2023 Map of Tyonek B-1 SW

About this map

The Little Susitna River meanders south through a vast network of wetlands before reaching the glacial waters of Cook Inlet. This coastal landscape is dominated by the Susitna Flats, a wide expanse of tidal marsh and alluvial deposits that defines the western edge of the Matanuska-Susitna region. While the terrain is largely uninhabited, the presence of the Little Susitna Airport in the northern reach suggests the importance of bush aviation for access to these remote wetlands. Near the southern shore, Point MacKenzie stands as a prominent coastal landmark, flanked by the seasonal drainage of Maguire Creek. The map provides a high-resolution look at the shifting channels and hydrological patterns of the river delta, reflecting the dynamic nature of the Alaskan coast in the 2020s.
