilderness dominated by hydrographic networks, where the Clear Fork and Pingston Creek (also labeled as Pingston Cr) meander through township and range sections that show no established road infrastructure or permanent settlements. The map's detail is focused on the subtle topographic shifts of the river basins, including the headwaters of Jones Cr and its northern fork. This documentation of the Medfra and McGrath quadrangle boundary areas is essential for understanding the hydrological connectivity of the region, providing a baseline for the natural drainage patterns of the N Fork Jones Cr and surrounding tributaries.
