Oregon City and the Willamette River corridor anchor this pre-World War I survey, showing a landscape defined by industrial power and burgeoning suburban rail. The river is the primary artery, featuring the dramatic Willamette Falls and various riverboat access points like Ottawa Ldg and Buchmans Ldg. The region's early 20th-century connectivity is visible in the dense network of lines including the Oregon Electric and the Cazadero Line, which facilitated growth in settlements like Milwaukie and Oak Grove.
