2017 Map of Tyonek D-5 NW

About this map

The Skwentna River dominates this Alaskan landscape, carving a wide braided path across the central valley. This 2017 survey reveals the intricate hydrography of the Matanuska-Susitna region, where the Hayes River joins the main flow amidst an expansive network of wetlands and seasonal floodplains. The terrain transitions from the low-lying river basins in the north to the rising elevation of the southern townships, defined by the t21n r14w and t21n r13w boundary markers. Smaller drainages like Shell Cr in the far north and Contact Cr at the southern edge provide specific points of reference for navigating this unpopulated wilderness area, illustrating the natural state of the upper Susitna drainage system before any modern development or infrastructure.
