2017 Map of McGrath B-1 NE

About this map

The Jones River winds through this high-altitude landscape of the Alaska interior, serving as the dominant hydrologic feature across a vast expanse of undeveloped terrain. Located at the boundary between the Yukon-Koyukuk Census Area and the Matanuska-Susitna Borough, the map illustrates a complex series of drainage patterns and elevation changes. In the southeastern corner, the Tatlina River makes a brief appearance, cutting through the lower slopes. The topography is defined by significant vertical relief, where steep ridges and deep valleys dictate the movement of water and would historicaly have guided any overland travel or prospecting efforts in the region. This 2017 study details the precise geographic coordinates of the Public Land Survey System, including t28n r21w and t27n r20w, providing a structural grid for this remote wilderness.
