1975 Map of Snoqualmie Pass

About this map

Snoqualmie National Forest and Wenatchee National Forest dominate this mid-1970s study of the central Cascade Range. The landscape is defined by the critical water storage of Keechelus Lake, Kachess Lake, and Cle Elum Lake, which feed the eastern valleys. To the west, the watershed around Chester Morse Lake and the Green River highlights the complex resource management required for the growing Puget Sound region. Heavy rail infrastructure remains a prominent feature of the corridor, with the Chicago Milwaukee St Paul and Pacific and Burlington Northern lines threading through the mountain passes alongside the fledgling Pacific Crest National Scenic Trail. Small mining and timber towns like Roslyn, Ronald, and Lester appear alongside airstrips at Bandera and Easton, illustrating the mix of industrial legacy and modern wilderness access during this era.
