1960 Map of Mount Si

USGS Topo · Published 1976

About this map

Mount Si and Mt Teneriffe dominate the southern landscape of this 1960s study, an area defined by steep timberlands and the critical Tolt-Seattle Water Supply Res. The map documents the extensive hydrological management of the region, showing the Snoqualmie Watershed Boundary and numerous gaging stations along the South Fork Tolt River and North Fork Snoqualmie River. Beyond the water infrastructure, the industrial footprint of the Snoqualmie National Forest is evident through an intricate network of logging spurs and borrow pits.
