1920 Map of Siltcoos Lake

About this map

Siuslaw River commerce and the coastal timber industry of the early twentieth century define this survey of the Oregon coast. The landscape is dominated by a complex network of freshwater lakes, including Woahink Lake, the sprawling Siltcoos Lake, and Tahkenitch Lake, which are separated from the Pacific Ocean by a narrow band of dunes and the Siuslaw National Forest. Settlements like Florence, Glenada, and Cushman are clustered near the river mouth, reflecting the era's reliance on water-based transport and the growing reach of the Pacific Southern railroad line.
