1957 Map of Index

About this map

The Snoqualmie National Forest dominates the landscape of this 1950s survey, defined by the heavy timber and mineral exploration of the Cascade foothills. The Great Northern railway serves as the primary corridor of development, following the path of the North Fork Skykomish River through the mountain passes. Settlements like Startup and Gold Bar anchor the western edge of the map, while industrial activity is visible at the Gravel Pit near Reiter and the Lockwood Mine to the north. These mining and logging operations are linked by a network of forest roads and an old railroad grade following the Sultan River. The terrain is characterized by dramatic elevation changes, from the river valleys to the heights of Mt Index and Mt Persis, with notable natural features such as Wallace Falls and Big Greider Lake highlighting the complex hydrology of the Snohomish County backcountry.
