The Tualatin River snakes through a fertile agricultural landscape of the northern Willamette Valley in this 1916 study. The map captures a critical transition in transportation history, as established river crossings like Boones Ferry and Grahams Ferry operate alongside a dense network of steam and electric rail lines. The Southern Pacific and Oregon Electric systems connect growing hubs such as Beaverton and Sherwood, while smaller spurs like Cook Spur and Clutter Spur highlight the region's industrial reach.
