1941 Map of Blachly

About this map

The Siuslaw National Forest dominates this 1941 tactical survey, revealing the early 20th-century industrial landscape of the Oregon Coast Range. Timber and transport are the primary drivers of settlement here, anchored by operations like the Triangle Lumber Co and the Shotgun Sawmill. One of the most striking historical markers is the Logging Flume (Abandoned) located near the eastern edge, a remnant of older water-based timber transport methods that were being superseded by rail and road during this era.
