About this map

The Alaska Railroad cuts through the river valleys of the Matanuska-Susitna region in the early 1950s, following the drainage of the West Fork Chulitna River. This high-altitude landscape is defined by the massive Alaska Range and the southern edge of Mt McKinley National Park. The survey illustrates the era's industrial activity with the Golden Zone Mine and Silver King Mine perched near Bryn Mawr Creek, highlighting the region's mineral extraction history during a period of infrastructure expansion.

Waterways like Ohio Creek and Honolulu Creek create a dense network of tributaries fed by glacial remnants such as Eldridge Glacier. The map identifies several triangulation stations, including VABM Copeland and VABM Joyce, which served as critical survey points for mapping this complex terrain. The presence of Hurricane Gulch at the southern boundary marks a significant engineering challenge for the rail line as it moves toward the interior.
