1975 Map of Skykomish River

About this map

The Skykomish River corridor serves as the central artery for this mid-1970s study, tracing the transition from the agricultural lowlands near Monroe and Carnation into the high wilderness of the Glacier Peak Wilderness. This landscape is defined by the three forks of the Snoqualmie River and the industrial footprint of the Burlington Northern railroad. Notable historic sites include the old mining camps at Monte Cristo and Silverton, along with the Old Cascade Tunnel which marks a significant chapter in transcontinental rail history. The map also documents institutional and recreational landmarks, from the State Reformatory near Monroe to the Garland Mineral Springs and the Pacific Crest National Scenic Trail. The varied terrain, moving from the Sultan basin to peaks like Mount Index and Gunn Peak, reflects the dual identity of the region as both a resource-rich timber zone and a protected wilderness area within the Snoqualmie National Forest.
