About this map

Susitna sits at the eastern edge of a landscape defined by braided waterways and glacial drainages within the Matanuska-Susitna Borough. This modern data illustrates the intricate hydrography of the region, where the Lewis River and Ivan River flow through a complex network of wetlands and shifting channels toward the Cook Inlet. To the northeast, the terrain rises sharply toward South Peak, providing a stark contrast between the low-lying river plains and the higher elevations of the surrounding mountains. The presence of Wolverine Creek further highlights the delicate balance of this watery environment, which remains largely roadless and dominated by natural processes. The map provides a contemporary perspective on the township and range divisions, specifically t16n r9w and t15n r8w, which organize this expansive subarctic wilderness.
