2023 Map of Tyonek B-3 SE

About this map

Susitna sits at the edge of a complex network of wetlands and waterways on the northern shore of Cook Inlet, where the landscape is defined by the meandering paths of the Theodore River and the Lewis River. The terrain is characterized by extensive marshlands and braided river systems typical of the Matanuska-Susitna region, with the Ivan River cutting through the northeast. Settlement is sparse, represented primarily by the pocket of activity at Susitna, which remains connected to the broader region via the Beluga Highway. This coastal corridor reflects the specialized infrastructure required for Alaska's interior logistics, where roads must navigate around vast, shifting delta environments. The map documents the intricate hydrology of the area, showing how the natural drainages shift as they approach the inlet, a vital reference for understanding the physical geography of this coastal wilderness.
