1979 Map of Tyonek B-1 SE

About this map

Susitna Flats State Game Refuge dominates this coastal landscape where the Susitna Flats meet the tidal waters of Knik Arm. Revised in the early 1990s from aerial photography, the map reveals a transition from the marshy lowlands and tidal mud flats to the glacial elevations of the Elmendorf Moraine in the east. The internal geography is defined by a dense network of water bodies, including Horseshoe Lake and Twin Island Lake, interspersed with sections of a historic Winter Trail. Limited infrastructure is concentrated near the moraine, marked by Red Dane Avenue, Guernsey Road, and a substation. This survey provides a precise view of the complex hydrology and surveying tracts before significant modern development altered the drainage patterns of this Alaskan coastal zone.
