2017 Map of Tyonek C-6 NE

About this map

Trimble River flows through this high-altitude landscape in the Matanuska-Susitna Borough, defining the western drainage patterns of a region dominated by glacial terrain and steep contour gradients. In the northeast, the topographic layout highlights Hayes River Pass, a significant geographical corridor situated near Entrance Point. The map provides a detailed look at the hydrology of the area, including the upper reaches of Coal Cr. This 2017 survey reflects the remote wilderness of south-central Alaska, where the Public Land Survey System grids of t19n r15w and t18n r15w meet. The absence of roads or permanent settlements emphasizes the role of these natural landmarks as primary navigational references for bush pilots and backcountry travelers.
