1954 Map of Tyonek D-2

About this map

The Kahiltna River and Yentna River dominate this mid-century landscape in the Matanuska-Susitna region, where complex glacial drainage patterns are evident across a vast expanse of wetlands. Surveyed in the early 1950s, the terrain is defined by its water-rich geography, including the lengthy course of Kroto Creek and smaller basins like Neil Lake and Lockwood Lake. Human presence is exceptionally sparse, marked only by isolated Cabins and surveying landmarks such as VABM 138 Moose. The intricate network of swamps and streams between Moose Creek and the larger river systems illustrates the unorganized and roadless nature of the Alaskan interior at this time, offering a clear view of the natural hydrology before any modern development or infrastructure altered the drainage basins.
