About this map

The high alpine crossings of the Cascade Range dominate this early 1960s study, centered on the critical transportation corridor at Snoqualmie Pass. The map highlights the complex infrastructure required to navigate the mountains, including the tunnels and tracks of the Chicago Milwaukee St Paul and Pacific RR and the Northern Pacific RR. Along the shores of Keechelus Lake, small outposts like Hyak and the Rocky Run Guard Sta serve as focal points for transit and forest management.

Water management and conservation are evident in the vast boundaries of the Cedar River Watershed (City of Seattle) and the Green River Watershed (City of Tacoma). Recreational and survey landmarks like the Pacific Crest National Scenic Trail and high-elevation points such as Snoqualmie Mtn and Chikamin Peak illustrate the intersection of engineering and wilderness. The presence of several waterfalls, including Snoqualmie Falls and Franklin Falls, underscores the steep, hydro-active landscape of the Snoqualmie and Green River headwaters.
