1984 Map of Seward D-6 SE

About this map

Turnagain Arm dominates the northwestern edge of this 1980s survey, where the glacial waters meet a landscape defined by the Placer River Valley and the Twentymile River. The settlement of Portage serves as a critical junction point at the head of the arm, marking the transition from the tidal flats to the interior mountain passes. To the south, the Explorer Glacier carves through the high terrain of the Chugach National Forest, feeding into Portage Creek. The map provides a detailed view of the infrastructure and natural drainage patterns of this transit corridor during the mid-1980s, including the smaller waters of Luebner Lake and Skookum Creek that dot the valley floor. This area represents a vital geographic link between the Municipality of Anchorage and the Kenai Peninsula Borough.
