1917 Map of Diamond Lake

USGS Topo · Published 1948

About this map

Diamond Lake and the surrounding high cascades of the Umpqua National Forest dominate this topographical study from the mid-1910s. The landscape is defined by its volcanic peaks and glacial basins, including the iconic spire of Mt Thielsen and the broad slopes of Mt Bailey. These peaks serve as the divide between several major drainage systems, with the headwaters of the North Fork Umpqua River and the Middle Fork Willamette River carving deep valleys through the timbered terrain.
