About this map

Susitna Flats dominates the southern reaches of this landscape where the marshy coastal lowlands meet the Knik Arm. This 1950s environment is defined by an intricate network of drainage and delta systems, most notably the Little Susitna River and the Little River, which wind through vast wetlands and muskeg. Human presence is sparse and functional, concentrated around a small Airstrip and Radio Towers situated near the center of the sheet. Inland, the terrain is dotted with numerous small bodies of water such as Horseshoe Lake, Twin Island Lake, and Yohn Lake. Evidence of early exploration and access is visible through the primitive Tractor Trail that cuts across the northeastern section, while several isolated Cabin sites and Cabins suggest remote seasonal dwellings or hunting camps tucked away near the shores of Lost Lake and other watercourses.
