2016 Map of Tyonek D-7 NW

About this map

The Skwentna River winds through the northern reaches of this landscape, its wide channel and braided patterns indicating a dynamic glacial watercourse in the Matanuska-Susitna region. To the south, the terrain rises sharply toward the prominent Alger Peak, while the Chickak River flows northward through a narrow valley to join the larger Skwentna drainage. This 2016 survey captures the area's complex hydrology, including smaller tributaries like Portage Cr and Old Man Creek. The northern horizon is defined by the Long Lake Hills, where the relief begins to flatten. The map details the legal townships and ranges of the Alaska Public Land Survey System, specifically t22n r18w and t21n r18w, providing a precise framework for the undeveloped wilderness and its elevation contours.
