About this map

The Tualatin River meanders through a landscape of agricultural valleys and timbered ridges in this pre-war survey. This era shows the region’s development through its extensive network of country schools, including Grabel School, Rosedale School, and Mountainside School, reflecting a settled rural society. Industrial and communication infrastructure is notably represented by the Mackay Radio and Telegraph Co KK-KGH installation in the northwest and various rail spurs like Cahalin Spur serving the hinterlands.

Downstream along the Willamette River, the map records early riverfront landmarks such as Miners Landing and Yeaters Landing, alongside the commemorative Champoeg Monument. The presence of Southern Pacific and Oregon Electric rail lines highlights the transport corridor connecting the valley to the growing centers of Beaverton and Tualatin. The detailed contours of the Chehalem Mountains and Bull Mtn provide a clear view of the natural barriers that shaped local settlement patterns and the placement of towns like Sherwood and Newberg.
