About this map

Dawson and Glenbrook anchor this landscape along the foothills of the Coast Range, where the timber economy is etched into the terrain. The map reveals a complex network of logging infrastructure, highlighted by the Hull Oakes Road and an Old RR Grade that traces the path of earlier industrial transport. Water dominates the geography, with the South Fork Alsea River carving through the center of the sheet, punctuated by Alsea Falls and Green Peak Falls.

Elevation changes are marked by prominent peaks such as Walters Mtn and Flat Mountain, while the northern boundary is defined by the Mc Closkey Ridge. Local history researchers will note the numerous quarries and borrow pits scattered across the hillsides, indicating the active modification of the land for road building and resource extraction. The southern portion of the map identifies the crossing into Lane County, showing how the ridges and creeks like Davidson Creek and Ferguson Creek dictate the regional boundaries.
