1952 Map of Seward D-6

About this map

Girdwood stands at the northern edge of this coastal landscape, where glacial waters from Glacier Creek and Winner Creek descend toward the shifting mudflats of Turnagain Arm. In the early 1950s, the region was defined by the critical transit corridor of The Alaska Railroad and the newly developed Anchorage Seward Highway, which trace the shoreline toward the settlement of Portage. The interior reveals an industrial and logistical footprint within the Chugach National Forest, featuring the Twentymile Sawmill and the Lower Engineers Camp. Small stop points like Lyon, Taylor, and Bertha line the southern mountain passes, while aviation infrastructure is represented by a local Air Strip and an Emergency Landing Field near the Placer River Valley. The map detail captures the complex drainage systems of the Twentymile River and Glacier River before modern development further altered these tidal flats.
