About this map

Girdwood and the base of the Alyeska resort area serve as the northern anchors of this 1990s-era topographical study. The landscape is defined by the receding ice of Portage Glacier and the tidal expanse of the Turnagain Arm, where the Seward Highway follows the shoreline before turning inland toward Turnagain Pass. This period shows the developed recreation infrastructure within Chugach National Forest, including the Portage Work Center and multiple campgrounds such as Williwaw and Black Bear.

The southern portion of the map traces the Placer River valley, a corridor where rail lines and roads converge near the Lower Engineers Camp. For those studying the evolution of Southcentral Alaska, the map preserves the exact layout of historic routes like the Winner Creek Trail and the industrial footprints of gravel pits and communication sites like the Microwave Tower that supported the region's mid-century expansion.
