2016 Map of Tyonek D-3 SW

About this map

Deep Creek and Fox Creek define the central drainage patterns of this remote Matanuska-Susitna Borough landscape, where the terrain is dominated by a complex network of wetlands and small kettle lakes. This 2016 survey, produced by the U.S. Geological Survey, illustrates the untamed topography of Southcentral Alaska before significant modern infrastructure reached this specific interior region. The map reveals the low-lying hydrology typical of the Susitna River basin, where seasonal melt flows through Clear Creek toward the southern margins. Without established settlements or roads, the map focuses on the natural survey boundaries of Townships 19 through 21 North and Ranges 9 through 10 West, providing a baseline for environmental study and land management in this wilderness area.
